Greetings and welcome to this special Friday edition of SVT's Honcho budget build extravaganza!
Yaaaaaaaaaay!
Yes, I see you are excited and yes, this is clearly better than whatever you are supposed to be doing right now but control yourself. Unrestrained enthusiasm and discretely perusing the internet don't exactly go hand in hand. So grab a chair and some coffee (or scotch, I don't judge) and gather round.
Before anyone starts in on the "what is taking so long for these updates?" garbage, know that I have been busy working to bring you a better build thread experience. A whole scale garage complete with lighting has been build to provide a pleasant backdrop for your visual intake.
Also, I switched from cell phone pictures to a fancy ass Sony micro 4/3 camera for higher quality pictures. What have you done for me lately? That's what I thought. So shut your face and be grateful.
But before we go forward, we must consider the past. Not to respect our ancestors, heritage, or any of that other crap, just to see how much cash we have to blow this time around.
Phase #4 - $106.01 + $50 = $156.01
Man, I have been cheap up to this point (that will change, don't worry).
This week is all about getting the wheels turning.......in the right direction.
See what I did there?
Lucky for anyone doing a budget build these days, there is a huge amount of low cost, high performance servos that are actually pretty good. Seeing how the stock Tactic servo is pretty bad, something that is pretty good would be a huge upgrade.
My choice for the task:
This is a JX CLS-12V7346. It has a stylish and durable aluminum case, steel gears, and makes 530 oz of torque at 11.1V.
Wait, 11.1V? What?
That's right, this bad boy runs directly off a 3S battery.
If you didn't believe me, then maybe the gigantic laser etching will convince you.
I'm have been a big fan of 3S capable servos since installing a Holmes SHV500 in my TRX4 for the power and simplicity. Just remember, you always need a BEC except when you don't need a BEC so use a BEC when you need a BEC but don't use a BEC when you don't have to use a BEC. Got it?
Unfortunately, a $120 servo doesn't fit the whole "budget" theme of this build. I stumbled across these JX servos a while back and ordered one. Then I waited and waited and waited for Gearbest to get off their collective asses and send the servo to me. A month later, they put my servo in a box then it showed up in my mailbox 2 weeks after that. So here we are in the beginning of May and I am ready to install the servo that was ordered in March.
But wait, there's more!
In case you were wondering, the 46kg rating is at 14V. That works out to about 630 oz of torque. Even if the real torque is only 3/4 of that rating, it is still hella strong.
How much would you pay for all this servo awesomeness? $100? $90? $75? $60? Find out the low, low price after this:
For those not familiar with 3S capable servos, they use separate leads for power and signal.
Some quick soldering and I had a power tap installed. JX doesn't include a JST pigtail like Holmes does with their servo but I had one laying around. You could always solder the servo power leads straight to the battery wires but I like connectors here.
A few screws and the old servo was gone.
Normally you wouldn't want to meet whoever is replacing you at your job but I don't really care what the stock servo thinks anyway.
Like the new servo horn? More on that in a minute.
Has it been a minute?
OK, I'll tell you.
So I was planning on using this servo horn from Top Hobby on ebay. They are low profile and not too bulky like a lot of clamping servo horns. Did I mention they are $6 shipped from the US?
If you think they look familiar, they do.
But alas, the horn proved to be too low profile as it hit the chassis before coming close to full lock.
Back to the drawing board.
So I borrowed a Vanquish servo horn from another truck for some testing. It clears the chassis but hits the panharrd mount quite a bit before full lock. So I trimmed a little off the panhard mount.
Better but not good enough, the Vanquish horn is just too damn bulky.
So I grabbed one of these Protek horns.
Again, hits the chassis like the Top Hobby horn. Why is this so f*$&#!ng complicated!
Further review shows the Protek arm is just barely hitting the chassis, I may be able to work with this.
I trimmed about 1mm off the height off the height of the servo mounts to drop the servo.
Everything was mounted back up.
And success!
Between the Protek horn's profile, the trimmed panhard mount, and the lowered servo, everything fits as it should and full steering is achieved. Well, technically there is more available steering but the tires will touch the links at full lock so I don't really need to chase it further.
Speaking of lowering the steering servo, I now have a convenient transition to the next topic. Thanks, me!
As you may recall from our tire discussion (or you may not, in which case you may be confused by the following), there was talk about lowering the Honcho.
Adjusting the preload collars all the way up wasn't enough, the Knight Customs spring cups were intriguing, but then I was inspired. Just mount the shocks on the same screw as the links.
All it takes is longer screws (M3x25) and 2 minutes to lower the truck significantly. How much? I don't know, I forgot to measure. 8 mm, maybe? I'll go with 8 mm, it sounds close enough.
Where did this incredibly simple but brilliant bit of information come from?
Me.
I did this on my GCM Skeleton when I installed SCXII axles to get the ride height down. I'm even more wonderful than I though I was.
As you can see, much lower.
More lower = more stabler = more gooder.
It will look better with smaller tires too.
Did I just tease our next installment? :shock:
I'll gloss over that and get to our tally for this stage.
JX 12V servo - $53
Protek 25T servo horn - $11
Stage #4 total = $64
Well done me, well done.
What do we have to work with next week?
$106.01 + ($50-$64) = $92.01
I'm incredibly qualified to perform these calculations. Would you believe I have a master's degree in accounting? There is a fancy-ass piece of paper at my house to prove it.
I would say I hope you enjoyed this installment but I know you did. Stick around for the next amazing installment.
Literally, stay seated at your computer waiting, furiously pushing F5 in hope of the next post being one refresh away. It is the least you can do.
