Default Stab Incidence

camss69 - At the very least you should block up the plane and check the incidence of the stab, wing and the thrustline. At least you'll know for sure what you're dealing with. Sometimes things aren't what they appear to be. Your stab may be dead on.

amcross is right that if the number you posted is correct, then it's not cause for alarm. The problem is that trim settings will be speed sensitive. Usually I set up my dual rates to give me plenty of throw on high rate in case I don't have enough throw at the recommended rates. So far I haven't had a problem that I needed the high rate. I have had planes where I almost ran out of trim on a surface on the first flight.

Here's something else to think about. If you balance the plane slightly nose-heavy AND the stab has all that positive incidence you may need a lot of up trim. Don't sweat it, just be ready on the sticks. Get some altitude and get her trimmed. Land, make adjustments and have fun. :thumbup:
