The elevators and the rudder have trim tabs shown on them. Are these abolutely necessary, and what is the best way to mount them? I would imagine that epoxy wire into the trailing edges and into the trim tabs so you can bend them slightly, if necessary...

I recently received the set of Flying Models plans for this plane (similar size) and there is even less detail on these than the MAN plans. I think I will make the outer panel wing ribs using the sandwich method as described on the MAN plans. One question I have is the way they show the tip rib in relation to the root rib. Because the outer wing has a swept back leading edge but a straight trailing edge, shouldn't the trailing edge of the tip rib template be even with the trailing edge of the root rib template? I discussed this with a friend and his only thought was that it would be easier to bolt the stack of rib material together and hold them in place more securely. I can appreciate this, but wouldn't the airfoil be different if you did it the way the plans describe vs. if you kept the trailing edges even?
