hello all i am putting the radio gear in a super sportster 40 mrk II i run into a little problem the instructions show using a servo with the 4 holes in the arm i cut all the excess arms off but the one,it is done for the rudder and elevator, and throttle. when installing the throttle servo it will hit when put in the outer hole, so i moved it in to the third hole for the elevator seems to be fine, also the throttle calls for a 4 hole arm but will hit the side of the fuse, so i plan on putting a servo arm on with three holes. will this have a bad effect on the controls and is their any suggestions that could be done never had this problem before. also do the instructions just use the basic four hole servo arm for reference thanks mike
