So.... in between family stuff this weekend, I figured I'd get that hangar 9 arf flying again. I just wanted to fly something. It's been since November. Lol. All the repairs, then making / modifying a venturi to the correct size... got everything assembled and went to test run it. I had to free up the engine, it's been sitting in a box forever. The engine knocked like crazy and the prop shaft felt loose back and forth.... found out why. I found another engine and test ran it, but I'll need to switch the venturi. Oh well.
