Mike,
I=99m not sure there=99s a defined standard size and location f
or the trim tab,
therefor there wouldn=99t be a defined range of motion. (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.

Thanks very much for the help
Inspector was concerned that my range of movement was too large and that it
may not be controllable in case of trim "runaway".
I have a Ray Allen servo
Will change bracket and reduce range of motion and if not enough increase
it later
Thanks again
Mike
