The Mantis series of wings have evolved over time. It started out as a 120"
wing with a 7037 airfoil then an MH32 airfoil. More recently there was the
Aegea Mantis wing which used the AG series airfoils of Mark Drela with a
span of 130".

The Aegea wing aerodynamic design was something that mark Drela did as a
favor for the CRRC club Members who wanted a larger wing to put on their
Mantis fuselages. these guys also wanted a wing with Drela airfoils. The
only problem with a Mark Drela Design is that the structural design tends to
be very complex and too dificult to make on a production basis for sale. I
took the Mark Drela aero design for the Aegea wing and used my own very
simplified structural design to produce the "Aegea Mantis" wing. This wing
uses the aerodynamic design of the Aegea wing but with a simplified (for
production purposes) carbon tube and stressed skin structure. this Aegea
wing was quick enough to build that it could be produced for sale. It was
also somewhat heavier than the Drela design and not strong enough for F3J.
The methods used to produce this wing are shown in detail on my vac bagging
video which you are probably familiar with;

I could also dig up some links to posts where I have decribed the exact
structure and layup of the Aegea mantis wing.

Recently I have been working on a redesign of the Aegea wing structure which
will hopefully be lighter but will be able to take F3J launches. I am
currently building two of these models for our US F3J team selection
contest.

Mark Drew up the Aegea wing plan before he ever built a 3M wing for himself.
No 120" Aegea wings were ever built as far as I know. When mark did make
himself a 3m model he first refined the Aegea wing plan into what became the
Supra plan. The Supra wing is just an Aegea wing with a slightly higher
aspect ratio and with a bit more forward sweep to the wing. The forward
sweep was to prevent the wing from twisting so much on a hard launch.

Tom Kiesling's F3J models are taken from Mark Drela's Supra plans. Tom's
models use fuselages molded by Mike Lachowski which are not exactly to the
Supra plan but similar. Tom used a spar system and a skin layup which was
different from Mark's plan but was more efficient than my simplified tube
spar system. Tom used a real spar with carbon cap strips. The skin of his
wings is made from 2oz  (aprox 67gsm) carbon/aramid fabric and is only for
torsional stiffness, the wing spar carries all bending loads. Tom's
structural design is a compromise between Mark's very efficient design and
my simplified design. Tom has made three of these Supra models. The heaviest
is 64oz, the lighter ones are probably around 60oz or even a little less.
Tom's wing is stiffer than Mark's original Supra so it does not bend as much
on launch.

Let me know what information you might want to know about the mantis or
Aegea mantis wings. I don't think you will find them very interesting, they
are heavily compromised towards production. For information or details about
Tom Kiesling's Supra you should contact him. I am not familiar with the
details of his construction methods.

You already have Mark Drela's Supra plans I am sure. Tom Kiesling's methods
for building the Supra would probably interest you. Clearly Tom's models are
F3J capable and the build would be somewhat simpler than Mark's methods. Tom
has not published any plans or articles about his models. he is not one
spends a lot of time on line. I am sure he would not mind recieving an email
from you, I would think that he could at least give you a description of his
wing structural design.
