1/16 Oliver Dozer Conversion

[Rvjimd]

I finally got around to creating a new dozer video with sound.

It had been a while since if had run the dozer and I think I should have NOT been using a 3S lipo, it made it faster than I remember and harder to operate. I think I probably smoked the RX. I Fahd forgotten that I eliminated the ESC...

Well, I'm on a mission from God to try and do a motor refit on the little Oliver dozer in time for Brownsville. Just got started on it yesterday so that gives me about 10 days or so to work on it.

I had been running this with servos, but thought I could do better now that I have a better selection of machine tools to work with.

Going to use these two gear motors and a esc. Really hacking up the rear end of the poor thing so it will be interesting to see how it goes.

Got the new undercarriage all assembled. Now I need to figure out how to attach the hood and operator/seat. Then, how to store and retain the lipo, RX and motor controller. If all goes well, this might be moving today. oh, ya, still need to mount the blade lift servo.

Help with motor controller...



I used one of these 2x5 RC controllers in my crane and had trouble figuring out how to use the bec. I finally gave up and used a separate battery for the RX and servos, while using the 2x5 for the drive motors. I clipped the red wires from each RX connector on the 2x5. I had all sorts of space so the extra battery wasn't a problem.

The dozer is a different story, not so much extra room under the hood, what with the giant horsepower I got in there now!

So, is this just supposed to plug into the RX and provide power to the RX thru one or both of the motor control wires?

They don't really describe too well how it is supposed to work. I don't remember exactly what it was doing on the crane, but I got tired of messing with it and gave up.

I am waiting on a reply from dimension...

Short video of the first test run of the new drive train on the Oliver dozer! I was trying to holde the batteries out of the way and film at the same time, so I didn't get a good shot of the travel clip.

GREAT job Jim! Keep us updated.

The BEC comes from the wires you plug into your RX to Sabertooth. When the main battery powers up the Sabertooth the leads have regulated 5VDC for the servos or RX.
I'm not looking at a wiring diagram but that is basically how it works.

NICE Dozer you have there! I wish I could scratch build something like that, but I'm not that skilled with metal working

Skeeter, thanks.

It is a diecast model that I converted to RC. I had to do a bit if simple machine work for the motor mounts and bearings on the drive axels but it wasn't too bad.
