Ok so heres what I ended up with:
(DX7/AR7000)
R aile on "Aile"
L aile on "Aux 1"
R elev on "Elev"
L elev on "Aux 2"

Using mix 5 and slaving the second elev servo on aux 2.

everything goes in the right directions and seems to work ok, but there is something odd happening with the aile; when I apply full aileron (R or L) the one going up will top out before the one going down. it does this in either direction. the aile going up always tops out first. I have messed with travel limits and sub trim but nothing seems to help. weird.

also worth noting is that the servos that come with this plane are total crap. centering is pretty random and all over the place. especially one of the elev servos. I think I'll replace them but all of the sudden this "rx ready arf" doesnt seem like as good of a deal. oh well its still a pretty cool plane and if the wind/rain would ever stop I might get to actually FLY the damned thing!
