Increasing throws?
whatever the mod do it a bit at a time. especially when moving the CG back as a tail heavy plane is a handful.
sometime when the flying season is upon us in NJ I plan on doing an article on converting a trainer into a "second plane" including moving The CG and increasing throws.
right now the Avistar trainer that I plan on doing this to is waiting for a test flight for another article so if it survives I will be using that.
