I put the RSpro in the CRT.5 instead, pushing that 2500kv LRP motor. Used a dimension engineering BEC and Luciano 25V cap bank. Using Throttle Profile 3 and like it alot. Temps on both the copper post and heatsink were the same @ 104F after one battery pack(4s A123). Brakes are typical Tekin and just the best. Pinion used is 15T. I used some more Thermal foam tape between the heatsink and metal plate. Used a wire to keep the ESC in place during impakt. Now I just have to make the wires look pretty.
