Hi Pete.

Thanks for the update. I have been flying the Excelleron now for past several days with the new OS 1.20 AX and it has been a dream. The engine has all the power I need and then some.

One minor incident today, though. It was crazy. I was going through the Sportsman seqence, about half way though when all of a sudden the engine sound about doubled as though the muffler came off. Well, I immediately landed and saw that I had half of a muffler attached. It came apart at the center where the two halves join. The center bolt was missing. I thought it just came loose but I had checked all that stuff before flying so I was not sure what happened.

We said, "Well, lets go look for the other half, chances are about 1% of finding it in the area we fly in. Well,we walked over to the area over which I had been flying and sitting there, on the sand, was the other half of my muffler. The center bolt had broken. Not sure why. So, I had the two halves of my muffler but no bolt.

I will head over to the local hardware store and pick up a piece of either 8-32 or 10-32 all thread rod and replace it.

Other than that, this is a great combination..excelleron 90 and the OS 1.20 AZ.
