RE: World Models Patty Extra/DA-50
A 4 channel radio would be the minimum, but will work. You will need to manually set up choke and set up the throttle idle trim to be able to kill engine from radio(safety thing). It would be a shame to drop $1000+ on a rig and not spring for a $300 radio and get expo and separate channels for elevators and ailerons plus choke control, idle-up, throttle kill, dual rates (much more enjoyable flyer). I have a GP 1/4 Patty w/DA-50 set-up....world models a good choice w/ a da-50.
