Brief Description:  Reverse pitch control and clean up

During the last sytem check out with the tru trak servo opertion, it was noted that the pitch servo operated in reverse. The harness came with a loop on pin 1 to 2 for ccw rotaion on servo being an up pitch action. This is opposite of what I ineed. So I needed to see if there was the wire loop in this pi out and then either add it or cut it depending on how this end of the harness was prewired. Turns out after I removed the dsub fromn the back of power head and dismantled that I realized that I needed to just cut the wire.o and capped the ends, reassembled the dsub body and attached to test. Test proved successful this time. I then raised and lowered the tail to check for oppoise response in the elevator to level out. This was done 3 times to confirm and Im satisfied that it works as required.

installed a couple of adel clamps for th right upper spark ignition wires to secure to the engine mount.

Closed up the access panel and then cleaned up all the dirt and garbage that has collected fwd of the wing spar in front of seat. This is kinda hard to reach but i got it cleaned up.

Rest of the time was spent cleaning the work bench areas up and organizing.
