just a note re the dx6i and mixing for flaps. flaps = aux, slave = gear. becareful after slaving the gear to the aux....because of the way the two channels operate independently. the gear switch does not seam to be able to be disabled with dx6i even after "mixing" to aux. the only way to disable it would be to decrease travel in both directions to zero...but with dx6i you need travel for"gear" in one direction for flaps. it is possible , therefore, to set mix up for flaps, but still operate the slave servo with the gear switch. depending on the setup, if you hit gear, you might overdrive the gear servo and fry it!. (like i did). what i suggest is setting up the mix without the "gear" servo plugged in at first, but just set it up by viewing it's range and direction of travel in the "monitor" view....this way you can make sure you set things up to operate properly without overdriving your gear servo( and frying it if its cheapo ds75 etc!). SO, if you only have 6 channels to play with, you can only operate one flap mix, and must therefore use a y harness for you two aileron servos. if you use a y harness for your flaps you need to have a "servo" reverse module to set it up for symetry for both sides.note: you can't just flip the servo arm and keep servo symmetry because the arm would be upside down....ie both arms need to travel in same direction for flaps unlike ailerons....using "reverse servo" in the transmitter only changes direction of throw as long as servo stays in same place, you cant just flip it in this case.....

i'm just rambling about this because the dx6i manual is crap, and i fried a servo and wasted hours figuring everything out.....i think the best answer is dx7 or bettter.

a further note to newbies like me: the values for "mixing" are the equivalent amount of mirroring travel you want from your slave vs master. kinda like dual rate/expo setting after you set main travel in "travel aDJUST " SECTION.

hope this helps somebody,,,,,on the other hand maybe i got it wrong? but this is what i experienced.
