I have been busy at work and not had much time to work on it. I am up to the point of getting ready to put the tail hinges in. When using the 160 and an 18x6 prop does anyone think I need to add any right thrust to the mount. I am also going to seal both sides of the hinge line, although all the ailerons all have between 1/32 to 1/16 inche of a gap. But better safe than sorry.
