I was thinking about getting another set of lipos for my revolt which I am going to be running in p-limited offshore. I already have a set of dinogy's but I just want to get another set for testing and practicing. I was wondering which is best out of these three. Turnigy 4s 4000 mah 40c, turnigy nano tech 4s 4000mah 45c, or zippy flightmax 4s 4000mah 45c?
