Good news Don. I made 200 flights per pack my goal and I still have hopes of reaching that. I have three TP5300 packs and have used the TP charger and balancer from the start. I've got 133 flights on one and I haven't detected any changes yet. I fly in relatively cool weather all year so I don't believe my packs were ever overstressed. With $150 motors, controllers that last forever, and batteries that yield 200 flights for $500 it looks to me that electric is less expensive than high performance glow in the long run. Then throw in the wear and tear on the airframe and servos and it seems the choice is clear from a cost standpoint.
