When I set up my spoilers via strings on my Marauder I can only get about 25 degrees of deployment when fully open. The single spoiler servo is a Hitech HS-85 with a full size arm on it, and there is (was) no binding of the arrangement.
I got so frustrated with trying to figure out why they weren't deploying that in my haste to get the plane flying again after a crash I just covered over the spoilers. Now that winter is here I have some time to fix these things.
Something tells me that I must have the geometry incorrect *or* I am not getting enough throw from the servo. But with a full size arm (fixed to slightly forward of perpendicular to the servo strings when closed) and the strings mounted to the outermost hold I think I cannot possibly get less leverage and more distance pulled at the servo end. The holes in the spoiler horns were pre-cut in the kit and are at the end of the horn.
Has anyone had to troubleshoot spoilers that did not open sufficiently before? If so, what did you do to get them to open at 45 or more degrees? As I had them set up the spoilers on my plane were marginally efficient.
