KR> Electrical Power Management
Always had a problem with my GPS in my KR-2 not operating on aircraft power, but ok on internal batteries. Always made a note to trouble shoot that when I got a chance. Did not need GPS on first flights over the airport. Today while hooking up power for the new flap actuator, I found 2 each AN970-3 fender washers on the power control printed circuit board. One was laying loose on top of some components; no problem there, but some bouncing around could create some excitement. The second washer was wedged firmly between a grounded brace part of the power panel and the output terminal on the GPS power toggle switch. So, every time GPS power was switched on, the electronic circuit breaker would trip and no power for the GPS. Removed the offending washers and all is well. Have no idea how these two big washers got there. Stuff happens. So, have possibly toned down the level of excitement for subsequent flights. Sid Wood Tri-gear KR-2 N6242 Mechanicsville, MD, USA

Larry I misspoke. The unit I have is the Sport not the Pro version where you have to install pressure ports in the bottom and top of the wing somewhere between 15 to 40% of the wing chord. My question was where along the wing, outside the prop wash area, is the best place. Is there a problem with being to close to the wingtip or a fuel cap, does surface with rivets pose an issue? Those are the questions I have.

You want the probs in clean air as possible. However you will calibrate it to your airplane and that will take out all the variables.?

Both pressure ports on located on the single pitot assembly. You simply have to get the pitot assembly located on the wing to be properly aligned for cruise or as directed in the mounting instructions. As the angle of attack increases at slower speeds, the difference in pressure between the two fixed ports gives you a read on the panel. The pitot assembly looks exactly like the one installed on a friends RV10. Once installed, it was calibrated in flight with a simple procedure of doing a 5 degree nose up and down from level flight and then doing a stall. Yours will have its own specific instructions. If you don't have the procedure for your assembly, contact the manufacturer. Larry Flesner

Netters Has anyone installed an AOA warning system in their KR-2S? I'm looking for suggestions as to pressure port locations that anyone has used for their installation. I have a Advanced Flight Systems Pro series AOA that I want to use in my plane. All suggestions and ideas cheerfully accepted for evaluation. Pete Klapp, building N729PK, Canton, OH
