Building FT F22 (not the mini) using my Spectrum NX8 and the Spectrum 6 Chan receiver. There are menu options for Talerons and Elevons. Can't get both (tested good) servos to work together. Help?

If you are using ailerons, you want the tail to use a Vtail on the tail, which will use rudder & elevator sticks.

If you are not using ailerons, you will want elevons, which will use aileron & elevator sticks.

Great looking plane
Did not fly well. Three launches with cog set per plans showed a lack of pitch control. I don't like the hinges made with tape (too loosey-goosey for me) and the extremely long push rods. Will use a different hinging on the rebuild and move the servos closer to the elevons.

Agreed, I'm not a fan of FT hinge or push rods.

I do use a taped hinge but mine are far more durable. I tape the top in the normal fashion, then hot glue the back side, smear it out in the normal fashion. The tape the back side, use a hot iron to reactive the glue. This sticks the tape to the back side. I've never had this hinge fail.

I use the wire from utility marking flags for pushrods. Far stiffer than FT.

The FT wire is usable, you just need to support it every 3 inches or so. Utility flag wire can easily 6 inches without support.

Another trick: critical direction of surface is a pull. In other words, if you are running up trim, it needs the control horn on top to be a pull for up. Powered models need pull for right rudder, torque will make it turn left using standard rotation. Ailerons need pull for up. Ueah I know that shows the control horns, but you'll thank me later.

If it's a pull, you can get by with string and no stiffening.

So that you don’t have to move the servos you can add a piece off carbon rod or skewer to the push rods with a dab of super glue and heat shrink near each end. Then you won’t have to mess with possibly adding ballast weight to maintain the proper CG.

F22 2nd build went well. Moved servos to the tail. Hinged with pin type hinges made from string stiffened with CA glue reinforced with a single layer of tape on top.
1st flight required considerable back stick for level flight. Adjusted both elevons like it was a flying wing that needed reflex. 2nd and 3rd flight was beautiful!
7 minutes on a 1350ma 3 cell, B motor swinging a 9x4.5 prop. Batts had 30% remaining.
Modified the hatch to swing open.
