Great timing. Finished my 4th flight today and then find a "grounding SB". I have the aftermarket billets, the pins go way past the fiberglass, the doors "lock" nicely, and my warning light system works (they don't go out until the latches click and they are the "push to test" type). So I will continue to fly until our community comes to a more settled opinion. In terms of the aileron trim: 4 flights is not a lot of experience but on today's flight I flew the right tank down fairly low (to make it easier to recalibrate the floats) and I had to use the trim to get the wings to stay level hands off. Now a few questions: My elevator trim works well (both equally neutral and both sides stay that way at cruise speeds) although my elevator horns are up about 1/4 to 1/2 inch on each side at 145K, -3 flaps, and level flight. (Looks like Tim's picture on his site). So I think all that is good, but when the trim is neutral the EFIS trim indicator is way off the neutral (centered indication). I've gone thru the set up procedure twice with the same results. Any advice on how to "square up" the indicator? Even the aileron trim indicator is off a bit but I really have not looked at it with even weighting (fuel and front passengers). One last question: Have about 7 hours on the engine (Mattituck with 9:1 pistons, LightSpeed on the top) and have been anal about the break-in: only 20 minutes of ground time and always 70-75% except for the 4 landings. OAT between 0 and 30F, CHT's never above 365 and oil temps at 170 on climb out and low 160's at high cruise. And I am not burning any oil!! And it still looks as clear as when I first put it in. Should I just shut up or am I missing something? Jay Rowe

Newbie here... but still have ideas.... I would put a blockage of some sort prior to your scat for the oil cooler... get that oil temp up to 180 to 190 range. Insure that it's burning off any moisture/condensate. I made a butterfly valve for the rear of the plenum on mine, and it works great. Open all the way, I see numbers like yours, in the low 160's. but a little pull on the butterfly valve, 180 to 190. Other than that, keep flying. Where are you located?

You may be broken in, but I would go to at least 15-20 hours doing
what you are doing before deciding to change anything, Perhaps even
25.
