Welcome to Wattflyer Bob. Have you checked it running with a watt meter to see what it's actually doing? What prop is on it? Do you have a link to the motor?

sounds like your drawing way to many amps, if you have a prop thats bigger than a 6x4 or 5x5,that may be the problem, invest in a wattmetter, it will save your motor,esc and lipo.

Oh Yea, Way Way to much prop being a 9x6, you are drawing way to many amps, thats causing the motor to get hot and burn up. what plane do you have the motor on, we can help you to find a much better match.

If you need to turn a 9x6 prop, this will be a much much better motor, its best to use outrunner motors on larger planes. if you have any questions on a power setup for your plane, give Jeff at heads up Rc a E Mail, he will get you the best power match for you plane, A lot of people here buy from Jeff, he is the best of the best when it comes to service, prices and good motors on a budget Tell Jeff that Chellie sent you Take care, Chellie

TP 9 x 6E: 33 oz thrust at 18 amps.

this will give you a 1 to 1 power ratio, thats very very good

the scorpion 2212-22 motor is a 1175 KV motor, 28mm X 25mm, the higher the KV the motor is the more amps they draw, 2200 kv is the rpm per battery volt. so its a high RPM motor,

use this motor From Heads Up Rc with a 9x6 prop. for a 1 to 1 power ratio, its a little more power than what you need, but you can always throttle back, and its nice to have the extra power to get you out of a bad situation Hope that helps, Chellie

TP 9 x 6E: 33 oz thrust at 18 amps.

http://www.headsuprc.com/servlet/the...0-Sport/Detail



Power Up 450 Sport Outrunner Brushless Motor



The Power Up 450 Sport is a 2.5 ounce, 1100KV, 450 class outrunner brushless motor that works well on many medium to large size parkflyers. It will produce up to 37 ounces of thrust when using a 3 cell Lipo battery and the GWS 1060 prop. This motor includes an X mount and prop adapter!

The Power Up450 Sport is a good choice for a wide variety of models. You can choose to have moderate performance and light weight using a GWS EP9050 prop and the Power Up 11.1v 1300 20C or 11.1v 1500 20C Lipo battery. If you're looking for high speed and maximum thrust, try the GWS EP1060 prop and the Power Up 11.1v 1800 20C Lipo battery. I have the Power Up450 mounted on a 43 inch wingspan Decathlon. The performance is exceptional, with unlimited vertical at full throttle, and excellent efficiency at 1/2 to 3/4 throttle.

I recommend using the Power Up 32 Amp ESC with the Power Up450 motor. All Power Up Electronic Speed Controls come with 3.5mm female connectors installed, and male connectors are included for your motor.
MOUNTING OPTIONS: The Power Up450 includes an X mount that makes it easy to mount the motor in front of a firewall. It also can be mounted on the front of a GWS Plastic Outrunner Mount, making it a drop-in fit for many planes with 10mm sticks. The picture below is for reference only. THE STICK MOUNT MUST BE PURCHASED SEPARATELY.

A 4mm Prop Adapter is included for mounting props.

Propeller test data for the Power Up 450 when using a 3-cell Lipo battery:

Rotating propellers are dangerous. Please stay clear of prop and wear safety glasses.
TP 10 x 5E: 38 oz thrust at 20 amps.
GWS EP1060:37 ounces of thrust at 19 amps. Good choice for maximum performance.
GWS EP9050:32 ounces of thrust at 15 amps.
GWS 9050 3-blade:34 ounces of thrust at 17 amps. Nice for scale looks.
TP 9 x 6E: 33 oz thrust at 18 amps.
GWS EP8040:22 ounces of thrust at 9 amps.
TP 8 x 4E: 23 oz thrust at 12 amps.
TP 8 x 6E: 24 oz thrust at 17 amps.
GWS HD8060:23 ounces of thrust at 14.5 amps.

Propeller test data for thePower Up450 when using a 2 cell Lipo battery:
GWS EP1170:27 ounces of thrust at 15 amps.
GWS EP1060:21 ounces of thrust at 11 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.
Power Up 450 Specifications:
Weight = 2.5 ounces (71 grams)
Diameter = 1.1 inch (28 mm)
Motor length = 1.35 inch (34 mm)
Shaft = 4mm x 0.5 inch
Voltage = 7.2 - 13.0
Current = maximum of 20 amps for 30 seconds
KV = 1100
Mounting holes are spaced 16mm and 19mm on center and are tapped for 3mm screws.

That PowerUp 450 is simply a re-badged Suppo A2217K-8T (1100Kv)... here is what it can do:

In general, without getting technical, when your motor gets scorching hot and smells, that's a sign that you're running it way too hard.

Sorry, I forgot that I had done no-loads and had DriveCalc compute Kv, Io, Rm etc for all the Suppo 2217's.. I have the data on MS Word files, but haven't scanned 'em to jpeg yet.

The Suppo A2217K-8T is actually ~1175Kv.
