Pat,
I recently bought a MACS ''universal'' strap-on for my Webra Speed .61. It works well. The only problem is that the Webra exhaust opening is not milled smooth, so I get a little exhaust leakage around the fit. I'm going to try making a gasket from automotive (heavy) gasket material to see if that seals it up a little better.

My Deception is ready to fly again and I did cut a gasket for the joint between the Webra Speed .61 exhaust stack and the MACs Universal muffler adapter. I'll report how well that works after I get out to the flying field again.
