Throttle mix

Post by Suncoaster »

I have been given a ASK-21M glider with a motor on a retractable pod. Currently I have the pod controlled by the gear switch and I have a mix on the throttle that will not start unless the pod is up and that works fine except today I had a problem on final and I was not quick enough to raise the pod and then throttle up before I had a hard arrival off the end of the strip.

Can someone suggest a mix that would use the first quarter of the throttle to raise the pod and then act as a normal throttle from then on. Everything I have tried to date does not work, I have tried a throttle curve and several variations of that scenario to no avail. :( Any and all help appreciated

Is the pod controlled by a servo on another channel?
How long does the pod take to move up and down?

I should be possible to make it automatic, e.g. throttle down - wait to allow motor to stop, retract pod. Throttle up, if pod down, hold off throttle, raise pod, wait to allow pod to rise, enable throttle.

Hi Mike, yes the pod is controlled by a separate servo connected to Ch 5. It takes approximately one second to move in either direction.

Here is a starting setup (using channel 3 for throttle):
CH3: +100% Thr
R -100% HALF switch(L1)
CH5: +100% FULL Switch(L2) Delay(u1:d0)
CH09: +100% CH5 Delay(u0:d1)

L1: v<val CH9 98
L2: v>val Thr -99

When you open the throttle, channel 5 raises the pod, and, 1 second after starting the raising of the pod, the throttle channel outputs the selected throttle setting.
When the throttle is reduced to -100%, there is a 1 second delay, to allow the prop to stop turning, then the pod is retracted.

Thanks Mike I will give this a try in the morning.

Edit. Worked like a charm, :D just had to change the timing slightly. Once again thanks Mike.
