What motor

[dheaton]

I have an old kit plane that says it needs a .05 can motor w/8-4 apc prop. Now I don't understand any of that. Can someone please tell me what motor this is equil to?
I need this motor for an Electric Scout. Like I said it is about 20 years old and I am just putting it together now. Motors have changed allot sense then I suppose so I am just trying to figure out how all this works.
Also do the motors come with a speed controler or something? How do the motors hook to a servo? Sorry for all the questions but I am clueless about all this.

Thanks

It is suggested that you need 250-300W driving an 8x4.. probably ~1400Kv.

This would do it easily on 3s: http://www.hobbyking.com/hobbyking/s...00Kv_550W.html


Yes, you'll need a brushless 30A+ ESC with built-in BEC... servos plug into the Rx in the appropriate slots (usually Channel 1 and 2 for 3-channel aircraft). The ESC (connected between the pack and the motor) plugs into the throttle channel (usually Channel 3).

Hi A .05 brush motor is Equall to a 400 brushless motor, here is a nice motor from Heads up Rc. use a 3 cell lipo and a 30 amp ESC, 30 amp esc is a over kill, but it will last longer and stay cooler.

		Firepower 400 Sport (2830-11) Outrunner Brushless Electric Motor SKU: E-630 Price: $16.95 This item is out of stock Quantity:
The Firepower 400 Sport (2830-11) is a 1.9 ounce, 1150KV, 180 watt, 400 class outrunner brushless motor capable of producing 30 oz of thrust with a 9 inch prop. This motor is 1/3 ounce lighter than a 350 brushed/geared motor, but provides almost twice the thrust! The Firepower 400 Sport is a good choice for models requiring 8 and 9 inch props. You might consider this motor for planes like the popular Super Cub, Mini Super Sportster, Seawind, Sig Rascal and the GWS Estarter, Beaver, P-38, Corsair, Mustang and Formosa. By choosing the appropriate battery and propeller, the Firepower 400 Sport is an excellent choice for dozens of mid-size parkflyers! Good prop choices for the Firepower 400 Sport are the GWS EP9050 for a nice combination of speed and thrust, and the GWS HD8060 for maximum speed. If you're after scale looks on a warbird, consider the GWS 8040x3 and GWS 9050x3 3-blade props. Good battery choices for the Firepower 400 Sport are the Power Up 11.1v 1300 20C, 11.1v 1650 20C and 11.1v 1800 25C Lipos. I recommend using the Power Up 20A or Power Up 32A ESC with the Firepower 400 Sport. If you need a brushless motor that is the same size and weight, but uses larger propellers, please check out the 2830-09. The Firepower 400 Sport comes with 3.5mm male connectors installed, and female connectors and shrink tube are included. MOUNTING OPTIONS:TheFirepower 400 Sportcan be mounted in front of a firewall using the 2800 series 'X' mountand the 2800 series rotor end prop adapter, which are included with the motor. You can also mount it behind a firewall, and a 3.17mm prop adapter can be purchased to mount a prop on the motor shaft. The GWS Plastic Outrunner Mountcan be purchased to mount the Firepower 400 Sporton a 10mm stick. Propeller test data for the Firepower 400 Sport with a 3-cell Lipo battery: 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. GWS EP9050:30 ounces of thrust at 16 amps. Excellent prop for this motor. GWS EP9050x3 3-blade:32 ounces of thrust at 17 amps. Avoid constant wide open throttle. GWS EP8040:23 ounces of thrust at 10.5 amps. GWS EP8040x3 3-blade:24 ounces of thrust at 12 amps. Good choice for scale looks. APC 8 x 4E: 24 oz thrust at 14 amps. GWS HD8060:24 ounces of thrust at 15 amps. APC 8 x 6: 24 oz thrust at 18 amps. Exceeds recommended maximum amps. APC 7 x 6: 21 oz thrust at 12.5 amps. Propeller test data for the Firepower 400 Sport with a 2-cell Lipo battery: GWS EP1170: 24 oz thrust at 15 amps. GWS EP1060:20 ounces of thrust at 12 amps. Please be aware that the battery used can make a tremendous amount of difference in the performance of brushless motors. The above data was obtained using batteries in good condition that were fully charged. 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. Other factors, such as ESC timing and variations in actual motor KV can affect the performance of brushless motors as well. We recommend the use of a Watt Meter to test the current draw of your particular power system, especially if you plan to use a prop that pushes the motor near it's maximum amp rating. Firepower 400 Sport Specifications: Weight = 1.9 ounces (54 grams) Diameter = 1.1 inch (28 mm) Motor length = 1.2 inch (30 mm) Shaft = 1/8 inch x 0.5 inch (3.17mm x 13 mm) Voltage = 7.2 - 13.0 Current = maximum of 17 amps or 180 watts for 30 seconds KV = 1150 Mounting holes are spaced 16mm and 19mm on center and are tapped for 3mm screws.

If you want more power, use a 480 Motor. if your going to be flying off grass or if you want to use floats.

Firepower 480 Sport (3530-11) Outrunner Brushless Electric Motor SKU: E-640 Price: $19.95 This item is in stock Quantity: The Firepower 480 Sport (3530-11) is a 2.6 ounce, 480 class, 260 watt, 1100kv direct drive outrunner brushless motor capable of producing 40 oz of thrust from a 3-cell Lipo battery. It's a good choice for sport planes weighing 18 to 45 ounces, and 3D models weighing up to 28 ounces. The APC 9x4.5E is a good all around prop for this motor. The APC 10x5E prop can be used for maximum thrust, and the APC 9x6E is a good choice for high speed models. We suggest using a 3 cell Lipo battery that is rated for about a 35 amp continuous discharge (or more), such as an 11.1v 1300 30C to 11.1v 2200 35C. We recommend using a 30A to 40A Electronic Speed Control (ESC) with this motor. The Firepower 480 Sportweighs less than a 400 speed brushed/geared motor, and it can be used in many applications calling for a 400 to 600 brushed motor. Keep in mind that the Firepower 480 Sport is a 35mm (1.4") diameter motor, so you'll want to be sure you have room to mount it on your model. Should you need to use a 28mm diameter motor, take a look at the Firepower 450 Sport (2836-11) and see if that will do the trick for you. And if you need a brushless motor that is the same size and weight as the Firepower 480 Sport, but uses smaller propellers and provides higher speeds, please check out the Firepower 480 Speed (3530-14). The Firepower 480 Sport comes with 3.5mm male connectors installed, and female connectors are included. MOUNTING OPTIONS: TheFirepower 480 Sportcan be mounted in front of a firewall using the 3500 series 'X' mount and the 3500 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 picture below shows the motor with the 'X' mount and rotor end prop adapter attached. Propeller test data for the Firepower 480 Sportusing 3-cell Lipo batteries: It's a good idea to balance all propellers with a Propeller Balancer before using them on this motor. Rotating propellers are dangerous. Please stay clear of prop and wear eye protection. APC 10 x 5E: 39 oz thrust @ 23 amps GWS DD1060: 40 oz thrust @ 22 amps 10 x 6 folding: 35 oz thrust @ 18 amps APC 9 x 4.5E: 35 oz thrust @ 18 amps GWS 9050: 36 oz thrust @ 18 amps GWS 9050x3 3-blade: 38 oz thrust @ 21 amps APC 9 x 6E: 36 oz thrust @ 21 amps GWS 9075: 32 oz thrust @ 25 amps Please be aware that the battery used can make a tremendous amount of difference in the performance of brushless motors.

A 3 cell 2200 mah lipo will work well, the esc plugs into the radio receiver as does the servos, if your going to be using a 2.4 radio, use a seperate UBEC to be on the safe side, if using 2.4, use a full range receiver and not a parkflier receiver. Take care and have fun, Chellie
