I designed the shockwave because I wanted a model that was fast, but
could still perform RC-1-like aerobatics. I chose a very thin symetrical airfoil
that keeps the airflow laminar longer than a "normal" symetrical
airfoil, because the thickest point is at 40% chord in stead of the usual 30%.
Since the airfoil was so thin, I had to installed flaps to make sure the
landing-speed was subsonic...
This model was also powered by my trusty OS-max 32 F-ABC, which with a 9x6
APC propeller enabled me to make vertical starts by just applying full power
while holding the nose straight up and letting go. It would then very sowly
climb, torque-rolling all the way.
This will go even better if a .40 is installed on the plane with a 10x6 or 10x7
propeller.

Just as the Galaktos, the Shockwave did exactly that what I
designed it for, It is to date the fastest plane at our field.
During a speed test the plane flew horizontally an average (taking from the up-
and downwind speed) of 221 km/h.
