Campy is right, and I left out a few points ,BUT, $90 is a Great buy what does it come with? if youre getting a tx,rx and batteries for both, thats a great buy,,if its just the tx then its not worth it,,Futaba is a good brand a lot of people use I have 2 of them and a GWS, if your just gonna be in parkflyers GWS is a good buy at about $125 for a tx, 2 micro servos, and a small battery, but you need 8AA cells for the tx, so what are you getting for $90?...Rog
