Paul785- I have one of those hopped up jets from Steve Dale from down under. I put a 4400 with a modified jet with 2- 1350maH 40c lipos in parallel in saddle pack setup. Haven't run it as winter is almost over. Have a good day. No need to reply.BTW I see HKing has 2 new boats-1 is a mono and one is a BJ copy! Look nice with a 2815kv on 3S on both.
