I'm just finishing up on a Biplane and have run into a situation. I have the bottom ailerons hooked up to ail 1 and ail 2. The upper ailerons are hooked up to flap 1 and Flap 2. In wing type I have selected 2 aileron channels and 2 flap channels.

The issue I am having is that although the flap channels are mixed to J1 the dual rate and expo only work on the aileron channels and not the flap channels. Is there a way to fix this?

Dan, there are no other available channels, the flap channels are proportional. I have the 4 aileron servos, dual elevator servos, rudder servo, throttle and dual power inputs. That makes all channels on the Optima 9 RX taken and I even need a Y connector on the rudder for the second power input. The issue as I see it is that having the Expo and D/R working on all 4 servos was missed in the software version that is in my TX. I was hoping a Hitec rep would chime in and let me know a software version that had the correct programming or if I had the TX in the wrong wing mode for this. The only work around that I can think of at this point is to use a pair of matchboxes and Y the upper and lower ailerons through the matchboxes so I am able to dial in centers and end points exactly.

I tried to assign all 4 channels to operate via J1 and it affected one of the elevator servos. I was in the dual aileron wing type though. If I could ask you to give me a bit more detail in setting this up it would be much appreciated. I at this point would like to know what wing and tail type to set to and what channels for each aileron and elevator servo. Just looking to save some time here as this new airplanes contest debut is in 3 weeks.

I was able to figure it out using the clues from your last post. I set wing type to single aileron and tail to ailevators. For ailerons I used Ch 1, 6,7 and 8 all set to J1. All functions as I need now. I appreciate the help.
