15050 RPM @ 7.4V gives a KV of over 2000 RPM/V, not 1300. I would have thought a company the size of GWS could get these basic specifications correct. Also could GWS accurately measure and publish the motor resistance please? Without that we don't know if the unusually high Kv (for an outrunner) is caused by a low wind or poor magnets.

Neil,

We will have the motors and controllers in on Monday. We will be testing them and posting results on our website, just like we did for the hurricane motors. Results should be up by the end of the week. Then we will all know how they perform.

At the prices offered on the motors and controllers, I am sure there is a market for them and they may just blow away a lot of the competition.

Thank you Jeff,

I am not in my office now. I just finished HK show. Will be in the office next week. Neil, I will check on this. Thanks for letting me know.

I will also post 2 new photos --- for 2 bigger brushless motors.

Will also have a kit --- to program the ESC.


Ray

[tonytek]

I have just purchased one at the AMA show in Ontario, CA. The motors are selling out at $15 each, one to a customer.
One question. Is the shaft reversable?
Thank You
Tony S.

[RAY GWS]

Hi Tony,

No, not at his moment.

But good thinking.

We are working on this.

What we will have are 2 more motors to come and 25A, 35A ESC plus

a kit can be used to program ESC. ---- the one at the bottom -

( actually product may have a different case/housing.)

Please stay with GWS and give us a little bit more time.

When I have more info, will post here.

Hi Neil,

You are right. The KV is 2050. Thank you very very much.

[Neil Stainton]

Thanks for acknowleging me. If GWS doesn't have the skills to measure a motor accurately I could do that for them.

[eflyer1234]

This info may be hard to read, it looks better when posted on our website. The first set of numbers is for 2 cells, second set for 3 cells.
the columns are prop, rpm, thrust in oz, tourqe in oz/in, current in amps, power in (watts), shaft power in watts, efficiency, shaft horsepower, and pitch speed.

Mike
I am not in my office. I will post more detail about all the feature.

I am sure many flyers will love it. I have seems many version on PCs.

But with this programming board, you can do it at flying field.

Mike

switch inbetween Ni-Mh and Li-PO

With auto detection, will be able to use

NiMh battery 6-16C
LiPo 2C-4C

When you select LiPoly cutoff - what is the cutoff voltage used per cell?

Mike

[RAY GWS]

3.1 Volts

[pda4you]

2.75 V

That is too low, especially for the newer generation cells.

3v is what most consider to be safe and is the standard.

Hi Mike,

Thank you. Will check on this.

2.75 V


Ray;

Until you raise this to 3.0V/cell we will steer our customers away from your controllers. Please PM us once the change has been made so we can inform our dealer network.

I will check on this.

I also check castlecreations and hacker manual.

None of them are using 3 Volts.

any one have more info?

Thanks.

I set my LVC to 3.2v per cell. Which is why I like pheonix controllers.

[RAY GWS]

I will be better that you decide what cut off point you want.

GWS BL ESC will cut off at 3.1V, but it’s not a 100% cut off, the ESC will cut to 50% power to notify the pilot he has reach the low voltage stage. ;)

Much better 2.75v is much too low.

I gotta say, Looking over the manuals that Ray posted it looks like GWS has really improved the translations. Those manuals are extremely easy to understand.

[zzonie77]

Ray ...
Where can I purchase the connectors that go with the ones you have on the motor?

Rus

[RAY GWS]

Hi Rus,

To save your shipping cost, how about ask one of our dealer to order for you.

Or you can email to service@gwsus.com to ask help on this matter.

Please also email me fly@gws.com.tw if you are in a rush.

I have completed (25) 10 minute flights in 85 - 90 degree F air temperatures on a 3 cell 450 Etec lipoly battery. 25% of each flight is WOT. After each flight the motor temp is checked with only a 5 to 10 degree rise above ambient.
Prop: 7035 GWS
Plane: GWS Pico Stick (modified for acro flight). Weight 7.5 oz (no battery). Vertical performance, 100' diameter loops, tight snap rolls.

My first flight was on the recommended 2 cell battery. I brought the plane back in after 15 seconds due to the sluggish performance. Changed to 3 cells and the plane came "alive" ....... exciting performance.

The motor design provides excellent cooling even in our hot desert conditions. with no heating problems.

Awesome performance from a $15 motor !
