I agree. I've put mine in pretty hard and the part that always breaks
is the hold down screw mount in the trailing edge of the fuze. I SAL
and it takes the forces. KISS is what counts in my book. I'd spend
my time on the Fuze. Next version is going to have a much longer (in
front of the wing) and different shape'd fuze. The one in the plans
works, just kinda ugly and requires nose weight to balance. Longer
nose... less weight needed 'cause I can move stuff forward.

I think you may find that a 1/8" c/f tube is too stiff to follow the
l/e contour as well. Even a wooden dowel needs to be carefully bent.

A 1/8" dowel is lighter than a similar size cf tube and the dowel is
plenty strong enough and bumb resistant and cheaper too. The 1/8"
diameter provides a good leading edge radius for the airfoil.

It's not a dumb idea and could be done easily. However, 1/8 dowel is
cheap, readily available, very light and very easy to work with. In my
opinion there wouldn't really be any advantage to using carbon for
leading edge.

Thanks John - I failed to look in the Misc Photo file - my goof.
Another question I didn't find an answer to while searching the
messages - has anyone used a carbon fiber leading edge on the bug to
save some weight over the dowel - or is this just a dumb idea (I'm
new to DLGs - so not sure if there is some technical feasibility
issue here as well). Thanks,

Jimmy,
Welcome.
Here's a photo from the bughlg group website showing the dimensions.

You can check out the other photo folders for how most builders are using carbon fiber to reinforce the tail pieces.

Just got the bug plan from RCM - I'd like to build it cross tail - What
are the basic demensions for the tail that are recommended? Do they
need any reinforcement?
Thanks,
