The covering is solartex throughout giving a strong skin;
this material is great for covering tight curves. She replied describing her maiden flight--- ‘It levitates’ she
said, just like the model I thought. It must be the thick wing
The maiden flight was on the 13th Feb 2011 at the then section. Kate kept the plane for about 8 months and then
Papakura, Manukau club grounds at Clevedone near sold it to the Real Aircraft Company at Breighton
Auckland. Aerodrome where it resides.
Opening the throttle gently, she trundled along and soon
the tail came up and she then seemed to just gently raise
–a sort of levitation with slow forward motion. At about 70
feet she gently dropped the port wing , I gave a correction,
then she dropped the starboard wing and this continued
from side to side until I pushed a great deal of down
elevator increasing speed but now she was about 30 feet
from the ground. After my hands had stopped shaking, a
gentle turn to the right, gaining a little more height and
dialling in ALL the down trim, she still would not fly level
flight without lots of down elevator, but at least the
swinging from side to side had stopped. I assumed this
was gentle stalling, but unnerving on the maiden flight.
I brought her round and landed gently with down stick,
flaring at the last minute. Obviously I had got the angle of
the stabiliser wrong. Back at the shed, I packed 3 mm of
hardwood under the leading edge, tightened the locking
nylon stabiliser screw and waited for another suitable day.
Subsequent flights confirmed the new angle about ok, but
still needed a little down trim. The take-offs and flights
were still marginal and the home-made Par Lundquest
design sprung undercarriage was taking a hammering. I
decided to fit a laser 100 engine with a 15 X 8 prop and a
pair of Oleos from Unitracs UK as per the photo above.
This needed a complete modification to the engine
mounting, some lead in the radiator removed, new Litho
cowl parts and we were ready for further tests. My model
now had a total weight of 5.7kg, a little more than the
designed calculations and about a kilo heavier than Par’s
prototype.
Subsequent flights have proved a joy. Adequate power for
take-offs using throttle control for scale flying once
