OK, does anyone know where I can send the head of my Magnum 91 FS to have a heli-coil installed? Thanks, Guy

Look in the classified section of any modeling magazine for the address. Clarance Lee does an excellent job on heli-coils.

A local machine shop might be able to help. ENJOY !!! RED

back of MA has Clarence Lee's ad

I can't offer any advice on helicoils, but I've just flown my first Magnum, a .91 four stroke, and it is a great engine.

There are a few guys that do not care for magnum engines, they do take time to break in right but they are a beautiful running engine once broken in, just take the time it requires, then you will have one of the nicest engines out there, i have talked to many guys with magnum engines and they all seemed to take a bit longer to break in but once they have some time on them, you will be very happy with the engine specially the way they idle, so slow and even, and have nice power.
