What are u flying on ur magic??
Well Now! I'm in the same quandry. I think I'll have to change the Motor to a YS 53 as this Magic only ways 3 lbs 10 Oz with a YS 63 on it. The 63 is going to be way to much! hmmmmm No Prob same Motor mount. Swap time.
Bob If your's weighs 3.10 with a Leo then you must be using full size servo's as I have HS225MG's and 1 HS 81MG for Throttle and mine is the same weight.
