(For example, I added springs to my up-elevator to allow more nose-up (slow flight) trim because my trim tab was not effective below about 90-KIAS.) Could you try showing the inspector the build manual and that it doesn =99t specify the range of motion? That build manual is very, very poorly written. -Doug Crane N302KM On Mon, Sep 18, 2023 at 17:47 wrote: > I just had the inspector here and he wants a spec on the range of movemen t > for the elevator trim tab.

I have a Ray Allen servo Will change bracket and reduce range of motion and if not enough increase it later Thanks again Mike On Wed., Sep. 20, 2023, 7:33 a.m. Doug Crane, wrote : > Mike, > > I=99m not sure there=99s a defined standard size and location for the trim > tab, therefor there wouldn=99t be a defined range of motion.
