WELL I finally did my one project of converting my 2nd RS4 nitro MT1 to electric that I mentioned a few pages back (I still have my MT2 nitro convert as nitro and its staying that way )

In all truth the whole conversion took me at most 2 hours, and most of that time was spent trying to figure out what I could use to stop rear chassis flex, and mount the ESC.

Battery tray is a cut down Traxxas Stampede Chassis (found it for $10 shipped )
motor for now a 35t Saturn (out of my Brama) gonna pop in a 27 turn once it arrives. Ran it for 20 minutes today at full throttle, and it the motor didn't even get warm to the touch.
ESC is a HPI (again out of my Brama)
Motor mount is some cheap airplane mount I dremeled the hole bigger.
Pinion gear is a 11 tooth MOD 1 by Novak (had to also 3/16 X .028 stainless steel tube to make a adapter to fit the motor shaft)

I used a spare front shock mount to mount the antenna and to make a place 2 run 2 cut down parts trees to the rear shock tower, which I zip tied the ESC and power switch to.
there is a stronger brace underneath the ESC that I had leftover from the MT2 wing mount mod I did a few months back.

In all truth I was actually shocked at how easy it all went together. And if the 27t motor doesn't get warm I'll probably drop in the 20t motor I have in my Brama and see how it does with that.
