Generally speaking you'd want it as long as possible so as to use as little weight as possible. In our case the limiting factor is the arm/weight hitting the rear spar in it's travel. With that in mind I built mine to come withing 1/4 inch or so (weight and arm) of the spar. I'd have to measure it to know how long mine is but every airplane could be different depending on the aileron cutout, hinging, etc. Speaking of aileron weight arms, if it's not to late in you building process, you may want to make them out of steel instead of alum. The alum arms have been known to crack/break/fall off. I may have a friend of mine that does alum welding reinforce mine with some gussets. Hopefully someone will have the answer on the latch thing. My plans set is out in the truck. Larry Flesner
