Aloha..The receiver problems are happening with the radio on, and range is not the issue as it happens at less then one hundred feet.. What would you recommend for a small receiver.I gave up on the motor and use it as a glider now.It flys well in light thermals. Although I can't use it until I fix this problem...PS. I used to live in Westhampton L.I.N.Y. Nice there except for the weather...Better her on Maui....Thanks Rich W....
