New product news!
The YS 91 Long Stroke has been released and seems to be doing very well. I have worked very closely with Hatori mufflers in Japan to come up with the SB-19
muffler for this new engine.
This appears to be a very smooth running engine, and the power delivery and fuel economy is excellent.
The Viper head by OMI on the YS .91 short stroke makes the engine very smooth, adds more power, and provides better cooling. I have also asked OMI to do a Viper head for the YS 90 long stroke.

I have been working with SAB in Italy to come up with new versions of a 710 3D blade. We have two new versions of a wide chord 710 blade. The SAB part numbers are ART 0224 and ART 0225. These blades perform very well for all different flying styles.
I will be getting some samples of the new Duralite power box. This is an inflight battery system that has redundancy built in to it. We will report back after we see some samples. For more information please visit www.duralitebatteries.com.
A friend of mine has come up with an on-board glow igniter. I have been using these for the last 6 months and they are working Excellent! For more information go to
