Gary, I've been debating what to do about my eyebrow. For now I covered it
with some vinal as a temporary fix. I know Fletchair sells them (the
original). Is there a way I could see your eyebrow before I make the
desicion to purchase? Have you sold one to a Grummanite in the Mid-Atlantic
area? Maybe I could eye one over.

Hi Ned, yes I did get your message. To be honest, I forgot all about the
call. I am making the STC for either material so that I can make either.
Right now, they are going to be made out of fiberglass. Carbon would add
about
$1000 to the material cost.
if you want a cowling (or two) send in some deposits. Once the STC is
approved, I need to raise the cost to recover my costs over about a five
year
period. I figure that most of the planes getting the cowling will have
them
within 5 years. I sold 300 eyebrows in the first 2 years. I average
about 4 a
year now. I'm still amazed at how many people have never heard of them or
seen one.
If you want a carbon fiber cowling, I can make one for you.
Gary

How much weight savings might there be by going carbon? 10-20lbs might be
worth it, although with a lightweight starter too the CG might end up
farther aft than desireable. I'd be interested in the numbers before you
lay up my cowl.

Right now, the cowling weighs in at 24 lbs before paint and cam-loks. The
stock cowling weighed about 32 lbs. I just talked to Dave (Composite Dave),
he'll get back to me on how much weight we can save. He also told me the
cowling takes about 20-25 yds of material.
Dave is working on the Predator in Mississippi. It's all carbon fiber.
