I've got a hotliner sailplane I'm getting ready to put in the air. Another club member had one like this and said it was hard to get it on the ground. So, I thought to myself - I'll use the flaperon mix available in my XF421 TX to help with that problem.
Uh, well, right, maybe. dang, that's a problem in itself !
Basis for discussion:
Ailerons are mechanically and electrically centered before flaperons enabled. Left aileron = aux channel, right aileron = aileron channel.
For those not familiar, the ~ symbol is used for 'approximately".
Enable flaperons in TX and results are:
Both ailerons are down ~same amount.
Move stick right - right aileron moves up to ~neutral. left aileron does not move. Move stick left - right aileron does not move. left aileron moves up to ~neutral.
Flip Aux switch to other position:
Both ailerons are up - left more than right.
Move stick right - right aileron up slightly. left aileron down but not to neutral. Move stick left - right aileron down past neutral. left aileron up slightly.
Interesting is 'travel adjustment' ! In normal mode, I have +/- 100% on both Ail and Aux. But when I turn flaperons on, I get +/- 100% on Aux, but get +100% on Ail only at full left stick !
I spent an hour fiddling with ATV and electronic centering, but never got equal travel on both ailerons, or got rid of end binding on the left side.
So, from which position do I try to neutralize and set travels. I'm looking for 'spoileron' operation, which should be merely the opposite of 'flaperon'.
Anyone out there with an XF421 with ideas?????????
