Yea i have a saito 56 and i plan on trading it for a 72 tomorrow. On the current GP motor mount the holes are drilled for .46 sized engines. I had to grind the holes for the front landing gear off of the mount since the carb on the 56 is blocked by it. Are there any other adjustable mounts without the ladning gear holes? Id prefer adjustable because drilling more holes is not really and option.
