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.
