Er, I guess the subject pretty much says it all. Thanks to anyone that
can help me out here.

Yes, Estes BT-80 size and Aerotech 2.6" cones are interchangeable.

Hmmmmm...
I was thinking of getting a Estes Pheonix-style nose cone for
my B-sword but now that you've sent this, I have to ask
if there is any difference between the Estes Pheonix-style
nose cone and the AT long ogive 2.6" cone  (ie: is it longer
than Estes').

They are interchangable to a point - they all fit in tubes with the same I.D.

However, the Aerotech and LOC tubes have a little bigger shoulder due to thicker tubing than Estes. So, Estes cones
leave a lip at the shoulder on LOC/Aerotech tubes and LOC/Aerotech cones are a little 'fat' for Estes tubes.

PML cones are less interchangable, as the PML tubing is thicker than LOC/Aerotech. You can interchange LOC/Aerotech with
PML, with much the same results as interchanging Estes with LOC/Aerotech. I would not use a PML cone in an Estes BT-80
or Estes cone in PML tubing ever, though, as the gaps are differences are too noticable.

Yes indeed, they do fit even though youd have the wider BT edges protruding
some.  Ive used these on my HPR gliders well, and they do hold up to Is at
least.  And thats with NO reinforcements...

One more thing:  They are thin and will Not survive a crash (dont ask how I
proved this) whereas a 'standard HPR nose' will make it.

Yes, the AT ogive is at least a couple inches longer than the Phoenix
cone -- it's got a distinctly slender look to it, where I've always
thought the Phoenix cone was on the stubby side.  To get a look at it,
check out a Binder Designs Spike (there's a picture in Magnum's online
catalog, among other places).  This cone is even (apparently) designed
for thinwall tubing, as it leaves a little step with the heavy tube
supplied in the Spike kit; it should be very nice on a Broadsword (or an
Optima, for that matter -- and I've got a spare lying around...).  B)

The shoulder diameters of both match. The LOC tube is thicker, so an SBB
nose on LOC tubing will have a small step at it's base. My Super Ranger is
built this way. From anything over a couple feet away, you'd never notice.
If it really bothers you, bevel the tube a bit to make it less noticable.

The LOC nose cones are also made of thicker plastic than the Estes and
are heavier, and so for some models will need less nose weight.
