I was also charged 40 Euros plus shipping for the two main cylinders.

The gear simply do not cycle reliably with the small cylinders when you are in the air. I wanted a jet that actually works... My rep would not deal with it - he sent me direct to Erwin.

Erwin isgood to deal with but not free I had him make some gear for my Boomer XL at the same time. He was slow getting the stuff made and shipped but I eventually got it and it is very nice stuff.
