RE: how far do you fly?
I use a JR 652 older model but still about the same year as the JR 8103 . i fly my planes up and out till they are a dot in the sky. range not a problem. use a good RX full size. the 1/2 - 1 oz more from full size to micro RX you will not see in a 4 lb heli . keep ant. out not chocked off or get a good loaded Ant. RANGE CHECK and you will be fine !!!!!
