I installed the regulator onto the naca and put the airplane back together. 2 separate test flights show the idea worked! I need to do a nice long flight to compare oil temps and I may do that tomorrow, but so far they look unaffected by the mod :) 14.3V solid through the whole flight. Now to test those heaters again and put some strain on the alternator and regulator. If it lasts 30 minutes with no issues i'll call it a success. :) Hopefully another flight tomorrow ;)
