I did finally decide on an AOA/LRI and needed to install it prior to airwoirthiness inspection. I wasn smart enough to get pictures as i built the sensor, or installed it under the LH wing. Sorry 'bout that.
1) Pulling..pushing..cussing...the sensor tubing thru the wing was an PITA, but with the assist of a good old twisted pair of bailing wires I was able to suspend my frustrations. Here is the result...tubing in the cockpit.
2) Here is where I put the sensor. The info I have from several places in the interweb indidated to place it 15-30% aft of leading edge, well outside of prop blast, and begin with an angel of roughly 56 deg...maybe 60 deg? It will be callibrated at the onset of flying status with the first stall or first landing speed and note where the LRI needle points. the meter is maganahelix II..about $60 with shipping, 3/16 ID plastic hose. homemade sensor with two 90deg holes facing ointo the relative wind. No electricity needed..totally independant fo any other A/C system. Nice! Other friends have them and say they pretty much fly landings with them as primary instrument. Not sure I will do that for a while! The principal is very good, however. Cheap too!!
