Just a suggestion guys!
With all the radio problems that I've been reading.
Simple fix is a fail safe. For those who don't know
what it is? Simple it connects in between your reciever
and your throtle/brake servo. You set it to apply brakes
if you lose radio contact. You lose signal it applies brakes
No more running wild RC's.
They run about $30.00 nib at lhs. I will not run anything without one.
check e-bay search fail safe.

Just my 2 cents.
