1956 Ramrod 600
Fritz Jetten (email: email@example.com) submitted the information and
photo for Azalea City Model Aeronautics club member Frank Madison
(Mobile, Alabama; email: firstname.lastname@example.org). Frank refurbished a gas-powered Free Flight model, the 1956 Ramrod 600, which was originally
built by George Delius in the 1950s. It was the Nats champion in 1956
in California, and the 1957 Willow Grove Nats champion in Pensacola,
Florida. The plans were by Berkeley Models, Inc.
The old wing construction is seen through the clear covering,
and the fuselage and tail feathers are silk covered. It has a 63-inch
wingspan and the fuselage is 37 inches long. Powered by a Forster
Brothers . 35 gasoline engine with a 1940s ignition system, it runs on a
3: 1 gasoline and castor oil mixture. Battery power is 3 volts. A negative
timer cuts off the engine at a preset time of up to 30 seconds.
The tail is outfitted with a dethermalizer controlled by a fuse—one
minute and up. After the fuse burns out, the horizontal stabilizer kicks
up, making the airplane come down.
Frank had help rebuilding it from fellow club members Wayne
Boudreaux, Henry Waltman, and Joe Krebs.
Steve Betts ( email@example.com) built this Neutrino in 2014
from December 1967 American Modeler plans, number 1267, that
were designed by Dave Youngblood.
The Neutrino has a straight, 15%-thick symmetrical airfoil at the
root that increases to 18% thick at the tips. There is no washout and
only a slight 1/16-inch elevon at neutral. Steve used Family Dollar $1
foam board for the ribs, with the cardboard peeled off of the outward
side to allow a taper to be sanded into the ribs. The rest of the
construction is balsa.
Steve’s Neutrino is powered with a Bigfoot 32 770 Kv brushless
motor with a 13 x 10 propeller. It uses a four-cell 3,300 mAh
LiPo battery and a 70-amp DLUX ESC. The power system pulls
approximately 1, 100 watts. The aircraft also features HobbyKing metal
electric tricycle retracts. The Neutrino weighs 4 pounds ready to fly
and Steve uses a Hitec Aurora 9 radio system for control.
The Neutrino flies like a typical Pattern airplane from the late 1960s
and will do all of the period maneuvers except spins and snap rolls.
Steve wrote, “I was pleasantly surprised to find that this airplane
is an everyday flier. I was familiar with the Neutrino because my
father built one back in 1968. His had an all-foam wing with tag-board
Peter Donk (Wayland, New York; email: firstname.lastname@example.org) built
a Double Decathlon from two Seagull Models Decathlon ARFs. The
Double Decathlon features an 81-inch wingspan and weighs 12
pounds. It uses twin O.S. 55AX engines and a Futaba 6EX 2.4GHz radio.
The wing sections were cut where the factory sheeting ended and
rejoined. The aluminum wing tube was lengthened and connected
with a hardwood dowel rod. The horizontal stabilizer was cut at the
center point and lengthened appropriately. Custom main gear and an
aluminum fuselage brace with a carbon-fiber wiring conduit rounded
out the necessary modifications. “The airplane flies fast and well with
no bad tendencies whatsoever,” Peter wrote.
The photo was taken shortly after its maiden flight on June 7, 2015, at
the Genesee Valley Aero Modelers flying field in Canadice, New York.

“I remember doing the same with my father.”
