For what it is worth I am using 5945's all around and JR8611 on the rudder. Even put a digital on the throttle. Over 20 flights and mine is flying great. Walls are really quick with the digis. That JR8611 is a beast as well, If I could handle it it would KE loop no problem(I always chicken out of the KE loop,lol) One thing you might look at is the Fromeco Lio-ion packs. There very light weight and last forever. I am using 2 x 2200 for the RX and 1 x 2200 for the ign. I can fly for a week(at least 10 flights) before charging
