On my Belt CP I also use the Flight Power EVO 25 2170mAh, Futaba S9650 for the tail, and JR DS285 for the cyclic. I love the Flight Power batteries, plenty of power. I get good response out of the S9650. The DS285 servos center well and have enough torque for scale type flying, but since mine don't have metal gears I don't know how they would do in a crash. But JR does offer them with metal gears. I use the Hobbico accu-cycle charger with a flight power balancer. The balancer does it's job well. I also like the charger because it has many display options so I can know what is going on with my batteries. Flight Power doesn't have a common balancer connector like E-Flite and Align do.
