Just received this Hot Trick Red Prince/Blackfoot chassis. I have another one that I am building up with Imex dual wheels and 8 tires.. but just couldn’t pass this one up. Wow..whatta mess! Front end isn’t bad, msc & rats nest wiring, Losi motor, hopefully Kyosho gold shocks..then the elephant in the room..what kind of gear box is that?!?

It doesn’t look handmade, no diff action, can’t turn rear axles by hand, appears to have two counter gears inside.. a tractor pulling gearbox??

Stay tuned for the teardown..

Electronics removed.. Airtronics 94631 servos, rx and a RC10 MSC?

Very cool! Gotta find out what Revolution it is....either a Killer, Brutus, or Insane

How do I tell?

Front end removed..





Note the increased rear track width and spacers..



Rear end assembly removed..funny how this massive structure was only fastened down by (4) 4-40 screws!

Quick clean on the chassis and esc shelf. Has a lot of extra holes but minimal running wear..





Rear end breakdown..

Waiting on the opening of the trans...

"How do I tell?"

not real sure...hopin someone on here knows how.

That gearbox was made by the guys that made Stonehenge! Might last as long too!

Armature has a “1” or “I” on it with a white paint mark.

Anyone seen a gear box like this? It has a massive gear reduction, machined housing, all gears ride on bearings, locked differential using Thorp parts.. I am pretty sure the dogbones and rear axles are Thorp too.

Given me some ideas for a box of Meccano I've got....

Its a double turn, so its an "Insane" (15x2) or a "Killer" (14x2)...the "Brutus" which is the holiest of holy grails is a triple (16x3)

After going cross-eyed counting all the teeth on the gears... this gearbox has a final drive ratio of 114 to 1! Anyone want to play tug of war?
