![]() But you still are better off with a balsa trailing edge cap.Īs you say they don't need to be as big as some suggest. You may elect to anchor the hinges at the rib locations and that isn't a bad idea. On top of this it provides you with a hard edge to bond the covering to instead of leaving it floating around or trying to stick it to something less suitable than a balsa cap.Ī dowel will both be heavier and not as stiff as a vertical balsa trailing edge cap which the ribs glue to and which the hinges anchor to. ![]() Or at best you'll greatly increase the load on the servo. If the hinge line is able to bend, bow or distort and the hinges get out of line then you won't be able to move the aileron. It greatly stiffens up the trailing edge of the wing and supports the hinge line. So if the model comes with a well known good reputation just go with the proven recipe and leave it alone.Īmish, you need a trailing edge cap, beam or whatever you want to call it at the hinge line. By replacing the "12% Florsheim Special" with a known better performer could end up with the model being too much for the newbie pilot when it speeds excessively at the slightest tendency to drop the nose. A model which does not like to speed up easily is actually a big blessing to a new pilot. Now those of us looking for ultimate efficiency may find this disturbing and be inclined to replace it with a "proper" airfoil. Most of them have fairly high drag when pushed to higher speeds. Any resemblance to a brand name tested airfoil is purely coincidental". To paraphrase the disclaimer at the beginning of a lot of moves "the airfoil shown is not of any particular type. The average flat bottom airfoil on most trainers is a flat bottom, some sort of circular radius on the leading edge and a top curve done using the TLAR (That Looks About Right) free hand curve or perhaps drawn around the designers shoe sole.
