Hey its good to see another conversion coming along, especially one I have done before! I run a feigao 8S on 3s lipo and its a blast. I do think a Lehner xl3600 on 11.1v would be a better choice because my motor heats up quite a bit. Very easy to convert (just made a motor plate and bolted it to the chassis). I paid $200 for the truck with shipping and sold all the nitro equipment to some guys at my LHS for $40. Heres a pic, I have since cleaned up the wiring a bit and reversed the mounting of the motor so I could run shorter wires all around.......
