Dave,

What with the rpm specs be on the new .91 close to the .80? I'm wondering about gearing.

Thanks

Rick

The 91 will use anything from 7.9 to 8.5 to 1. Same as the 80. If you are doing 3D, use 8.5 to 1.
If it weren't for the west coast dock strike, we would have these by now.
Sorry for the delay, we appreciate your patience.

Good Flying,
Dave
