Pics and video of my Mugen MBX5T truggy brushless conversion...

However, it all went very easily... so I thought I would post up what a bog-standard (budget) conversion looks like in case anyone else was in the same boat...

I used the RCM motor mount and servo plate which are a perfect fit, and as this was my first attempt I dropped in an ESC/motor that I had on the shelf - EZrun 80A and KD36 XL 1900kv motor, running on a nice big 5S lipo sitting in a standard Tekno battery tray from Mike. If it all works well I'll pick up another MMM combo.

The old CF servo plate serves well as an ESC tray, and I put the Spektrum SR3300T RX in a Traxxas waterproof RX box, with the temperature telemetry on the motor. I got rid of the brakes of course.

The metal-to-metal drive train is pretty noisy (even more than e.g. my Savage Flux) regardless of the mesh setting (which is a bit fiddly to set btw, as the lower screw is awkward to reach). I have not tidied up the wiring yet, and the centre diff is way too loose (no wheelies here!) so will have to do something about that at some point. If I keep the EZrun in there, I'll probably put in a UBEC to give it some relief as it is only rated to 4S. Other than that and a few places where I needed to replace the stock screws with shorter ones, that was it - there really is not much more to a conversion using the RCM kit so if you were hesitating, just go for it!

Only one glitch - in the first 30 seconds of the first run the 16T pinion broke, but luckily I had picked up another size which is holding fine at the moment...

hey there
what sort of run times do you get out of that turnigy you have pictured? am curious as i have bought a couple as a starting point for my mbx5t conversion.
