What do you mean by successfully?
Were the models overweight?
Were the times aloft pretty good by comparison?
What can be done to improve them?
Is that type of carbon prepreg available only in Europe? Any info on this
subject will be greatly appreciated. Ciao, Phedon.

Carbon tubes were successfully used at the 2012 world champs. I suspect
we will see some this year as well.

According to Steve Brown a very stiff tube is worthless because it just
does not flex downwards enough in order to give some very much needed
down thrust during the initial burst.
So carbon is out on all counts!

The weight of 225 mg is for a carbon tube with a length of 10". 9" I can
also make at 200 mg.
My ID is 4.8mm = 0.2". They are probably stiff/strong enough to use
without bracing.
OK keep your process secret, but please share the material you used ;-)

Carbon is unsuitable for motor tubes.
My tubes have no carbon. Prepreg is too heavy.
My process will remain a secret.
What length are your tubes as you use them for official flights?
I shall be sending Mike Kirda a 9" one in order to test it
Mine are 1/4" I.D.
