Fist of all.... 4s setup is only the begining... I think the really big thing is the 6s config. You'r right that 14.8*1800=26640 Rpm can be low,....... but don't forget that i have 2 motors inside instead of 1!
I had a mono 2 boat with 4s 4400, 2300kv motor inside (34400 RPM) and with this config run about 70-80km/h.
The 4s setup is good for 70-80 km/h ....i hope..
