Hey Kess can you post those W&B charts. I'm sure alot of us would like to double check our numbers.

Creare invented these spiral screws a few years ago, we could use them too (even the Dreamliner does)

(off topic) Mark, thou simply must fly over to UCMerced once, Professor Roland Winston's solar "non tracking" wide angle compound parabolic concentrator is awesome, no suntracker, motor or battery required

As Mark suggested, contact him, he can help. The JT2 information is also
in the manual. Let me know if you don't have Mark's phone #. Calling him
on his cell is the best way to contact him.

Let me know how this works, glad to help you if I can.

You know, after this discussion, we should put up the w&b information on a folder on the Earthstar site, that way is available to all at a click. I did notice that the stock moment arms for the J and JT2 are the same, but the Gull 2000 and Odyssey are different.

My old Odyssey would keep it's nose wheel on the ground with about 8 lb
of pressure.

On a lark one day. I put the plane on a rigid piece of platform and
rolled the whole thing back and forth on top of a pipe as an axle.

It was great fun. And, my friends and I, repeated the experiment with
people and fuel on board.

It's not something you could transfer to a set of moment arm equations
though :-(

And ideally, the balance point on the pipe would transfer right up the the proper cg point on the wing, and not change much with full fuel and people. Wow! What a novel idea, a super fast way to check cg’s!!

[rahulchoudhary73]

what's the pipe dia? almost winced imagining something scratching the gull's bottom, even if rolling contact.

wonder if we'd ever calculate the Ra, Rz of the Gull's surface roughness one day. they're in micrometers as the arithmetic mean and ten point mean of a chosen surface length; yet to figure what kind of a tool would calculate all that in a simple way
