Exhaust temp vs solder
I learned today that the exhaust temp of my Enya 50SS is hotter than the melting temperature of solder. I had soldered a muffler adapter onto a Soundmaster muffler to make it fit the Enya hole pattern. It worked great for several flights until I did a prolonged run at full throttle. Then the muffler came unsoldered from the adapter in mid flight and hung on by the pressure line. It was actually pretty entertaining to watch.
Can anyone recommend a better way to attach the muffler to the adapter plate? How about JB Weld? Silver solder or braze?
Thanks!
