My 69 206 had a max deflection of about 30° on the flaps, it is R STOL and at one time was on floats, because it is placarded as no more than 30° of flaps on floats I think perhaps someone just went and adjusted them so they could not go to 40 degrees.
I had a mechanic try and adjust them to 40°, you could only get them to 37° and then we realized they would not retract all the way. The plastic cam on the flap switch is a little worn and the thought was that replacing it might help the flaps go to 40°.… But as I was looking at it and playing around, both of the micro switches on each end of the cam engage and disengage fine I’m wondering it other adjustments might work; I noticed that none of the limit switches engage in the wing (when I manually depress the “up” Micro switch on the flap switch it moves the flaps to about 37 degrees).
My question is, would it be OK to always have the limit switches in the wing engage, that way they would be the limiter of travel and not the micro switches on the flap switch. If this is kosher, I think I could adjust the follow up cable and micro switches to give me more deflection while still not triggering the opposite microswitch on the flap switch. … if this worked the only thing that would be off is the pointer for the flat position by the switch?- but I think this is adjustable?
