Hey Righty,

You can just take the radio equipment out of your present plane and
use it on the 4*.. Or just get you another flight pack.. Rec./servos for
your JR transmitter for the 4*..

On reversing a servo... It's just the way the servo is placed in the plane
which may cause the direction of movement to be changed.. "norm" or
"reversed" Most radios have a switch so you can change it if you have to,
BUT... If you do a GOOD pre-flight check.. That should be no problem in
forgetting on the set-up.. But it has and does happen..
