ACME Pusher V3 (MOA 2.2)

[st4nd4l0n3]

Hi, I don't see any specific category for this rig, so I'll post the thread in here.

When I first saw the acme rock crawler, more than a year ago, I was captivated. I don't know, I think it was something about its ugliness (some may say 'purposefulness';) .

I Knew it wasn't ever gonna be as competitive as the berg or the bully, but I wanted to give it a try and see what I could get out of it.

So this is our (my bro and I) rig preparation:

Looks interesting, the placement of the motors reminds me of a losi with the MOA kit.

Nicely done. That is a very interesting rig for sure. I honestly hadn't heard of them before. How do they perform? Also wondering are the worm pinions hard on motor bearings? Seems like the force of the worm gear right on the 1/8 shaft of the motor might be problematic? Any vid of it doing it's thing?

great to see another one off these.

i also bought one like a year ago for its trans moa axles and crazy bulky build.

mine, I has started to mod and then rebuild.
looked like this last summer with just a few mods too it.



but now i have started too look into the posebilitys off the axles, like narrowing them to axial widht

Yep, I don't think they were ever sold in the states, and as far as i know they were never very popular in Europe anyway.

I think it shouldn't be a problem since the shaft of the motor gets all the angular speed(rpm), but very little torque(moment).
