On Saturday, August 14th, N821DT flew the first time. Serial # is 81905. Construction
time was 18 months from standard kit. Total man-hours 1300 which includes
paint. Engine is Mattituck IO-360-M1B 180 hp, Hartzell constant speed.
Empty weight is 1,134#. Engine instruments are Van's steam gauges, full vacuum
system, Skyforce IIIC moving map GPS. Paint is Sherwin-Williams Acry-Glo.
The airworthiness inspection went well. It was done by Jim Paine of Hendersonville,
NC. Jim is one of the new volunteer DAR's, and is first class. He has
a Thorp T-18, and understands what we're doing and why we do it better than any
commercial DAR. It was a pleasure working with him.
First flight was from a 2500' grass strip, lots of trees around here, so the plan
was to climb at a good angle (85-90 mph indicated) with right turn after takeoff
that would put me over the first alternate ditch point, an open field.
By looking at the pictures afterwards, the climb angle was about 70 degrees, and
I was still indicating 110 mph!!! Leveled off at 4,000', reduced power to
24 squared, and airspeed rose to 208 mph!! I thought "WOW....we built a FAST
airplane!!!!. After flying around for about 30 minutes, I stalled it clean and
indicated 100 mph. That explains the steep climb angle at 110 mph and fast
cruise. I stalled with full flaps and indicated 62. I talked with Van's about
the airspeed indicator, and they are sending another one to replace it. Static
system is Van's pop rivet type. They say that higher indicated airspeeds
are usually due to errors in the indicator itself, not the static system.
