I'm looking for a good second nitro rc plane.i had a hobbico nexstar.I want to purchase either the futaba 9caps PCM transmitter or the JR 7 channel pcm transmitter.I thought of purchasing a low wing plane.I've considered the sig four star 120 and the great planes cherokee.Which one of these two do you suggest? Any other suggestions?I want a plane with at least a 60 -65 inch wingspan though I'd prefer a plane w/ a 70 plus inch span.I'm somewhat budget minded.Any tips are appreciated Thanks.
