I dont think running a novak would be crazy. you already own it and they do have enough power to be fun. I actually am planning on running a novak 7.5 with an lrp comp when mike finishes the conversions. The only problem I see is that you probably have a SS or SS+ esc since you have the 5800 motor. Neither one of these esc's have a lipo cutoff.

as for batteries, I would try to get something that would handle more amps. I think the maxamps 2s 5000 would be a good fit but will run you about $90.
