Axial 1/18 Yeti (and Yeti Score)

[monkeyracer]

So, just a few minutes ago, a neighbor from up the street knocks on the door holding a little box. It seems that the UPS driver delivered it to them. But here's the problem, they are about 1/2 mile up the road, and the address is not even close to mine.
I'm lucky they are honest neighbors, and didn't open it or try to keep it, etc. But I am not happy with UPS. The driver is supposed to contact me tomorrow to let me know where he left it, and I am interested to see what he says now that I know he left it at the neighbors' house.
But, now it is too late to tear into the thing tonight, so I will start messing with it tomorrow.

I'm relieved it is here though, and excited to start messing with it!

Really glad you got it MR. Thank God for good neighbors!

Threw some other sized tires on

1.9 stock mrc




1.55 dirt grabbers

 

[84yoda]

Those 1.9s and a brushless setup would be perfect.

Well, finally got the battery charged, popped it in, quick check and everything looks good to go. Ran it for 10 minutes and the servo is toast. This was in the garage. You guys weren't kidding either. That 25oz/in servo is hilariously underpowered and would not self center, even holding the truck off the ground. I'll call Axial tomorrow just to let them know but I won't even ask for a replacement. That stock servo is bad. The search is on for at least twice the torque out of a better servo. I can't even really say anything about the truck's performance because my time was so short but the motor did feel like it had a good amount of speed and torque to it. Fully open diffs handle great but the tires spin freely over the slightest obstacle. I'm bummed I couldn't drive it more but excited to get it fixed and run her again.

So what is a good servo that will drop in with little to no modification?

 

[SCREAMER]

Captain mentioned the Hitec HS-65mg being a drop in but that servos torque rating is the same as stock. The Hitec HS5070MH was also mentioned by blackbart and is a bit bigger but doubles the torque so I'm hoping I can get that one to fit. My LHS has a million servos to choose from in this size category so I'll have a solution this weekend. Thank goodness these smaller servos are so cheap compared to what I'm used to paying for my crawlers.

I had the SAME issue with UPS last week.. eve. Had the driver come her and scream at my girlfriend saying the GPS shows he left it in my garage. Turns out it spent the week in the neighbors garage. Now I have to sign for anything UPS cause he messed up..

Check out hitec 225mg, 54oz at 4.8v or 66oz at 6v.

 

[SCREAMER]

The dimensions on that one say it's way too big to fit. If nothing good is available in the stock size catagory we may have to mod anyway.

 

[Captain_Torquepants]

HS5070MH should work fine. It is an HV servo though so it's torque ratings are at 6 and 7.4V. Looks like it's a little deeper than the HS65MG. There's room back there, plus with no 22T spline adapter for the stock servo saver, there's plenty of room in front of it too.

Working on installing one at the moment. It's tight, but I think it'll work. The slot on the bottom of the chassis will need to be extended about 2mm longer to mount it. It's neat they include a 24t servo saver piece but I don't have a long enough screw and it's an odd size, like m2.8 or something, plus there's not room in the chassis, so I hope its strong enough.

I'm tempted to try out a Goteck servo from Hobbyking. 80oz of torque at 6V and only a few MMs taller than the stock servo. At a whopping $18, its no big loss if its terrible.

Well, mine's dead. Got to work a few minutes ago. Plugged 'er up. Drove it around the side of the building and back, on pavement, and it suddenly came to a stop. No response at all. Unplugged, plugged, nothing. Started smelling hot electronics. Popped the top and the front half of the ESC/RX combo was getting really warm so I unplugged it. Nothing is pinched anywhere that I can see. It just up and died.

I would unplug the servo and test it again but the brick must be removed to do so and I'm at work for the next 6.5 hours or so. No big deal. I had already planned on converting it to Spektrum tonight anyway but I did want to run it at the LHS's today. That's not gonna happen now.

So a lame servo out of the box and a dead RX/ESC within the first 3 days. This ready to run stuff is for the birds.

 

[Lavaheadache]

There are right angle pieces included in the spare parts to use different size servos without use of the re20 mount

 

[SCREAMER]

Called Axial this morning and they're doing what they can to take care of me. He said parts availability is so scarce right now because the truck is so new but he's getting parts on order for me. I feel bad for any kids getting one of these for Christmas having the same issue. I hope none do. That would put a bad taste in people's mouths if this was their first Axial purchase.

Sounds good.

Screw is probably 2.6mm if it's same as other Hitec. The new Hitec supposed to all go to 3mm, much better.

Do it!

 

[monkeyracer]

I don't know if it has been posted or not, but max battery dimensions are:

38mm wide, 107mm long, 22mm (or so) thick.


For servos, I was planning on trying out the Power HD 1711MG:

48.61 oz-in (6V)

It's a little wider than the stock servo, but with the servo mounts that Lavaheadache mentioned, it should fit fine. I'll probably just use one of the horn that it comes with, at least to start. I have a couple left over from a robotics project from school that I wasn't using otherwise.

I'll try to get a pic later when I install it.

*Edit* Not sure if it's disappointing or comforting that my rx/esc isn't the only one that died within minutes. Axial told me I have to ship them in before they'll send anything out - is that what everyone else has been told?

This is what I ended up ordering. Should show up Monday, and I hope to have it all in by Monday night.

Hobbywing QuicRun 1625 ESC

Hitec HS-65MG Servo

RadioLink RC4G Transmitter/Receiver with Gyro

https://www.amazon.com/gp/product/B00LX11G9Y/ref=od_aui_detailpages00?ie=UTF8&psc=1

I didn't notice until after ordering that the servo has roughly the same torque as stock... Hopefully it's still better. The RC4G seems to have good reviews, and I'm thinking the gyro will be fun to play with - all at much less money than the Spektrum.

Ah man... this is just like watching people buy the 1st year of a new car. So many problems right out of the factory. I'm gonna wait a few months, probably jump on the 2nd shipment (if it happens) hoping that maybe this RX/ESC thing is fixed. (I'm no good with binding a TX/RX and such, so I'm most likely just going to keep that stock whenever I get one). I have a HiTec HS-65HB+ that wouldn't work in my Trail Trekker w/o dropping more money into it, hopefully that will work with the Yeti Jr.
