Two of these...
Turnigy nano-tech 2200mah 2S 35~70C Lipo Pack
http://www.hobbyking.com/hobbyking/s...dProduct=11943
Voltage: 4s2p
Top speed: 72 km/h just before flipping
Motor temp: hot (3,5 min run time)
The max. pass was the only full throtle try. That ended to flip. The setup difference this time was that I turned the propeller lower than last time. Didn't see much change. The wearher was now better than last time. At least the torque twist seems to try to flip the boat clockwise around. This effect started to be strong already in speeds a bit less than 60 km/h.
I tested also the battery
Turnigy nano-tech 2250mah 3S 65~130C Lipo Pack
again. But lipo cut off hit durng first speed pass.
I tested also one
Turnigy 2200mAh 3S 20C Lipo Pack

but cutoff was instant destiny.
The 4s seems to be too much for this system. The 2s seems to be nice steady setup. The 3s would have more fun factor and would be interesting to test. I just don't seem to have proper battery. I just ordered one of these to be tested:
Gens Ace 2200mAh 11.1V 55C

I was thinking also this as alternative
Turnigy nano-tech A-SPEC 2200mah 3S 65~130C Lipo Pack

but decided to test the Gens ace.
