Test of operation was successful. Will need to spend some more time setting up the transmitter to get a small deflection at mid switch.

Left servo attached to glued in plate. Dual servo arm was reduced to use the middle hole for proper flap deflection.

Right Servo attached to glued in plate. Used dual servo arm for more stability using middle hole for proper flap deflection.

Had to use a reverser off the Y cable to get the right-hand servo to move in the correct direction.

Servos installed on 1.4" basswood plate raised another 1/4" on spacers. All glued to the ribs and to the top skin

Same goes for the right flap. For a while, I thought I'd never get here. It has taken weeks to get this flap scheme setup.

Cut servo mounts from Aluminum angle. Will change screw down holes from 2 to 4. Will install plywood base pad between ribs then screw down servo to it.

These two receivers allow for 16 PWM channels, could also go to the X-Bus system if I wanted. Tested channels 9-16 and all worked as advertised.

Radio setup. JR 28X and new RG812BX receivers with the Smart-Fly boards. These boards provide the power and isolation to the servos. This model also has the ignition switch for the motors. Also, supplies automatic power switch over if one battery goes low. The reason I really like the Smart-Fly board is that if a Servo shorts the board just shuts down that channel and the receiver is isolated and continues to operate.

Flap deployed to 45 degrees. Looks pretty good, will find out when servo is installed. Looks like it will take a longer servo arm to get full deployment.

Will close up the right flap tomorrow and glue in the servo attach point in both flaps. The attach point has to be redesigned due to fowler flap setup and will take some time to figure out. Would like to get servos mounted and linkage installed to test the flap operation.

Patches on left flap top side. Learned a lesson to use one drop of CA for temporary attachments. I used too much and had to sand them off and or repair the skin that got pulled away.

Better photo of small square. A 1-inch angle is actually square. CA used to temporarily hold the hinges for a test. Cut the flap loose and it all works with no binding.

Here is the final setup. Two small squares (1x1 angle) on each side clamped to the spar and a perfectly squared jig to make the other hinge parallel. I first set one hinge perpendicular to the spar with a larger square and then set the parallel board and clamp it in.

Left hinge glued in and right side just setting up against the jig. I will measure across then hinges to ensure that they are pararll

A rear view of hinge clamped in place. I used CA to temporarily set the hinge. Side supports will be epoxied in.

The side locator is set against the spare to set the correct angle to the flap. Here the hinge is clamped in place to the jig.

Jig in place. The crossbar at the rear sets the plum, perpendicular to the skin, and the side locator is removable so it can switch sides for left and right flap locations.

These are the newly cut hinges that reach the skin in both the wing and the flap. Each one is custom fit to its location on the left or right side of the flap.

Just another view of jig pulled back. More work to make it work in both left and right hinge locations in the flap.

Side view of the jig. This jig is as close as I can get to 90 degrees to flap face and plumb to the skin.

Vertical view of my jig. It is exact to the same size of the actual hinge in the wing. Some more work will be needed to get a placement for the hinge in the flap. I should be the exact center of the gig. I'll see if I can find center and make it usable to make the location.

As Sam showed, I went ahead and temporarily glued in the flaps. Also shows how I butchered up the flaps and how much work it will be to get the back in shape.
