Hey Charlie,
to my knowledge the overheating was caused by Rx exposed to sun heat (let's say you had a black canopy and the rx was behind that AND you lived in Texas and it was scorching hot...) that was back then, i believe the problem has been remedied since. I would always protect my plane from the sun anyway. Just a heads up

Lost a plane to an overheating problem . . .
Futaba 2.4gHz has a receiver overheating problem? First I've heard. What voltage were you running it at? I have four 2.4 gHz Futaba receivers, three on 4.8v and one on 6.0v and I haven't noticed a heat problem.
