These pictures were taken during the first few flights of
Ver. 1.0 on September 12. It used a 10A draw geared Speed 300
motor. I'm now using a 3.5A Titanic Airlines Speed 280 and have
my hands on an out of production model that only draws 1.5A. I'm
currently looking to reproduce this kind of performance if at all
possible.
After the motor selection is finished the airframe will be
improved in several ways, and it might even sprout ailerons !?
The wingspan is 33 inches, with 210 squares total area.
I'm using a Tetra rx, two S-80 (9 gr) servos and a
Castle Creations 25 amp ESC. The motor is a geared generic Speed
300 type. Ready-to-fly weight without the battery is 8.1 oz.
The gearbox is my own design, with 2.5:1 gearing. The motor draws
9 amps using a no-name 7.25" prop. It's overpropped and I'm now
building a "thrust tower" like the one shown in the September S&E
Modeler to get actual figures so I can select a better motor /
prop combination.
I've flown it with 2 battery packs: 7 x 600AE Sanyo NiCds that
weighs 5.1 ozs, and 6 x 1200 NiMhs that weigh 5.9 ozs. I didn't
bring a stopwatch, and I don't know the duration with each pack,
but duration was fine and performance not much different with the
lower voltage / heavier pack. It glides along very nicely without
any power, and would probably thermal when using a smaller
battery pack like 6/7x350 NiCds.
The pilot for a few flights was a confirmed "slimer" jock, who
was surprised to find himself grinning foolishly at the end of
each flight.
Changes on the next model will include a removable v-tail,
strengthened landing gear and a slightly wider fuse that will be
able to accomodate either the current motor or a Speed 400 motor.
I'm hoping to build a few other variations around this wing: a
flying wing with tractor prop, elevons and fixed rudder, a
pusher canard, and maybe even an electric control-line.
