Ultramaxx Tranny'

[Nick]

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?

[captain harlock]

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.

[Papa]

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.

[captain harlock]

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

[Nick]

What would be an alternative for the main gear?

[captain harlock]

Most people including Mike did not change the main gear.

[Nick]

I'll pass then, thanks alot guys.

[captain harlock]

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.

[RC-Monster Mike]

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.

[captain harlock]

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

[Sylvester]

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

[captain harlock]

Then why they invented lipos?;)

[Sylvester]

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