How can I fix this?
Hi guys,

Does any of you know if the muffler will still hold with this broken mount or how to fix it, JB epoxy or another method?

Tks Pilotheli

Maybe a welding shop can fix it.

I've seen great results with Technoweld , my father uses is quite often . Basically you should be able to build up the damaged section and then file it level and tap out a thread .

In the magazine Model Helicopter World, I'm sure one of the contributors, John Bottomley, had a similar problem and built up the area with JB Weld.

Other option is a new crank case or motor!

If you know someone with a mig welder they should be able to rebuild the area then carefully drill out a new bolt hole.http://www.webstarts.com/micksscalehelicopters

Cheapest way is to get a piece of aluminum slightly longer than the distance between the two bolt holes. Drill holes in it at the same spacing as the original holes. Put it on the non-exhaust side of the motor and use longer bolts straight through to the muffler. Basically it looks like a clamp on the cylinder but it works and is cheap.

Find (or make) a 3mm "U" shaped muffler clamp and just bolt your muffler back on.

Or maybe just a metal strap of proper length to go around the cylinder with a 3mm hole at each end to go under the heads of the regular muffler bolts.

Never tried it myself but have heard it works well. If you try it, let me know how it works.
