SVT's Budget Honcho Build Off Entry

Greetings.

Let me start off by introducing myself.

My name is Derek, some of you may know me from my work with the TRX-4, TF2, and a pile of junk loosely based on a SCX10.

Now, I'm back and ready to ramble, side track, and occasionally build another truck.

Even though I was completely snubbed on my invitation to the SBG/Harley budget build off, I'm going to build one anyway. The man can't keep me down!

My build will live here, on the great pages of RCC, and not on YouTube. There are 2 reasons for this:

1. 2018 is the year of making good RCC content, not the year to make 1,000 threads on how to fit 2.2s on your TRX-4. Do better everyone, do better.
2. I would be terrible on video. The lighting in my garage is bad, I would forget what I want to say, crappy video editing, and so many other things that would lead to terrible production quality. I guarantee any video of me talking would be unwatchable. Play to your strengths, eloquently expressing thoughts verbally is not mine. 90% of YouTube should follow my lead.

For those that don't know the concept of the Harley budget build, it is $50/week to spend on whatever you want to make the truck better. Whatever you don't spend one week, rolls over to the next week. This makes for good weekly content when you are a YouTube glory boy but I, as a man of the people, know shelling out $200/month on RC junk doesn't fit into everyone's lifestyle. I will define my build as $50 per stage. A stage will be a variable amount of time since I am highly unreliable and can't be boxed in to a schedule. You can follow along at $50 every week, every two weeks, every month, annually, bi-millennially, whatever. I'll shrink and expand the stages as I see fit to keep things interesting.

Got it?

Great, let's begin.

We start on the long ago day of Sunday. I was out driving my TRX-4 with a group of idiots that thought driving when it was 20* out was a good idea. Before you laugh at me from whatever crappy frozen tundra you are currently reading this from, just know we are all pathetic in our own ways. I have watched Canadians nearly suffer heat stroke in 78* weather while locals were still wearing pants. Anyway, the cold must have slowed down that part of my brain that handles rational thought because I left our driving locale and headed to my LHS.

Some cash exchanged hands and we arrive at this point:

It's a box with a truck or a box with an old toaster that weighs approximately the same as a truck, I didn't really know until I got home.

Turned out there was a truck in there.

Enjoy some hasty pictures I took before work.

Naked turk. Hot.

What is this? Safety? Who the hell needs that?

New transmission case. It's great.

Sorry, it's grey. I meant grey.

New plastic links. I cannot stress how much better these are than the previous plastic links. Much stiffer and much more material around the pivot. While I generally agree with the sentiment of "eww, plastic links", these are probably as good as the aluminum links off the old SCX10.

EnA4j2El.jpg


New one piece front axle. It looks good, the dogbones do not. Time will tell how the built in c-hubs hold up. That "we tried way too hard to make it look cool" steering link has quite a bit of flex. The much more utilitarian looking steering and panhard links have none.

j1BKFFkl.jpg


The rear axle looks much better without lockouts. Don't know if anything else is better yet.

h6e3RSil.jpg


I will gladly call this the best looking Axial RTR wheel and tire package to date. The Wildpeaks are solid tires for loose terrain but I have little faith in the RTR compound.

LcVk1tRl.jpg


A few other bits of note:

There is a new 1-piece battery and servo tray. I like this design much better than the too many piece version of the SCXII kit. Servo winch line routing provisions have been lost though.

emKSxmLl.jpg


I have a confession: I have never owned a Honcho in all my years of crawling. Even having never owned one, I knew I would hate the bumper. While it is sucked all the way in out of the box; it still looks bad and sticks out a ton. Bummer they use a old SCX10 bumper mount, there is major flex in the mount. The SCXII bumper mounts are lightyears ahead of the old ones and it is lame they went back in time for these.

lGH5vOVl.jpg


Some good stuff in the spare parts bag. A bunch of light buckets and lenses are thrown in as well as a nearly full set of rod ends for future link upgrades.

Look! A spare tire mount!

Now everyone can stop complaining about everything that is missing from the old Honcho.

Not pictured is the radio. "Why?" you may ask.

Well, I refuse to even acknowledge it's existence. It is a clunky, uncomfortable piece of garbage. For a tiny radio, it has an incredibly fat grip and the placement of the trigger and wheel is bad. Did I mention the radio likes to actively eject the batteries out of the bottom of the handle? That's right, you could be standing there driving and out of nowhere, the 4 AA batteries will eject straight at you feet like they were fired out of a slingshot. RTR radios have never been fabulous but every one I have encountered previously at least could hold it's own power source. Don't bother unpacking it. Instead, use your phone to locate the nearest electronics recycling drop off facility then dispose of it. You will have a positive impact on your driving enjoyment and the planet. Seriously, buy any of the hundreds of Tactic TTX300 radios available for $25 on ebay instead. It is an infinitely better radio that will bind right to the stock receiver and you will never have to suffer through driving with the stock meat tenderizer with buttons. Have I made myself clear?

There you have my box opening assessment of the new SCXII Honcho. I will be tearing down a few things to examine prior to starting the build up. There have been rumblings on the interwebs that some people have gotten metal gears in their transmissions despite the specs saying plastic gears. The new sintered axle gears will likely need a healthy coating of grease as well.

More will come as I tear into my soon to be build off winning despite not being invited to said build off Honcho.

At least you were able to get batteries into your radio. I almost had to break the battery door off in order to get it to open.
 
Ok couple of things, Stop hating the front bumper, it hauls as much snow if not more than the bed.

And the Tx? Wow! Self ejecting batteries keep you on your toes. I havent had those since my old Futaba Jr sport. I have monkey hands, you know the small palm, long fingers, and I find the Tx rather comfortable. That said it feels big and meaty. Um nevermind.

Love to see how your "budget Buildoff" goes.

Maybe you and I can have one here on Rcc. I already have a headstart, and I aint tearing into the axles or trans.
 
Awesome thread. I didnt see the spare tire mount in my parts bags. Maybe just missed it. I dont care for the front bumper either, but for now it will do.. i also didnt like the radio either at first. after using it and seeing that it has epa adjust is not to bad for a really base model radio. I think this will be a awesome budget build. Im planning on attempting maybe $50-60 a month(2 kids and 1 on the way,and lots of bills) lol

Breaking it would have been for the better.

Snow? I'm unfamiliar with this snow you speak of.

Is that like the icy, white, death power that falls from the sky every couple of years?

I'm glad your monkey hands like holding big meat but I still hate the radio.

Build off on!

Join in on the build off, the competition for 2nd is tight!

I got one of the radios with my Yeti Jr many months ago, all that time has not dampened my hatred for it.

For some of us Mr. Snow May be on the ground for up to 6 months. Many like him, but a lot do not. Often you will find people living where Mr Snow does not fall frequently. These people mostly do not like Mr. Snow.

Snow is the son of Old Man Winter. His evil sister "Ice" is very much hated by most everyone, except those who take advantage of her. You will often find them skating on her with razor sharp blades.
People often search high for Mr. Snow, but not low, and these people are often called "Powder Hounds". These are amongst the few that worship him and pay large amounts of money to be near him. Dare I say "in" him. Wierd, I know. They even build odd rounded monoliths to help apease him.
He is often nice, and people call him beautiful, though he can turn into his evil sister at times, and he is particularly nasty when he is wet, and is particularly destructive then.

Sorry for my rambling, and spelling. My monkey hands and fat fingers don't play well with keyboards. Or tiny screws for that matter.
 
I like snow.Braaaaaap!!!
That was the sound a snowmobile makes.
Oh and I will be watching your build too.
 
OK, I'm back and I bear more Honcho related information.

The first thing I wanted to break down is the transmission as there has been much internet experting on the clearly massive list of negatives of the new design.

The trans was pulled from the truck and I popped the gear cover off.

McdJ4qUl.jpg


There is a new transmission top shaft that pulls the spur gear in closer to the motor plate. I appreciate this because the spur on the old transmission was about 11 feet from the motor plate for no reason. While I haven't pulled it apart to check it out, the new top shaft has additional support for the rear slipper plate which helps with gear wobble. Top shaft play seems to be reduced as well; the spur has a little less than 1 mm of in and out play. It feels like a lot less than an old transmission.

If you are in the "plastic transmission case is a weak, cost-cutting piece of crap" camp, you will be disappointed to hear this case is extremely solid. I tried to get the motor plate to flex and it isn't budging. The gears spin free when the screws are tightened unlike the old case which required a delicate balance of tight and loose on the transmission screws to prevent binding. Not to mention (I can't believe I'm going to say this), the plastic is very high quality (I'm still talking about an Axial, right?) and threading the screws in feels like a part from a high end kit.

Remember I said some people have been getting metal gears in their transmissions despite Axial's specs? Well, I removed the transmission screws (which are all the same size as the transmission mounting screws, yay for simplicity) and was ready for my surprise.

MnA7N3Pl.jpg


ZOMG! I can't take the suspense!

Show the f$%#&$@!ng transmission already!

Patients is a virtue my friends. Does anyone want to know more about the gear cover?

Threatening me does not make things move any faster.

What was I talking about? Oh, right.

iu3JL7El.jpg


Boom! Full metal gears.

Sure they are sintered but they are waaaaaaaaaay stronger than what you used to get so stop complaining and just be happy. The gears were given a healthy coating of green Lucas grease and everything was buttoned back up. Also, I just saved $7 off my budget and I don't have to touch the transmission again. Win.

Next up was the rear axle.

Being the extremely lazy slacker I am, the prospect of having to remove the rear axle from the truck in order to get the gear cover off is about as appealing as dinner from Papa Johns (which is indisputably the worst, if you believe otherwise you are wrong and have much in your life to reassess). Luckily, I bought these fancy-ass Revolution Designs ball end drivers on Black Friday.

v9YDJ41l.jpg


Sorry, I just can't stop winning.

Gear cover off.

8g1SucNl.jpg


The gears have been nicely greased but there was way too much side to side play with the 1 piece gear/locker.

To pull the axle shafts out, you remove these 2 screws on the end of the axle housing. They are unnecessarily long for just retaining bearings.

qNww8pol.jpg


1 shim on the gear side was all it needed, all play gone and proper gear mesh. 1 Traxxas axle shim was also placed on the outside of the pinion shaft.

f1igifKl.jpg


Everything was reassembled and I noticed the rear suspension wasn't articulating fully. One shock couldn't fully compress because it was overfilled.

BDYgbjwl.jpg


That is about all it could compress out of the box. A quick rebleeding and we were back in business.

Hey, it couldn't do that before.

Nper0usl.jpg


Notice the screws on the spring cups?

The Honcho has some spiffy new clamping spring cups but you have to provide the hardware. I used some M2.5x8 screws from my screw assortment.

SgTK15xl.jpg


That is as far as I got last night because it was cold in my garage and I didn't want to stand out there anymore. I'll thaw out and do the front axle later.

The news tells me that Mr. Snow dude is coming today to kill us all. If I don't return, avenge my death.
 
The snow came and now the snow is sort of gone. To the delight of some and the displeasure of others, I have survived. The fate of the other 1+ million residents of the Raleigh metropolitan area are unknown.

On a more serious note, more preparations were done on the Honcho as I was trapped in the house.

Remember what I did to the rear axle? All that was don't to the front as well.

fvakDs7l.jpg


Go back to the last post, I'm not explaining it again.

Some materials was shaved off the panhard bar to make room for the servo horn. More could be taken off but it is good enough for now, I have other plans for this area.

GLu0PtDl.jpg


Like my spiffy pink pit towel? I abandoned the garage because it was cold. The kitchen is warm and I am weak.

At this point, the Honcho is nearly ready to drive but there is one more thing to address.

aTd54BRl.jpg


Anyone see the problem here?

Did you say awful, terrible motor connectors? You should have. There are lots of things I can overlook on a $329 RTR, awful connectors aren't one of them. I don't know why any manufacturer insists on using motor connectors that were invented sometime around the Bronze age.

Speaking of terrible electronic connections, have you ever looked at the garbage Axial solders to the motor tabs? I hesitate to call it wire, it is more like a paper clip in Plastidip.

L2ItKV2l.jpg


Do you see this? There are servos that use more substantial wire. I soldered up new leads with some proper 14 gauge wire. Is this necessary? Maybe not but what the hell for 2 minutes of work.

tsK40uUl.jpg


Proper 4mm bullet connectors were added for the motor because this is 2018, not 1618. The Star plug for the battery is perfectly acceptable for most people but I use XT60s so it had to go.

While I was at it, I checked the output on the light connectors. They output 6V to each the front and rear lights. Plugging them into the receiver after an ESC swap shouldn't be an issue in the future.

The last electronic change I made was bind up this Tactic TTX300 because, well, you know why.

KgqPLU0l.jpg


You can find plenty of them ripped from Axial or Arrma RTRs on eBay for $25.

The Honcho come out of the box ready for enormous batteries. This is fine for the RTR 2S or the "I need 11 hours of continuous run time" crowds, not so much for me. A couple of the battery stops were added to keep my 2200-ish mAh 3S packs from sliding around. A hole was drilled to mount the stop in front of the pack.

CfdbSv9l.jpg


Nice and snug.

j1cvXr2l.jpg


The Velcro sits in the middle of the pack so there is little chance of the pack slipping past the strap.

At this point, the truck is ready to drive. I guess since I spent some money, I have to call this a stage.

So in the preliminary stage, I spent approximately $30 for the radio, connectors, and some wire. It is approximately because most things were pulled out of my supply of electronic accessories.

So some money was spent before the truck ever touched the ground but sometimes RTR really means "ready to rebuild". Lol, right? I bet you never heard that one before.

More stuff to come.

Later.

was seriously considering doing a honcho build off myself... but then I thought to myself I have a pimpinrocks 56 ford f100 truggy... a Jeep MJ bomber truggy... do I really need another truggy? I don't know...

awesome work on the build off so far :flipoff:

Don't let a little thing like 1 or 2 or 11 other incomplete projects stop you from starting a new one. I know I never do.:mrgreen:
 
Ok, it’s time for my first post and you’re the reason I’m ready. Your perspective on a build is both informative and entertaining. We’re playing with toys; they should be fun. We’re playing with expensive toys; they should be engineered well. Or, at least they should be modifiable by learned sages like yourself. I’m impressed and ready to learn. I’ve had 3 rigs to work on. All used. An AX10, SCX10 and now a 10.2. I’m happy with details in all of them but interested in using this RTR’s tranny/mount because it takes up less room. And, I’ll be following along because I think I’m picking this RTR up for my wife’s first rig. Thank you so much.

Do a build off with something u have. Set a weekly/monthly budget and let it rip

I'm honored to learn I am inspiring, being informative and entertaining is still a highly questionable claim. Either way, I should make it my new signature.

SVT923: Informative, Entertaining, Inspirational

That gave me chills.

Anyway, grab a Honcho and join in the fun. "thumbsup"

Who wants another free mod?

Great but you have to hear a story first.

Still interested?

OK.

A long time ago, I bought a 10.8V cordless Dremel because of convenience and portability. Now, it still works well enough but has the remarkable to die whenever I need it. Get a new battery right? Wrong! Get a new Dremel like any rational hobbyist. My wonderful mother got me a brand spanking new corded Dremel for Xmas. I now wield immense rotary tool power and what parent doesn't love when their kids enjoy their presents?

I went through all that to say I cut crap off my truck.

Choppy, choppy

7YqTNj2l.jpg


Much better looking.

7R73cA0l.jpg


Look at all that clearance. Look at all that need for inner fenders. Good thing I have ideas occasionally.

Unfortunately, no amount of chopping will fix this:

KE9w4Yfl.jpg


I could land helicopters on that front overhang. I mean, they would be small helicopters but you get the idea. At least my truck looks better, that is what really matters.

Also, I found a very important use for one of the spare parts in the box.

X6SZZkAl.jpg


It was warm here yesterday, I needed the breeze.

Boxes should be rolling in soon so the good stuff can get underway. Oh, and I guess I will drive the Honcho at some point as well.
 
Who is ready for stage #1!

Splendid.

Everything will be given away in this 1 picture.

vHlpSerl.jpg


I'll let you in on a little secret: dogbones suck. Oh boy, do they suck. Look at that steering angle, only about 30* out of the box. Crawlers need maximum physical steering throw to compensate for the lack of differentials otherwise you get a turning radius of a school bus. I own a SCXII kit version as well so I know there is much more steering available with some work.

The biggest piece of the better steering puzzle is universals. Enter these Hot Racing AR44 universals.

gDSejX3l.jpg


Why Hot Racing? Well, they mostly make pretty good parts and some very good parts. Honestly, I would have bought the Axial ones but they were out of stock at Amain when I placed my last order so here we are. Sometimes availability is the best ability. The HR versions are $5 cheaper which fits the whole budget thing. Overall, they seem pretty solid but the fit into the locker isn't very impressive. The tang doesn't fit into the locker as tightly as the stock dogbone, these will likely end up wearing out the driveshaft slots in the locker.

Here is my very untechnical analysis:

Dogbones - Approximately 30* working angle
6xqElYkl.jpg


HR universals - Approximately 60* working angle
7fmLPbLl.jpg


A side by side visual:
6SiyKPol.jpg


So you can't just throw in a set of universals and expect huge performance gains because of these massive steering stops.

s0Mp4Bul.jpg


Axial really doesn't want people oversteering their dogbones. Even with no driveshafts installed, the knuckles can only turn about 30*.

So time to hack and mangle Axial's hard work.

f3edsmpl.jpg


Ahh, much better.

C0xG9XFl.jpg


While I was taking things off the front end, I decided to free up some more space for suspension movement by installing this Locked Up high clearance panhard bar.

O67QE4Yl.jpg


While the stock panhard bar is pretty good for plastic, it is super fat. Other panhard bars that use M4 rod ends aren't much better. The Locked Up bar uses M3 rod ends (I used Traxxas ends) which creates much more clearance with a slimmer profile. Did I mention this is a whopping $4 upgrade?

pTBTDxol.jpg


Look at all that room between the panhard and servo arm. That will serve me well for a future upgrade to an aluminum arm.

Geometry preserved. Hooray, I love geometry.

rYA2gdgl.jpg


There she is, all buttoned back up.

4F8IOvLl.jpg


With the HR universals and trimmed steering stops, the Honcho now has a steering angle of about 50* before the tierod hits the diff cover. If you will notice, the tires can now hit the edge of the chassis side plates. Some trimming may be necessary if it is a problem, I'll leave it for now.

4pZrqwLl.jpg


So to recap phase #1:

Hot Racing universals: $34
Locked Up panhard: $4
Traxxas M3 rod ends: $4

Phase #1 total: $42

(Over)/under budget: $8

Phase #2 budget: $58

I'm done for now, I promise I'll drive the truck eventually.

Maybe.

Just FYI...
Your universals angle check above does not prove it will actually operate at 60 degrees. You can turn most universals 90 degress, it doesn't mean they work at 90. Corners of the tabs may touch when cycling.

They do operate at 60 degrees, that measurement was taken at the point where the tab corners touch. Axial universals are good for about the same amount.

You are correct they can turn much more than that but not all the way through the revolution. They lock up pretty harshly past 60 degrees.
