I have an E-Clipse 7 from Hitec two years old this month. I have a Diamond Dust that I just replaced due to a nasty crash, however I used the same engine and reciever in the replacement. I was trimming out the maiden voyage and ran out of radio range at about 400 feet. Luckily I was able to shut the throttle off and the unit fell to earth without any damage to the plane. I change to another used chrystal and a Supreme 8 reciever and still had the same problem, my son carried the plane out to the failure piont and sure enough, at 400 feet the unit either locks up the controlls or they jitter frantically. Since that unit had experienced a crash in it's life I decided to install a NEW chrystal and Supreme 8 receiver, still the same problem. Since I have multiple models, In an attempt to eliminate my transmitter as a posible problem, I changed models and carried another model 300 feet past the failure point where it performed perfectly with the same TX. I have not changed the rx battery as of yet but have drained and recharged it. A modeler told me that the bat might be damaged and putting out rf so that will probably be my next step however, I'm curious about the chrome ultracoat I covered the bottom of the plane with. The hobbie shop states, can't be part of the problem, but I'm not convinced. Anybody have any ideas about my problem or the chrome Ultracoat possibly being the culprit?
Thanks for you input.
