Default JR10X Flap programming problem

I'm sure there's gotta be an easy way of doing this, but I'm drawing a blank....

When the flaps are controlled by the left slider, I have flaps up with the slider fully up, and down 65 degress with the slider fully down, and I'm using 100% travel volume either side of neutral.

If I try to switch to using the "land" switch to activate the flaps (using function 66), and I disable the left slider, then I can get intermediate & full flap OK, but he flaps won't go up. The problem is that servo travel when using the switch in the flap program is from 0 to 100%, rather than from -100% to +100%. Using the full amount of available subtrim, I can get about -20% to +100%, but I haven't found a way of getting -100%. Is there some way of doing this within the flap program, or do I need to abandon this prog and just use P-mixes instead ?

(I could change the mechanical linkage to avoid the above, but I'd rather have the mechanical advantage that comes from using as much of the servo's throw as possible, rather than limiting myself to hal travel.)

Thanks in advance for any help you can offer.

try using your subtrims to bring flaps up

Already did - per my post: "Using the full amount of available subtrim, I can get about -20% to +100%, but I haven't found a way of getting -100%. ".

I usually take the servo horn back off with the switch in the up position and physically move the horn to the flaps are in the full up position with all of my sub trims zeroed and then start my adjustments. This is not uncommon to find that when you use the slider you have to reajust your linkage when you go to the switch.

Doing it that way does not let you use full advantage of the servo though, because you are using only HALF of the servo's travel and hence half of it's power.

For now, I have simply worked around this by using a flap->flap P.mix activated by the land switch being in the up position, but I've gotta believe that there is a cleaner way doing this. The guys at JR no doubt understand the importance of using as much of the servo travel as possible, so surely they'd understand the limitation that is imposed by having prog 66 use only half the travel ...

I don't own a 10X but I seem to remeber having this problem before. Try a P-mix mixing flap to flap on one side of nuetral.


Ahh, never mind - you thought of that
