I have this in a E-Flite 1.2m T-28 for use with my X18S. Works great and I'm using all 8 channels (plus 9, 10 and 12 for stabilization functions). I use the stabilization when it's gusty. Channels are AETR, 5 is flaps, 6 is retracts, 7 is nose wheel steering so I can trim without effecting rudder, 8 is nose retract since it's a replacement which retracts opposite the E-Flite mains, so reversed channel 8 for that. Love the flexibility of extra channels!
