Bumble Bee in English, using three-views and photographs from the
This model spans 83 inches and weighs 15 pounds dry. Its cockpit
is located at the level of the wing’s LE and above the nose. The
unusually high landing gear ensures a safe landing on rough terrain.
The wing is a gull wing with three parts. The outer wing has
15-inch LE slats (not pictured) at the end of each tip for support. This
single-seat, single-engine monoplane is mixed construction of balsa,
fiberglass, and pine spars with stainless-steel rod landing gear.
“The Ĉmelák is an ideal aircraft even if it’s not a thing of beauty.
But it leaves a lasting memory to all who see it,” wrote Robert.
Michael Meskin (255 Coyote Trail, Rifle CO 81650; mikemeskin@
hotmail.com) built this stick-and-film Old-Timer model from a kit by
Spirit of Yesteryear.
He used an O.S. . 10 electric motor with a Castle Creations
Thunderbird 54-amp ESC and an 11 x 6 propeller. On its maiden flight in
his back pasture, in less than one minute of power at half throttle, the
Playboy was riding the thermals with resident hawks.
“The kit was mildly challenging, but a lot of fun and well worth it,”
David Weiss (9573 Fresh Crown Ct., Las Vegas NV 89148)
converted his latest project to an EDF.
The Boomerang Nano’s fan-and-motor combo is a Sapac America
100mm fan with a Scorpion 4035 motor and Castle Creations HV
120 ESC. David used Tam Jets brakes, wheels, and custom intake.
A Spektrum DX8 controls the aircraft. Other features include t win
six-cell 5,300 mAh batteries in series, and Robart retracts and struts.
After the picture was taken, David replaced the retracts with E-flite
and Tam Jets trailing link struts.
“This is a great flier and the best thing is that it did not require an
AMA turbine waiver. Many thanks to Tam of Tam Jets for all of his
assistance on this project,” wrote David.
John O. Suess (1217 Loblolly Ln., Conway SC 29526; email:
email@example.com) built this Grumman Goose from AMA plans with
his own interpretation.
The Goose is stick-built with better balsa and the stringers are
spruce. The wing frame has 1/16 caps to add more strength. The body
is sheeted 3/32 balsa and covered with Solartex.
John’s model uses Futaba sport servos and a Futaba 2. 4 GHz
receiver. The motors are E-flite Power 10 brushless outrunners with
30-amp brushless speed controllers. The Grumman Goose weighs 4. 5
