OG Losi Ten-T rebuild

[Budha]

So, first build thread - a bit after the fact - lol.

My first RC was a Losi nitro Ten-T bought new way back in the day. After getting back into RC with my son and running his Typhon around I thought why not bust out the 10T.

That didn’t last long as I couldn’t get the damn thing to hold a tune, or run consistently. After dorking around with it for a couple days, I got the bright idea to just rip it apart and see what’s what.

This might the time to share that I have absolutely no clue what the hell I’m doing.

So, here we go:

Next phase - disassemble and clean.
Phase I: Disassemble and clean:

Phase II search eBay and way over pay for parts

Rebuild rear end, diff, and shocks:

Rebuilt front end, diff, and shocks

Modify the engine to eliminate the ROSS starter system and convert to pull start using Traxxas back plate, starter shaft, one way bearing, and pull starter:

Traxxas back plate

Original backplate

Make shift drill press “mill” to shave the traxxas backplate down

Modified traxxas backplate vs original backplate

Thanks - An ultrasonic works wonders on diffs, gears, turnbuckles, etc!!

that’s cool! The old gas days we just don’t realize how good we got it now!

Thanks! Yeah, for sure plug n play is way less hassle.

This started off basically just seeing if I could get it to run. And 6 weeks later here we are - lol.

Ok, been a bit since I’ve updated so thought I would add a few pics and update progress.

Removed ROSS electronics and new servo’s installed:

It’s almost ready to go! I fired it up last weekend and the engine is solid!!

Having a few issues dialing in the throttle/brakes and carb settings, but think I have it pretty close now. Also have a Servo twitch on the throttle Servo which is annoying….still trying to figure that one out.

Hoping to break in the engine this weekend if the weather cooperates!

Oh yeah, I picked up a 2nd pretty cherry Ten-T with a working 3.4 for super cheap on eBay last week as well

I have enough extra parts to finish this one as well, but might convert it to electric..

Man this makes we want to come over and drive it!!

Me too - lol.

Well - I got her running today and was in the last stage of the engine break in, right when the engine was starting to smooth out. Then, the electronics starting going all wonky, loosing connection, and lots of servo/throttle glitches, etc.

Luckily the fail safe worked, she almost ran away from me once, but I was able to get it to brake.

Not sure if I my receiver is going wonky (it’s the OG receiver, so it’s OLD). Or the batteries in my Tx are weak. Will test again tomorrow, if it’s the receiver, it’s kinda time to upgrade it anyway - lol.

The good news is the engine seems to be dialing in well, just hope having to stop in the middle of break in doesn’t hurt it.
