E-Revo 3.3 conversion/build - 03.02.2009, 08:48 PM

Hi guys, I got my first big 4x4 truck in a trade not to long ago. I got a revo 3.3 and im going to convert it. I will be using a MMM with a medusa 36-70 on a zippy 5s 5000 lipo. My mom ordered the lipo last night for my birthday present(perps to bring 13-14, get presents!) With my birthday money I plan to buy the motor and the RCM mount if I have enough money then the MMM. This should be a beast! This is my first conversion so I need some help guys. All input accepted! here are some pics...
this s an ESC plate I made for the MMM, its made out of 1/4in lexan

Host them on photobucket and resize to 800x640.

Anyways, which kv medusa did you buy, as that will determine the correct gearing and voltage you should use.

if you plan to stick with the stock tranny, then Mike (our Lord & Master) sells all you need pretty much to convert the nitro chassi over to electric (motor mount, battery tray etc) then its just a case of deciding whether you want to lock it into 2nd gear and use motor braking via the esc, or keep it 2 speed and use mech brakes.

Plenty of tutorials and info to show you whats needed either way- welcome to RCM.

I am in the process of converting a 3.3 as well. What has been said to me many times is that the stock diffs will not hold up long to 5s power, which is what I will be running. Hence, Mike sells hybrid cases which work w/1/8 gears. They are not cheap, but, on 5s I would seriously consider them. If not the hybrid cases, at least AL inner and outer cases w/hardened gears which will reduce flex a lot.

Welcome to the madness!

haha, thanks. I have been told the diffs will hold up, I have been told they wont...I guess I will just have to find out when my 5s and electronics comeI will look into aluminum gears and cases but nothing right now, maybe in a month or two though.

I have a revo conversion running on 5s with the MMM and Medusa or Neu 1515 1Y. The stock diffs are holding out real well. It all depends on how the diffs are shimmed and how you drive.

Supermaxx with Mach .26

If you are looking at a 8xl, save a little more and get a Medusa. HUGE difference in quality.
