@mayan - I run an old school JR X378 (FM) and an FSi6s (quad Tx) - the i6s is a nice rig but does not have any pre mixes - I set up the Elevons tonight (same as my i6s thread) works well - Elevons are just done with two mixes between the aileron and Elevator channels - my throws are a bit unbalanced, so I need to do some tweaking there and set them at the recommended 12 deg - CG to check then it will be good to go!
I use my JR on the Pheonix hybrid with a few more tricks programmed (that I am yet to use)
I am lining up for a Jumper T16 (watching for when they release better sticks) - no rush!
