Servo Operations

I think I might be missing something, maybe a brain black-out (get a few at my age.. :lol: )

Flying wing, two Futaba servos pulling on elvons. The issue I have is, push stick forward elvons go down and pull back to climb. Good! However, left aileron stick makes aileron go down instead of up. In other words turning left actually means right. Reversing servos in delta wing mix reverses elevator too. Am I missing something?

Either that or I'll have to change servos for Hitec/Spektrum who by default rotate in the opposite direction.

You should not need to change servos. I am pretty sure futaba servos are used in flying wings.

This is a transmitter programming issue. What type of transmitter are you using?

Try swapping them both over in the rx plugs ,ie if left servo is pluged into elevator.plug the right one in instead and plug the other into the other channel ,ie rudder if using flapperon function.You may have to reverse the elevator though .Its fun ,but im sure you will get there.
I had to do this the other day when using a pcm 9x 2 and an orange rx.Worked for me .

Good luck,im sure it wont be the servos.Just the above or a program issue.Hope this helps

Ian is bang on the money, just swap the 2 servo plugs over at the receiver, then reverse as necessary, this will solve your puzzle.

I have tried swapping leads and then reversing. I'll do it all again though just in case I am doing something stupid.... :lol: Strangely I can usually solve a grander problem but when things are simple..... :silly:

Sorted! There were two other switches I missed. With device set at Delta wing two switches become LEV REV. Just reversed these two and presto. What a numb-nut! :oops: Thanks for your inputs. I think I am succumbing to ageism.... :lol:

They are called craft moments - can't remember a fxxxxxxxxg thing. i have plenty.
