Thanks for the info. If I am understanding correctly, I should be checking my old Senior to be sure that angles/locations of the stabilizer and the wing are in fact, built to the same specifications as the one that I'm currently building?Since my old plane has much less down thrust, it may be a possibility that whoever built it years ago, might have altered these areas to allow/compensate for the different down thrust?

If everything else is the same as designed, what exactly would be the benefit of removing so much of the down thrust designed into the plane? What difference would it make in the flying characteristics?

thanks again, just trying to wrap my head around this concept before the CA dries!
