Hi Gerrie
I hope that are you are well as well as family and planes.
My both YS works very well and the 3rd one (Backup - completly new) is resting, waiting his turn.

The motor which stopped on the last round stopped due to breakage of the outlet pipe of the muffler.
Celvin took pictures of the dead-stick landing and it is clearly shows that the pipe is missing.
I made a new pipe of aluminum and glued it to the muffler. Since it is going into the muffler in 45 degrees it has a
long guiding hole so it was not even necessary to mold it and 3M 190 epoxy was enough to glue it. The motor did not stop since.

The other motor which the crankshaft broke is also fine. I wrote a letter to YS Japan with the story of what happen.
4 days later the postman knocked my door and gave me a small package from Japan with a new crankshaft and apology letter.
This is unbelievable. Things can happen but such support is what makes the difference!!! thank you YS.
I opened the motors, changed the shaft. The motor is installed on my new Oxalys - also never stopped.

It was such an experience in SA NATS with the motors... Some time Murrfy works overtime....

Have a great day
Amram
