Steve,

I made an aluminum flap to replace a portion of the rear flat part of the ES nose gear fairing. Hinged it to the fiberglass fairing and mounted a Mac 8A servo motor to the cross tube of the engine mount. Connected the motor to the flap with a clevis linkage and set the travel to shut off when the flap closed. It works pretty well with the on-off-on switch. I have timed it for full travel and can set it by the clock to whatever opening I need for the conditions. Not a big project. I am attaching some photos. Hope they help.

How did you make the electric flap. I need to make some cowl exit space
myself ( I have none except for a shark gill on the side and a couple on the
bottom). I'd like to make one under the rear of the cowl that would move up
and down. If I get my exit area straightened out I think my oil temps will be
great.
