Todd:

I have 3 aircraft programmed this way on my 9C, the method works perfectly and does not use a valuable multi point mix. You don't need to set the centre position, takeoff flap is set by varying the end point with the switch in the UP position and adjusting the linkage to set the zero flap position.

For example, 75% (with the flap at zero when the switch is UP) may result in 25º in the centre position. 80% may result in 15º. In the DOWN position, 90% may result in 45º whereas 100% may result in 60º.

These are speculative numbers only, the actuals are dependent on the flap horn and servo horn positions. Hence one has to play with the endpoint adjustments to acheive the desired movement(s). The method provides three definitive positions that are acheived by setting the UP ond DOWN endpoints. The CTR position is simply a function of the endpoint adjustment of the UP position.

Give it a whirl, you may like it!
