I'm trying to figure this out. The instruction manual says you need a 4 channel. I'm thinking about getting a 6 channel futaba 2.4ghz radio (also comes with the servos S3114 that I think will work well with the Cularis). I'd rather not spend the money for the Futaba 7C. Would the 6 Channel be good enough for this aircraft? I'm mostly a sailplane/parkflyer type of person.
