hello, i purchased a used ms60, preivous owner dropped heli and broke couple of parts, it does have a ys91ac(4-stroke), which has a broke part of the cyclinder head where the air chamber meet,(115.00 repl.) it has all the clutch, fan, motor mount and so on for 91ac, so i was wondering if i was to switch over to another
heli engine besides the same one, which ones could i use, but use the same accesories for the ya91ac. thanks...
