300DF is a light motor, designed to fly park flyers. Use the 300DF with a 3:1 or
gearbox and large prop 8x4, or a speed demon on a 5x3 inch or smaller prop.
Lipo or 3 cell Lipo can be used with all this motor, but best performance can be
achieved by using 3 cells+4.5:1 gear ratio with 12X6, or 11X7 or 11X4.7 props.
The data for other props and gears:
For 3.4:1 gearing
use 11x7 HD, 11x4.7 SF
For 4.5:1 gearing
use 12x6, 11X4.7, 11X7 SF
pusher props have proven to be spectacular. It has been flown with Wing Warrior
Zaggis, Wattage HyperWing and Edge RC delta wing planes. Using a small prop
direct drive and wings around 16 Oz weight, this is the best you can get at this
price. With a 5x4 prop it draws about 12 amps. It is equally good with large
props in a gearbox. So decide whether you want speed - 50+ MPH or slow fly with
large props and a lot of torque and use this motor for both.
Max Current: 10 Amps.
Weight: 29.7 grams
Shaft Diameter: 2.3mm
Mount holes: standard 16.5 & 19.5
We have done extensive testing on this motor and are really
excited about putting it into action in some of our IFO's, Tiger Moths (can you
say 3D Tiger Moth), PT-17, and any plane 12 oz's or less should go 3D !
The motor has been tested and works well with two and three LiPo
cells in series. I like them on three LiPos !
A two cell runs between 6 and 8.4 volts. A three cell runs
between 9 and 12.6 volts, depending on the state of charge. See the Tech Chart
to figure out what type of performance you'll get with these motors.
