Welcome to our website: We are located in Orange, California U.S.A.
We spend a lot of time on the computer with CAD and yes,
we still use the drawing board at times. We create special
aircraft designs with many  associated custom products, all
from scratch. If you have come to view several new Flying
Flea aircraft conceptual configurations and are interested in
the optimal
F5Family of airfoils that were especially
designed to enhance the Flying Flea performance and
safety  ........
You have come to the right place.

Chris's comments: The photos are of the HM290 built by Jack Johnson of Edmonton.  It had a 1500 cc
VW engine. It would cruise at 90 mph.  It had a minimum speed of 18 mph at high power and very high
angle of attack.   He flew it for many hours when one day it was burned in a grass field fire. Jack said it
was easy to get into a Dutch Roll condition - very scary!   I propose bungees to increase sideways stick
pressure.  Someone should test this out.  I have the sketches for whoever would like to try it.

Roy de Stadler's high quality built HM 293 Flea.
Look closely at the craftmanship. No glue spills
or runs visable.

Three months of engineering calculations and
other paperwork has allowed the Government of
South Africa to grant Roy the privalage of
having
the first fully registered HM293 home
built in South Africa. Registration Number ZU -
FGX.
Congradulations Roy. That was a lot of
hard  work. Without calculations to prove
adequate strength and safety, a homebuilt in
South Africa usually does not get to fly.
