That looks great. Nice work.
I've done that but just found the 272 was easier to break free and then clean up the threads.I started using Permatex Ultra Copper on my muffler bolts. Never had one come loose since then.
I didn’t buy it new so I’m not worried about it. Club member has a brand new one he dropped off at the field for me to get it back in the air but they won’t stay long. I plan to upgrade all around to either KST 215mg or 315mg. Basically what these new 48” planes from EF can dish out the old hitec’s can’t hang anymore.I’d see if Hitec will repair it or replace it.
