The two rx issues I've had were on unmodded bipes. Ok I took the spars off of one. The ones I wore out seem to be battery issues. They had approximately 40 hrs flight on them, or around 250 charge cycles. Thats four flights a day for 2 monthes. I haven't seen any issues since I added the ribbons. Our weather pattern switched and I lost 2 planes in 2 days. Now they have ribbons. I only got one back. The ribbon material could be an issue though. I'm using silk, adds drag but almost no weight. Clothe or nylon ribbon would weigh more and could create issues.

BTW, on the underwing mod Im down to 1 inch from the fuselage. Still good. Tim
