Or, they have a short life span

My 1st lost a wing half in a high rate roll - nope, didn't fly it knife edge and then roll it for a 3-point landing. Ibashed the kit's use of a "J"hook and #64 rubber band to hold the wings together - used 1/4x20 nylon bolts. One vibrated out mid-flight.

My 2nd had a battery with one cell that was bad, went below minimum voltage for the Rx and it rolled in at full throttle. I didn't put a load test on the battery. If I had I would have seen the voltage plummet from 5.6 to below 4.0 in a matter of seconds.

My 3rd is using a new 6.0v battery pack and the "J"hooks.

Fun, fun, fun 'til her daddy to he T-bird away ....
