The Firepower 450 Slofly (2836-09) is a 2.6 oz, 900KV direct drive outrunner brushless motor capable of producing 36 oz of thrust from a 3-cell Lipo battery. This is a '450 class', 200 watt, brushless motor that weighs less than a speed 400 brushed/geared motor, but provides about twice the thrust! It is roughly equivalent to .10 to .15 size two stroke glow engines.
The Firepower 450 Slofly is best used on slow to medium speed planes. I installed this motor on a GWS Slow Stick, and used the TP 11x5.5E prop and Power Up 11.1v 1500 20C Lipo. The Slow Stick climbed straight up easily, and the top speed was very manageable. Many people add a camera mount and strengthen the wing of the Slow Stick for AP work, and I suggest using this power set up to handle the extra weight. I recommend using the GWS Plastic Outrunner Mount to mount the Firepower 450 Slofly on the Slow Stick.
If you have a 3D model in the 16 to 26 oz range, the Firepower 450 Slofly will do an excellent job using using the same power set up. And if you want a little more speed for a sport model, use the GWS EP1170 propeller.
Good battery choices for the Firepower 450 Slofly include the Power Up 11.1v 1300 20C,11.1v 1500 20Cand11.1v 2200 20CLipos.
I recommend using the Power Up 20A or 32A ESC with the Firepower 450 Slofly motor.
The Firepower 450 Slofly comes with 3.5mm male connectors installed, and female connectors and shrink tube are included.
MOUNTING OPTIONS: The Firepower 450 Slofly can be mounted in front of a firewall using the 2800 series 'X' mount and the 2800 series rotor end prop adapter, which are included with the motor. You can also mount it behind a firewall, and a 4mm prop adapter can be purchased to mount a prop on the motor shaft. The GWS Plastic Outrunner Mount can be purchased to mount the Firepower 450 Slofly on a 10mm stick.
Propeller test data for the Firepower 450 Slofly:
It's a good idea to balance all propellers with a Propeller Balancer before using them on this motor. TP propellers are available in our store, and are nearly identical in performance to APC props. Rotating propellers are dangerous. Please stay clear of prop and wear eye protection.
TP 12 x 6: 36 oz thrust @ 16.5 amps with a pitch speed of 35 mph.
TP 11 x 5.5: 33 oz thrust @ 14.5 amps with a pitch speed of 36 mph.
APC 11 x 5.5E: 33 oz thrust @ 14.5 amps with a pitch speed of 36 mph.
GWS EP 1170: 34 oz thrust @ 15.5 amps with a pitch speed of 44 mph.
TP 10 x 5: 27 oz thrust @ 12.5 amps with a pitch speed of 36 mph.
APC 10 x 5E: 27 oz thrust @ 12.5 amps with a pitch speed of 36 mph.
GWS EP 1060: 27 oz thrust @ 11.5 amps with a pitch speed of 43 mph.
APC 10 x 7E: 25 oz thrust @ 14.5 amps with a pitch speed of 46 mph.
GWS HD 1080: 25 oz thrust @ 15.5 amps with a pitch speed of 50 mph.
The above data is a result of my own testing using a fully charged 3-cell 2250mah 20C (45 amp) Lipo battery. Thrust and amp draw may be less with the use of batteries rated at lower amp output, and slightly more using batteries rated for higher amp output.
