Flap/Aileron mixing with DX7-SOLVED THANK YOU

       Remove this ad - become a site supporter!
Trying to program my DX7s with an ar710 receiver for use in a a 4*60 with four wing servos is making me feel old. I would like to have the flaps work in tandem with the ailerons until I flip the flap switch. Then they should work as independent flaps. Right now I have the flaps and ailerons both working properly independently. I thought I would only need to create 2 mix settings to each have the appropriate (right or left) flap mixed 100% to the appropriate aileron. I assigned both mix 1 and mix 2 to the mix switch. I set this up but nothing seams to have changed. Am I on the right track?

Re: Feeling Old Needing Help

Hey there... I'm no expert and trying to do it only knowing how many servos is tricky and there are other variables like which orientation the servos are in, etc. So, take this with a grain of salt, but you can try this config from my DX7s I just tried.

Note: I have NOT ever flown with this, purely played with it on the Tx and watched the 'Monitor' levels / display while mixing. So, be sure everything is working before you fly as always and this is just an as-is, no guarantee kind-of-thing .

Anyway, I think the thing is when you have AIL mixed on MIX 1 and MIX 2 to LFL and RFL respectively, the SW can't be the same for both mixes - I don't think. Don't quote me on that. So I messed around and with Mix 1 on the GEAR switch and Mix 2 on the MIX switch here's what happens:

- if both MIX & GEAR are down (= 0 ) then flaps are flaps switch only controlled.
- if only MIX is up (= 1 ) then both LFL and RFL will move in the same direction as each other, but in the opposite direction to the ailerons.
- if only GEAR i sup (= 1 ) then LFL will follow the ailerons' signal and RFL will be exactly opposite
- oddly, if both MIX & GEAR are up (= 1 ) at the same time then LFL stays rock solid and RFL will move in opposition to the aileron input. (I don't think this is very useful )

Anyway, I don't have any more time to play with this... sure someone else who's messed with mixing more than us will weigh in, but at least this is another idea to help the thought process.
