How big is the rigger? My xs2 on 4s with a hydra 240 & 4s with the 7xl & x640 prop was 60mph. The same set uo with a 1512 2d is 65 plus. You can run alot harder set ups in the rigger due to less drag. The same set up in a mono would be a disaster.

heya its around 26" and is going to be full carbon apart from balsa sponsons, at this stage anyway

Sounds like about the same size as my Matrix rigger and I run 4s in that. As with any setup just check temps alot and have fun.

4S Lipos 4900-5000 mah's. 25 C cells. X438 prop to start with to get the boat dialed in.
