As you can see from the pics my J82 is built. Know in looking for a BL system for it. I plan on using my 7 cell nimh packs for know. I will get trakpower lipo's latter. So i was thinking about getting the sidewinder & 5700kv system or the MM & 5700kv system from castle. Im leaning towards the sidewinder system because of the low cost. Any thoughts ?.
