Barn door flaps on Tundra w OpenTX

[Raglanmatt]

Kia ora all. I have 3 pos flaps running on a switch using a curve and delay on Tundra for general flying. I want to add a second switch to barn door the flaps instantly. I've tried adding a second line on the same channel with the switch adding a weight of 200. Both lines work fine on their own but when I put them both onto the same channel only the bottom one works. I've tried changing the add / multiply /replace lines but that didn't do anything. I'm doing all this in mixes with nothing in inputs. Any ideas? Cheers, Matt

You could try using flight modes..

(I assume by barndoor you mean flaps at essentially 90 degrees down to the wing chord.)

But if you already getting 100 on your channel monitor for 'normal' down flaps, you can't get more unless change the OUTPUTS line for that mix.
This may stress your servo...even to the point of stripping gears.

If that is the case, you must reduce the weight on your 'normal' flap switch and make mechanical adjustments to get more flap movement for smaller servo movement.

Then your second mix for barndoor can have an effect.
Add should do it, bur replace could work also.
