Ultramaxx Tranny'
 

They claim to be "rare". Are they any good? If they are can't see why they have stopped been produced. :rolleyes:

Worth getting one if possible?

Dont ask me. I'm just starting my own M.truck project and papa's truck made my poor soul feel despaired. I think I should wait a bit longer befor I get myself a monster maxx.

They are rare and are very nice. However they are heavy. I know there are a few people here that have them and have not installed them. Most get them aand then sell them like I did.

Ah, those are the ones used by Promod in one of his trucks with the Hacker 12XL. That was quite a while ago.

What would be an alternative for the main gear?

Most people including Mike did not change the main gear.

I'll pass then, thanks alot guys.

Anytime, Nick.

if you have a powerfull truck, you will need those gears. i have the first gen. and bought two sets of the 3rd gen, and sold them.

The UM gears are nice, but HEAVY as Papa mentioned. A single speed tranny with a steel idler gear will handle almost anything you can throw at it with less weight and a lot less rotating mass than the UM gear set. I have run up to 6s Lipo(lot of power!) with the single speed and stock lower gear and haven't had a hint of trouble. IMO, they are not necessary at all.

Unless you run 2 2240 lehner motors on 40v :p I dont think anyones crazy enough to do that.

I'm crazy enough to use two 3080/10 motors and 120 volts. However, it neeeeeeeeeeeeeeeeeds money.:D

now that is messed up, 120V! Thats gonna be a lot of batteries!

Then why they invented lipos?;)

Yeah, but even 120V worth of lipos is a bit of batteries.....
