that's what I was thinking too, a rod through the aluminum material, hard to say how it would do in compression when it's pushing the aileron back up. might have to find a way to buy a length and take a better look at it when the wings are joined and mounted.
the hard points for the slave strut would have to be directly behind the I struts, it would be nice if the ailerons were there too, shouldn't be hard at all to move the servos out there, and put hard points in the ailerons there too.
anybody have some scraps of red Ultracote?? lol
