I bought 4 of the CH horns for elev and ail. I was going to use the dubro pull-pull setup that I bought for the rudder. Do you think I would be better off to use the ch horns I purchased for the ailerons on the rudder to save some tail weight? I have the 3" servo arm, but I would assume it has holes so I could use the 1" horns with my 3" arm on the pull pull.

Should I save the weight and use the ch horns on the rudder? and use regular dubro horns on the ailerons? I dont really want to spend another $17 on another pair of the ch horns.
