I purchased this plane yesterday and its my first plane with " safe " and I'm a bit confused about how to setup my transmitter. I'm using an older dx7. It doesn't have a momentary switch or any aux1 chanel and the instructions say that the 3 position switch for the flight modes is on channel 5 but that's my gear channel . I'm sure there are some mixes to get all this right. If anyone has this setup I would appreciate the help
