Ahhh...yessss.... the cause for electric-flaps....
I slip my arm free from my fixed-position shoulder harness to deploy flaps on approach while I am still letting down into the pattern. I then slip back into my harness for the landing.
STOWING the flaps in the retracted position is NEVER a problem...as the button can be released ...the flap handle lowered to the retracted position, and my hand slid down toward the trim-wheel to pres against the flap handle to finally "latch " it into the locked/stowed position.
Prior to departure..... before beginning my takeoff roll... I do the same: Slip my arm out of the harness, set the flaps for takeoff, ....slip back into the harness...and take off. After lift-off, when safely away and into the climb, it's easy to release the button again, let the flaps retract (due to air pressure) and when the handle is again in the stowed position, I can easly reach the handle close to the trim wheel, press down and hear/feel that satisfying "click" as it locks into the flaps-UP/Stowed-handle position.
I appreciate the EZ Flap developer's enthusiasm for his product, and I congratulate him on carrying his idea to fruition/market. [edit[
In any case, I don't find any real need for his product. And it's ugly, un-original, and expensive. No safety feature can I discern about it. He seems interested in developing other aviation products as well, however.
