This has to be one of my least-involved conversions yet

.
For starters I bought Mike's motor mount and servo plate for this truck, but the motor mount is for the X1-CR buggy so I can use a 46t spur. The whole center diff is actually from a Hyper 7

.
Motor is a Medusa V2 36-60-1600, ESC
was a Mamba Max with 4 extra 35v 330uf low-ESR caps and CCBEC. After the MM smoked on 5s I got a MMM V2, which died a slow BEC death (I actually watched the BEC voltage dip down using the telemetry on my React). So for now this truck is ESC-less, but I just sent in both ESCs to CC today for replacement.
The battery tray on here is the type I usually make, 1/8" thick polycarbonate. What's different here, though, is that I wanted to use the Z-brace to brace the center diff area, so I drilled and tapped two holes that secure the front of the battery tray. The back of the battery tray is secured with a 1/4" thick polycarbonate spacer the mounts to the chassis where the engine mounts normally go.
Battery is an Impulse 5s 4800mah 20C, and the servo is an Airtronics 359. The gearing is 14/46, for about 45mph. It drives well, but the shocks need some thicker oil.
