Trying a new servo that hopefully doesn't burn out like the Tower Pros have done.


Interior details.






Now Cletus is ready for some gear jammin'!


Anyone else tried TheDIYGuy999's homemade sound/light controller? I'm working on it now...

thank you sir, i have always wanted the Tamiya big rigs added to my fleet but i thought it would not match up with my fleet of 1/10 crawlers and also, they are quite expensive especially if it includes the sound and light module.... the other purpose is also to have a trailer which will carry a couple of those crawlers, i just thought it would be awesome... been looking around for 10th scale big rigs but cant find any...so i thought of just building one with my 3d printer and some cad skills.

Well, in an effort to make it easier to integrate the DIYGuy999 light/sound controller, I decided to pick up this Flysky i6X. I also picked up an additional receiver and between the two of them I hope to have a solution to be able to fully control the MFCU to its full extent. In time I hope to be able to migrate to a pistol grip transmitter of some sort.


So I've been having issues with the Lesu transmission. I believe I've mentioned how I've burned through a micro shifting servo and the replacement servo tends to run hot. It hasn't failed, but I think it's only a matter of time. The reason? Well, the springs are pretty strong so when you're in low or high gear there's a lot of stress on the servo to hold that gear. In middle gear there's no strain because the springs aren't at play.

After a lot of thoughts on how to deal with this I decided to tear it apart to move the shift linkage toward the front. Moving it from the rear to the front means I'll have room to use a full size servo to shift. It'll still be under load, but a full size servo should be able to withstand the load much more easily. So here's some pics of the Lesu 3 speed 4WD transmission cracked open.










So here's the shift linkage now at the front.


Now to get this full size servo set up to shift it. Hope this works like it should! I may instead mount a low profile servo with the servo horn up top. I'll experiment with a few options tomorrow.

It's cool to see your still refining this one of a kind semi.

I'm not familiar with spring tension being required to hold a gear position. I take it the trans won't work without the springs on the shift rails?

Thanks! And yes, you're absolutely right. I tried removing the springs and it didn't function. Fortunately, I came up with what looks to be a solid solution.

I now have a full size servo controlling the shifter. It's so much stronger than the micro servo I tried and doesn't heat up at all. I think that issue may now be resolved.


I also put this stuff in one rear axle to try out. It looks like it'll work better than the 2.5M weight oil I was using and shouldn't leak out. Now to do the other rear axle. No need to do the front axle, though. I have something different planned for it!


I'm also starting to make some progress with the ESP32 MFCU. I have the steering worked out, but that's all. I still have quite a bit of configuring left to do. Having to also learn a new transmitter just adds to the complexity!

So here's why I didn't bother with putting the new diff grease into the TLT front axle. Lesu locking diff with a 2.6:1 ratio. It's narrow so the tires will tuck as far as I want, they bolt up to the F350 leaf springs I'm using, they're shorter in height which will lower the ride height a bit, and with the option of an open diff and higher steering angle, it should turn much sharper. That being said, the narrow width of the axle means the tires will get into the leaf springs. Add spacers to gain more throw and the scrub radius increases, possibly causing fender clearance issues. We'll see, though! Time for test fitting soon.




Here it is with the diff lock cable attached. It also included a tie rod, which I wasn't expecting. Nice!


It's substantially narrower than the TLT it's replacing.


I almost forgot this came with my axle order! I'm really excited about the level of detail this unit will add. I think it looks pretty amazing.

This thing is off the charts cool Tommy! The build reminds of me old school RCC, but better because there are more goodies now days.

Thank y'all!

With that narrower Lesu front axle the tires tuck waaaaay more than before. And this is shown with wheels that have much less backspacing than the ones I've been using. I would actually like to space them out a bit more. The issue is the scrub radius is pretty bad and at full lock the tires get into the back/inside of the fenders. I either need to do some clearancing and/or raise the fenders up a bit.




Loving the new AC unit!


And I've got a bit of good news to report on the ESP32 sound unit. I have it operating the lights like it should, but am working on the sound now. Fingers crossed I can get it all working properly!
