I also found the standard electric flap system lacking so I designed and
built this simple modification. The attachment shows the mechanical and
electrical components and circuitry that allow a momentary contact switch to
get the flaps moving and stop at the next position going either direction.
A "traffic light" on the panel shows red for "full" orange at "half" and
green for "in motion."
Since I am not yet flying I can't confirm that the notches in the rod are
located precisely for half flaps but from static tests they are about right.

Hi,
I've been wondering about the electric flap mod for a taildragger. Ignore
the 'taildragger' bit in this case as it's actually the standard system
fitted to the tri-gear.
I like the simplicity (and have all the parts) to modify the mechanical mono
flap system and then just have 2 indents on the flap arm guide (half flap
and full flap). This to me is a cheap, lightweight and fail safe system.
The electric flap mod is interesting though.
My question is: Do you operate the rocker switch for flaps up or down and
then look at the markings on the flap and then stop operating the flap
switch when the flap is 'about in the right position'. Or, is the system
'Cessna style' where you hit the switch and wait while the flap moves to
half flap and then hit the switch again if you want full flap?
If the system is of the former description above then I kind of think that
the electric flap is just another distraction in the circuit if you are
operating the swicth and looking out to see when it's reached the correct
angle versus just moving the mono handle to the correct indent.
Have I understood the electric flap system correctly or is it more slick
than I think?
Thanks,
Phil
