Not that I've heard of, but I believe it is in the works. Best bet would be to give James over at OMI a call and get it straight from the horses mouth.

YS91SR Viper Head

Really not needed on the SR. It is a very smooth running engine as is. Waste of money IMHO.

I also agree that it's not needed. It has excellent power, with great torque. It's also very smooth.

I would just keep it simple. BTW, I have used a Viper head on the YS91ST and the OS 91 SZ H. I now have the YS91SR in one machine and the OS 91 SZ H with Viper head in the other. I like the straight forward tuning of the YS91SR and the torque it has. The Viper head works very good on the OS engines to smooth them a bit and for better cooling. The SR really doesn't need this.

To hover is divine, the alternative is rather PLANE.

Thanks for the feedback, I wanted to through that question out there. I've had great luck with my YS50 and just purchased the YS91SR, so I excited to get that in my N700.

I wouldn't say not needed, until it's out and some test on it. You can never get a motor too smooth, or have too much power.
