I can't wait for mine to arrive.

I calculate the extra lift generated by the heli foil shape and increased righting moment from reduced weight aloft is going to give me an extra 5 degrees of pointing ability....

Dont forget to include the increased speed your travler will enjoy (with your onedrop mclube) you will tack faster! NO ONE WILL EVER BEAT YOU!!!! EVER! (EVER)..

PS with all this brown-nosing... can i get a LayLine sponsorship? Say... free line and onedrop for life? smile

Mike, I am going to post the NOR to the Delta Pilot's web site, as there are quite a few in the Atlanta area, so maybe some will show up.

Or make them out of pre-preg carbon with a UV inhibitor already in the resin.


I know that the voices in my head aint real,
but they have some pretty good ideas.
There is no such thing as a quick fix and I've never had free lunch!

I think the bigger concern is the black carbon getting hot in the sun (VERY hot) and causing the resin to lose mechanical stiffness. The only way to help mitigate that is to cure the laminate at a high heat but that only makes it soften at a slightly higher temperature post cure.

There are resins that wont soften in the sun, but they need to be heat cured. Its easier just to paint critical parts white and use the room temp stuff.

Jake,
If you use a higher temp pre-preg and ramp up the cure to 110 - 120degC in the last few hours of the cure cycle I expect the softening would not occurr.
