DAG-1 Autogyro
Direct Control (DC head) sport model
This is a full size plan sheet.
Fuselage style: Built up
Motor: Electric or Glow (.25-.40 two
stroke or .26-.40 four stroke)
Rotorblade: #20024RB
The
DAG-1 is a fine autogyro model that looks great and flies very well.
It features a DC head (Direct Control) and can be set up with either
glow or electric power. Full size drawings and a CD packed full of
detailed building instructions, illustrations and pictures are included.
Our RotorBlade
Airfoil item #20024RB is recommended for this model.
The flight characteristics of this gyro are very smooth and docile.
You can use rudder for turns and add a touch of aileron for roll.
(You only need a touch.) It will fly with rudder alone if you like.
The combined control inputs of aileron and rudder allows you to make
a very tight turn. Direct pitch in the head coupled together with
elevator will give you the best control if using a slow servo on
the rotor head. However, the actual elevator hinged control surface
is not needed if you can install a very fast, high torque standard
size servo for pitch and roll. Pull the rotor head back as you take
off down the runway to pre-rotate the rotors. Once the rotors are
up to speed, drop back to the neutral position and wait for the gyro
to lift off the ground. It is amazing to watch.
Here's a suggestion if you are going with direct pitch and roll
with the rotor head: Choose a servo that's suited for the job. In
this case it is recommended to use standard size heli type /FAST
and high torque servos with a minimum 56 oz of torque and maximum
rotation speed of .20 sec. As an example, you should use standard
size high torque servos with 110 oz. and .13 rotation speed in the
head of this gyro. The spinning rotors being pulled thru the air
produce a lot of drag, and therefore a heavy load on the servos.
So going with the high torque/fast helicopter type servo for the
direct pitch and roll will keep the head in check and offer you the
best chance for continued control authority and successful flights.
The elevator (if used) and rudder use mini servos – not much stress
on them so there is no need for a standard size servo. The mini servos
in the tail keep it light, too. We recommend an HS 85BB for the rudder
and an HS81 for the elevator, if you are going that route.
Power needed:
Electric - anything that will produce minimum of 4 lbs of thrust.
Use an AXI 2820-12 to a 2826-12 motor and 4200 mAH, 11.1 volts
lipos.
Glow - .25-.40 two stroke .26 to .40 four stroke
The rotor plate is made of G-10 Garolite fiberglass, which is strong
but flexible. You need flex to allow the blades to flap. If it were
too stiff, the gyro would veer to one side or the other.

"SIMPLE-G" Autogyro
Direct Control (DC head) sport model,
designed by Jim Baxter
This is a full size plan sheet.
Fuselage style: Profile
Motor: Graupner Speed 480 geared 3.45:1
motor or equivalent
Rotorblade: #11218RB
This
new model will accommodate glow engines ranging from .09 to .12 in
size, and has options for different flex hinge rotor hubs.
The Simple-G is small, light (19 ounces), hand launched, and is
direct servo controlled (no rudder or elevator). The one pictured
here sports three sub-micro servos, a Thunder Tigre .10 engine, turning
a 7 x 4 prop. With a 32" disk rotating on two small model car
bearings, it has a great 3.4 low disk loading. The model can be easily
adapted, during the building process, to be powered by most engines
in this range.
This is an easy to build and fly model and does not require machining
of any parts, and can be dismantled sufficiently to pack for travel.
Designed by Jim Baxter.

NOTE: As of September, 2002 the plan has a functional
rudder installed.

SPARKY Electric Autogyro
Direct Control (DC head) sport model,
designed by Jim Baxter
This is a full size plan sheet.
Fuselage style: Profile
Motor: Graupner Speed 480 geared 3.45:1 motor
or equivalent
Rotorblade: #11218RB
A
Direct Rotor (DC) controlled electric autogyro evolving from the
original Simple-G (glow model) and flight tests of smaller Sparky
1 and 2. This model will accommodate several different electric power
systems. Originally designed and flown with the strong Astro 020-802g,
it has been successfully test flown with the Graupner Speed geared
480, an outstanding German Lehner motor, and I'm sure it would accommodate/fly
with the strong Hacker motors and a few of the new outrunner motors.
The plan shows the option for the first two, and with a little adjustment
it could be adapted to the others.
The Sparky Electric is another small, light (20-21 ounces), hand
launched, direct servo controlled (no rudder or elevator) model patterned
after the Simple-G glow powered model. It use two sub-micro/micro
servos, and it is recommended you use one of the latest three cell
(11 volts) "high discharge" or "Super high discharge" Poly
Lithium battery packs of at least 1500 to 2000 milliamps for maximum
performance. Originally it was designed for an 8 cell 500AR NiCad
battery pack (or stronger), spinning an 11 x 7, or a 12x6 propeller.
With a 32" disk rotating on two small model car bearings, it
has a great 3.75 oz/sq. ft. low disk loading. Some modelers have
mechanically connected the roll servo to a small rudder, which will
increase the control capability similar to the latest version of
the Simple-G glow powered model.
It features 1/8" light plywood, 1/32" Polypropylene for
the flapping hinge, model car bearings, and a few screws or bolts.
The control head also uses a central hinge of 1/32” thick polypropylene,
and is also made of simple light ply parts.
This is an easy to build and fly model and does not require machining
of any parts, and can be dismantled sufficiently to pack for travel.

You can view the actual instructions and download/print a copy of
the Sparky instructions by simply clicking
here. This file is large
so it may take some time to print out, depending on your system.
Instructions are no longer furnished with the plan; you must print
them out following the link above.

TWIST model autogyro
Direct control (DC head) sport model,
designed in 1998/1999 by
Jim Baxter
This is a full size plan sheet.
Fuselage style: Built
up
Engine: .061 - .10 glow
Rotorblade: #11218RB

sUITCASE MINNIE Autogyro
A direct control (DC head) sport model,
designed
by Jim Baxter
This is a full size plan sheet.
Fuselage style: Profile
Engine: .15 glow
Rotorblade: #11218RB
Plans are available for this small, .15 powered, one of the original
totally direct rotor controlled hand launched models. One of the
useful features of this model is that it can be completely disassembled
and packed in a suitcase for travel. It has a 33 1/2" rotor
diameter, weighs 30 ounces, and uses 3 sub-micro servos. No machining
of any parts is necessary. For more detailed model information, please
click on the photo.
Instructions are available for printing by clicking
here.
The SUITCASE MINNIE is an upgraded version of the successful "MINNIE." It
was designed, built, and flown by Jim Baxter. The new model incorporates
a slightly re-designed fuselage body, and a four-bladed rotor hub
utilizing a polypropylene disk for hinging. The photo in the center
shows this model completely disassembled for ease of packing into
a standard suitcase for transport.
Virtually identical to the original MINNIE, this version has a rotor
diameter of 33 1/2" and weighs 30 ounces, and is powered by
a Thunder Tiger .15 engine turning a Master Airscrew 8 x 4 prop.
This model features a fully tilting rotor controlled directly by
two micro servos.

CIERVA C30A
AUTOGIRO C30A COMMANDO DIRECTO
Cierva C.30A direct control (DC head) sport scale model,
designed
by Emilio Cabezas, Madrid, Spain
This is a full size plan sheet.
Fuselage style: Profile
Engine: .15 - .25 glow (.20 recommended)
Rotorblade: #20024RB
These are excellent plans designed by GyroNut Emilio Cabezas, and
drawn by Paco Sanchez. An experienced modeler should be able to build
from the plans. While no instructions are available, the plans are
complete and easy to follow. This is an excellent flying autogyro
featuring a single TEETER BAR two-blade rotor, and employs both pitch & bank
rotor tilting, with rudder assist, ROG or hand launchable.
Two plan sheets, featuring a 40" rotor, profile fuselage, powered
by a .20 engine. Emilio reports that this model, when built light,
has been flown with the power of just a .15. One slightly heavier
version is currently flying with a .25 engine. When building this
model, consider making allowance for an engine up-grade if found
necessary due to (1) your building ability (2) the altitude of
your flying field. Some excellent photos of this model are coming
soon.
This plan is now only available with English translated labeling.
