The Alpha trainer (if i remember correctly) comes with a radio that is essentially EQUAL to the Futaba SkySport... not junky. Not worthwhile replacing it.

I'll look it up and double-check. But if I'm right you'd be wasting your time.

The JR Quatro is a direct competitor with the Futaba 4 YF. they are EQUAL quality. You would be wasting your money replacing that wit the Futaba radio.

BOTH JR and FUtaba make good stuff.
