Thanks Tracy .. I basically copied the approach that Phil used. (thanks Phil) But here's another pic if it's helpful. Regards, Dave

Also be careful when measuring the travel on the Ray Allen Pos sensors. There is an amount of travel that is dead at both extremities. I measured mine with the LED indicator wired and activated. That is why I have the three holes for fine tuning so as soon as the flap starts and stops moving it is imediately visible on the indicator. You probably don't need to be so precise as you can always look out the bubble but I thought what the heck, it is there to do a job so it may as well be calibrated properly.

 

Hope I am helping.

I added a picture to the bottom of my previous message. I don't know why it is not appearing. Here goes again.

Hi Wes & Lurlene Below I have copy and pasted a page from my website.  http://www.mykitlog.com/ch601xl If you look very closely you will see that I drilled three holes in the flap arm to allow me to fine tune the travel required for the sensor. Do yourself a favour and use a cobalt drill to drill these small holes in 4130. If you cut a notch near one end in a piece of card or paper so that it sits over the flap tube, you can mark the back edge of the flap arm onto it. Then apply full flap and mark the back edge of the flap arm again. Take your piece of card to the bench and mark up the lines drawn in 5mm incriments and find the correct travel. Then you can get back up inside the belly hatch and mark and drill your holes. This system will save your back   Made a bracket from .025" to mount the Ray Allen POS12 sensor on. Used pushrod and clevises designed for large scale model aircraft. Pushrod is a 4-40 threaded rod with nylon clevises     Regards Phill
