Automatic spoilers/spoilerons

[G550Ted]

With thanx to Mike B. for his guidance here are the mixes and switch to accomplish SLOW spoiler/spoileron extension and retraction. The "Auto" part is that the spoilers/spoilerons (when selected to extend) are made to also retract whenever the throttle stick is greater than 1/2 throttle and extend again when the throttle is moved to less than 1/2. I have set a delay of 1 second for scale purposes and to allow some pilot reaction time in the event there is any pitch or roll result from the spoiler actuation.

Love it, thanks for posting Ted, I changed all the slows to 4, I like it slower like that. Hopefully I willl get to try it soon.

I actually have this mix, funny seeing it on here, however I have it slightly different, spoilers are activated manually with ELEV D/R switch, but retracts automatically(slow) with +60% power for a go-around. It also retracts automatically when any stage of flap is extended. The flaps also retract to zero in a go-around,however, as you can see flaps and spoilerons are'nt used together since the flaps have authority. Differential aileron travel is also comensurate with flap setting.

What I still can't seem to get is flaps retracting to first stage instead of zero during a go-around (too much initial loss of lift when going from full flaps to zero)

I don't think it is a good idea to slow the spoilers on a situation of go around.. If you do a go around it is because something went wrong and you need all the lift you can get, plus need to increase speed quickly. spoilers produce drag and destroy lift.

Just my 2c maybe I'm wrong..

absolutely correct ...I will do some touch and goes and try it out to see if it causes any problems ...and besides I dont have it running very slow ...it literally takes less than 2 secs to retract ...but good point to consider ...thanks .

Maybe i'm saying a foolish thing, but is it possible to delay ony the flap/eron down sequence

Not all go-arounds are initiated low and slow. For me, at least, it seems that most of mine are due to being too fast and/or too high on an approach. For those times when I do have to abort when low and slow, control is more important than a small delay in the slight reduction of drag/increase in lift at that point. Like the addition of power for the go-around, changing the configuration of flaps/flaperons/spoilers/spoilerons/whatever should be at a reasonable rate so the pilot can adjust for the changing aircraft response. In the end it is whatever works for any particular model and pilot.

Certainly. The delay function has separate time adjustments for both down and up.

I still think that a spoiler should be retracted fast..

do you think it is possible to use the aileron as flaps and vice verse in a mix with two servos. maybe the three pos. switch 0 ailerons switch 2,3 flaps with maybe some aileron but limited flaps over aileron ?

Of course. Easily done.

can get more help then easy i know easy when it slaps me in the face

[Rob Thomson]

Do you use companion?

There is a model wizard that will create it for you.

If no joy... I will post an example. But may have to wait as am not at pc for the day.

i'm in no hurry, don't think i have companion down loaded. companion is the better of the two?

[Rob Thomson]

Depends on your firmware.

OpenTX is best for companion.
Er9x for eepe.

But companion will enable you more or less to work with er9x too.
