The 2712-17 is a '300 class' 1700KV direct drive outrunner motor that is a good choice for sport and scale models in the 7 to 18 oz range. We have this great little motor installed on two models, and we can't think of a better power set up for either:
-- The Sig Jenny is a foam bi-plane that is enjoyable to fly on really calm summer evenings. We installed the 2712-17 with the Power Up 10A ESC, and we use the GWS 8043 prop with the Power Up 7.4v 1000 20C Lipo. This combination provides what we feel is the ideal power and speed for the Jenny, and we love to fly this model low and slow with a beautiful Florida sunset in the distance.
-- We installed the 2712-17 in a Sig Lil' Rascal after removing the 180 geared motor. It was necesary to reverse the shaft on the 2712-12 in order to mount it behind the firewall, but this was easy to do. We use the Power Up 10 amp ESC, Power Up 11.1v 600 20C Lipo, and the GWS 7035 prop. The all up weight of the Rascal is 8.5 ounces, and this cute little plane zips around with authority. The black prop with the white spinner looks really sharp on this model.
MOUNTING OPTIONS: A firewall mount is included, and an aluminum stick mount with heat sink is available in our store.
The 2712-17 comes with 3mm prop saverand a as options for mounting a propeller, or a 3mm prop adapter can be purchased separately.
Propeller data for 3 cell Lipo batteries:
The GWS EP 8040 prop produces 20 ounces of thrust at 11.5 amps with a pitch speed of 41 mph. Yep, 20 ounces of thrust from this little motor! But you will likely fry the motor if you run at wide open throttle for very long.
The GWS EP 7035 prop produces about 15 ounces of thrust at 7.5 amps with a pitch speed of 46 mph. Excellent prop for this motor.
The APC 7x5E prop produces about 15 ounces of thrust at 11 amps with a pitch speed of 49 mph. Avoid constant wide open throttle.
The GWS EP 6030 prop produces about 11.5 ounces of thrust at 6 amps with a pitch speed of 46 mph.
The APC 6x4 speed 400 prop produces about 12.5 ounces of thrust at 7.5 amps with a pitch speed of 53 mph
Propeller data for 2 cell Lipo batteries:
The GWS EP 9050 prop produces about 14 ounces of thrust at 9.5 amps with a pitch speed of 31 mph.
The GWS EP 8040 prop produces about 12 ounces of thrust at 7 amps with a pitch speed of 32 mph.
The GWS EP 8043 prop produces about 13 ounces of thrust at 8.5 amps with a pitch speed of 31 mph.
The GWS EP 8060 prop produces about 12.5 ounces of thrust at 10 amps with a pitch speed of 38 mph.
The GWS HD 8060 prop produces about 11 ounces of thrust at 9.5 amps with a pitch speed of 40 mph.
The GWS EP 7035 prop produces about 8 ounces of thrust at 4.5 amps with a pitch speed of 34 mph.
The APC 7x4SF produces about 10 ounces of thrust at 6.5 amps with a pitch speed of 34 mph.
The TP 7x6E produces about 9.5 ounces of thrust at 7.5 amps with a pitch speed of 50 mph.
The GWS EP 7060 prop produces about 10 ounces of thrust at 8.5 amps with a pitch speed of 42 mph.
The above data is a result of our own testing using fully charged Lipo batteries.
