Fieseler Storch
Ed Holt (5707 Sierra Vista Dr., Riverbank CA 95367) built his
Fieseler Storch from BP Hobbies.
The Storch is powered by a Himax 2816 brushless motor spinning a
10 x 5 propeller. The model employs a Castle Creations 25-amp ESC.
“It fl ies great. The fl aps and moveable leading edge really slow it
down,” wrote Ed.
North Star
Kenneth Hollingshead (51 Bryant Dr., Albertville AL 35951; email:
[email protected]) built this model from a kit by Laddie Mikulasko.
The kit came with a note from Laddie stating he no longer owned the
rights to the drawings.
Kenneth wrote: “This kit left a lot to the creativity of the builder,
so I assembled it based on past kit- and scratch-building experiences.
The North Star is powered by a Super Tigre G-51 Ring with a threeblade,
7-inch pitch propeller that fi ts the available space. The radio is
an eight-channel Hitec with fi ve servos.
“I installed a miniservo in the power pod to avoid using a complex
routed 48-inch cable for the throttle. To ease servicing of the power
pod, I made the tail feather assembly bolt on. Also, the wingtips and
fl oats are bolted on,” Kenneth wrote.
Python
Dennis Carlsen (10193 Banner Lava Cap Rd., Nevada City CA
95959; email: [email protected]) based his model on the
Model 12 Pitts Python.
Dennis started with foam models to get the proportions right for
the fl ight performance he wanted, and then built 36- and 48-inch
wingspan balsa models from his own plans. He had a friend help with
CAD design and had the model laser cut.
The Python has a 60-inch wingspan and is legal for Giant Scale
events. Weight is 12 pounds and the model requires a 2500-watt
motor. Dennis uses a Neu 1515 1.5y motor, a 20 x 11 APC E propeller
and nine-cell battery packs for 2,700 watts.
There is little coupling on knife-edge. Loops, fl at spins, and
tumbles are all easily within the fl ight envelope. The Python has easy
takeoffs and landings.
If anyone is interested, Dennis can have short kits made.

Focke-Wulf Fw 190D-9
Darren Gibson (6801 Burnell Dr., Eau Claire WI 54703; email:
[email protected]) built his Fw 190D-9 from a Top Flite kit.
The model spans 63.5 inches and weighs 11 pounds. Power is
a Super Tigre 75 engine turning a 13 x 6 propeller. The covering is
MonoKote Flat Olive Drab and Flat Dove Gray. Darren’s model is
controlled by a Futaba FP-7UAP and Futaba servos.
Darren wrote: “When I land on the grass strip, I keep the
landing gear in the up position so it does not fl ip over on landings.
It does okay landing on its belly.”
Patriot
Gale Enstad (134116 Copper Crest Dr., Bakersfi eld CA 93306;
email: [email protected]) fl ew a friend’s Great Planes Patriot and
decided he wanted one.
During the build, Gale made some changes to the nose and
canopy for a more jetlike appearance. He also added anhedral to the
horizontal stabilizer. The tiger stripes turned out to be easy to make
utilizing a dressmaker’s cutting wheel.
A Hitec radio system guides it with an Aurora 9 transmitter.
Power comes from an O.S. .46. Robart retracts clean it up in fl ight.
Mosquito
Rob Askegaard submitted this model on behalf of his friend,
Bob Goff.
Bob (Huntington Beach, California; email: [email protected])
created this scratch-built de Havilland Mosquito from Cleveland
1/8-scale plans. The wingspan is 85 inches and it weighs
approximately 12 pounds. Power is provided by two Mega 22-20
motors with Mini Demon gear reduction.
The Mosquito uses Zinger three-blade wooden propellers and
Zinger spinners. Batteries are two Thunder Power three-cell,
6000 mAh LiPos. Covering is transparent UltraCote and paint. The
landing gear is Robart mechanical with Dave Brown wheels.

Quadcopter
Walt “Hank” Lehner (1225 Gardenia Ln., Prescott AZ 86305;
email: fl [email protected]) scratch-built this quadcopter
he calls Buttercup.
The aircraft’s arms are 11-inch segments of thin-wall PVC
irrigation pipe. Turnigy 2228/17 outrunner motors are mounted on
small plywood platforms screwed into the PVC arms. The motors
spin 8-inch Gaui quadcopter propellers.
At the heart of the quadcopter is a Hobby King V2.1 multirotor
control board that is preprogrammed for “plus” confi guration fl ight.
Power is supplied by a Value Hobby 2650 mAh, three-cell LiPo
battery.
