...Guess I need to get me some JB Weld Tuesday in my gallivanting around on my day off!
I have never messed with JB Weld before..How long does it take to cure? And if during that cure time while it is still pliable I could insert a motor casing to ensure the ring is centered?(Of course making sure there isn't any of it IN the motor tube first!)
Putting my HAMR on the MR-1 was my first experience with JB Weld as well. IIRC it takes about an hour for it to set up, and isn't cured completely for 12 hours - it's been a while, so i'm probably a bit foggy on the exact times. Yep, after I got it set in, I slid a used 38mm motor and casing into the mount, just to check, and it lined up just right.
But, I only got to fly it twice - on the second flight, the MR-1 apparently landed on a taxiway butt end first, at the airport where Tripoli Houston flies, and knocked it a little out of round. Had to take pliers to it to get it off and won't thread correctly - gonna send it back home to see if they'll sell me whichever of the parts is out of round, separately.
For my money, it's a nice system, but if you fly it only twice, it can be expensive.
