Yeah, I think you are done trimming until you get more confidant in the power plant. I still have to wonder if you are getting any air over the motor. Even with holes in the spinner back plate, the opening in the front of the fuse is completely blocked off by the spinner. You get no prop thrust through the holes, and the airflow can't change directions around the spinner, then the prop hub, then turn left through the hole. Air is a liquid that takes the path of least resistance, and you have no direct path for air to get to the motor. All you may need to do , if you can, is pull the prop adapter forward, and make a gap between the back plate and the front of the fuse, and see if that helps the situation. You have a better chance of air flowing in the fuse opening there than getting through holes in the back plate, in my opinion. Even with the stab warp, the airplane was looking pretty good, especially at the slower lap time.. Hope to get out some next weekend and just fun fly and we can work on it some more.
Type at you later,
