Duncan,
In the Roncz3 preadsheet I got a value of 32.44 in yaw dampening. This value seams out of wack from the expected output. Since none of the experts want to address this on the forum I was wondering if this is just a glitch in formula. Could you look at my output and tell me what you think?

I always RTFM ! it's part of the gig

rtfm... Glad to make your aquaintance. I too am looking to put a BMW engine into a trike however. My interest is the Airborne frame with a K1200GT engine. It's water cooled, and I have all the electronics. How goes your search? ...do you have any contacts for a reduction drive? ...What are your thoughts so far?

So what's up with the Friends feature of the forum? One message to all?

Hmm good question, but I have no idea, one visitor message, and another dozens PM, that's how it works.
