When I saw the lap speed of the top qualifier I had to check out the airplane. It seems that the David Hoover designed AR-6 named "Endeavor" was designed by a fellow with no Aeronautical, or in fact, no engineering experience at all.
The Aircraft is sleek looking for sure, but likely wouldn't produce a very good profile model for 1/8" scale racing, due to the very small fuselage area ahead of the stab being it's weakest point. Wing mounted LG arrangements have never been very successful in 1/8" Scale Racing either.
Still, very nice looking airplane.
