How many channel radio is this? You may be able to do the crow, but not be able to couple the flaps with the ailerons. You will need 4 channels just for the ailerons/flaps for the advanced crow. For the basic crow, use an aux. channel for the flaps, aux. channel to seperate the ailerons, have the flaps go down and slave the ailerons to go up. This is if this radio has the mix programing to allow this. If you go with an 8103 make sure you have all digital trim model. The mechanical throttle trim model will only allow very little trim on the throttle (glider mode). The new Futaba 9C series has the crow as a built in option. I'm sure JR will be following suit if they haven't already.
