Ok cool thanks guy's...also the boat should't be to much of a handful it's a 29'' titan mono hull that most guy's already run 4s and a 9xl so to use my 5s truggy packs I just stepped down to a 10xl. It needs duel packs for balance and my 5s 6000mah pq packs should work nice in parallel and give me about 35-40 minutes of run time (I hope). I would drop a lehner 1950 in it but they are ultra hard to come by and the hackers are sweet but obsolete (based on price). Maybe I'll look into this new medusa everyone is talking about.
