ok I am somewhat perplexed..I have a gp easy sport arf.. I am using a os.46fx and am not sure whether to mount it on the mountsupplied simply drilling holes and using self tap screws or drill entirely thru the mount and use nuts and bolts to secure it..I am not sure given the power of the engine if screwing the engine to the mount willeventually vibrate l;oose ..the bolted version seems safer ..opinions please..
