what size prop on your saito 125? ALSO what was the amount of thrust u put in the firewall with the 125? I know this is really really stupid but here it goes, how do i measure the angle of thrust to make sure it is 5 degrees? i have no way to tell.... And to add it do i just put washers behind the motor mount?

MIXMASTER, how do i fill the hing gaps? I think that is the gap between the ailerons and the wing, the elevator and the back wing.. is that right?

I am so nervous to start building this thing.. I always mess up something. I may just let it sit in box a few more days....
