Default DX7: easiest way to program dual elevators and ailerons?

I am in the finishing stages of a plane with a servo on each elevator half and aileron. What would be the easiest way to program this without using Y harness?


Thanks

Mike Mc put the instructions in this post on RCU http://www.rcuniverse.com/forum/m_48...tm.htm#5269071
This works perfectly on the Spektrum DX7.

Hi Guys,

I have checked both the listed setups. I am sure they work fine when using the AR7000 rx with an aux2. They did enable me to disable the flap switch. However I am usinf an AR6000 rx in a small EDF with split elevators. The onty open channel for the left elevator is the gear channel and p mix 5 elev-gear. This works unless I manage to hit the gear switch witch results in the deflection of the left elevator, NOT a good thing. Is there some way to inhibit the gear switch?

thanks
John

I had the same problem (needing the gear channel) when I put a 6200 rx in a trainer I keep around. I found a post Danny had made some time ago saying to set the travel limits for the gear channel to 0% in both directions to disable the switch.

It works great!

Thanks Zeeb,

When I tried that I only got about 50% down travel on the left elevator half [&o]

Did you set the travel limits for the slave channel in the mix?

Zeeb,

Yes, at 100%/100%. I still need some travel set on the gear channel to get full deflection. That amount will still show up with the operation of the gear switch.

Well even after monkeying around with the geometry on aileron linkages (that's what I needed from the gear channel), I have 83% on one side and 119% on the other one. I think this stuff can go all the way to 150%, but you can/will have a problem if set there and need or have some sub trim dialed in.

If that doesn't work, you'll need someone with more experience on this radio than me. I just bought it recently to play around with on my smaller models until my new X9303 gets here...

Thanks again Zeeb,

I have a setup I can live with now. Since I was not using rudder I plugged the L elev into the rudd channel, set p mix 5 to elev-rudd, rudd travel to 0-0, offset to position the L elev to neutral and am happy with that. No action from the rudd stick or the gear switch. Everything worked OK the other way until Murphy flipped the gear switch. This takes Murphy out of the equation.
