how many cells on gws?????????

[jason stevens]

I am curious as to how many cells I can run on The gws s1 motor.I recently purchased one from balsa products and also got the 8x6prop that they recommend.I WAS Running it on a 7cell 280mah pack and about 4 minutes into the flight the motor toasted. was this too much, or should have I used the stock 10x4.7prop? Really confused and I hate to buy another before I figure this out.

Funny... I just had the same experience this weekend with a GWS replacement motor ordered from balsa products. I was running the bigger prop that you mentioned. I'm begining to think we just got part of a junky batch of motors? I'm running a Castle Creations Pixie 7p, and the same battery pack... Does anyone have an idea?

I've given up on the GWS motors. While some have reported outstanding results with the carbon brush motors, the two I've had were junk - toasted in no time flat, and I wasn't even pushing them. It sounds like GWS sent out a bad bunch of motors recently, and maybe there will be an up cycle, but I'm not going to take any chances.

I bought a GWS carbon motor from Balsa Products about six weeks ago. I'm running it on 8 Nimh cells direct drive. When I started hearing all the problems with these motors I figured mine was going to toast in nothing flat. However, that was not the case, I have about 20 flights on mine so far and most of the flights were at almost full throttle since the plane is a little under powered.

I really hope GWS figures this out soon. Their motors are potentially an outstanding product.

I'm not sure what to think either... I have a few GWS motors that run great. I've never had a problem with them, but the one I just purchased cooked itself in less than two 10min flights. Are there any good direct replacement motors that will work in the standard GWS gearbox? Any advice is apprieciated.

[jason stevens]

has anyone tried the gws 280 design? i've been thinking about slapping one of those suckers on my picostick fd. I can almost hang off the prop now and I can do some basic aerobics with it stock, but I bet it would scream on a geared 280 setup.

GWS IPS system are specially redesign for Indoor & park flyer to be operated at 7.2Volts. Do not think this motor as other which size look same from outside. They are completely different at interior.

Most people who listen to other experience from whom use a similar size coreless gear drive. Those are operated at 9.6Volts. However, if you are doing so to GWS IPS regardless that we strongly mention not to use over 7.2volts, you might possible burn GWS motor easily and make a bad comments!

Another fact, you have to choice right loading on each different gear ratio. GWS IPS has offered 8 different choices to meet your demands. Think about that you are driving a car, you will never use a last gear shift to clamb up hill!?

Pls go to GWS web-site: http://servoman.hypermart.net/english

Hope that you will find a lot of information needed for use GWS IPS at right way.

For heavy load flyers, GWS also supply a heat sink to let motor run cooler. Here is a samll tip for you: Most DC motors run over heat will decrease it torque about 1% every 4 degrees F increased! More current will be comsumed!

GWS will be glad to provide you the necessary tech support to use GWS products at right way.

Just a note to the CEO of GWS, I think you have a really wonderful product, priced right with all the things us slowflyers are looking for. As for frying your motors, you need to listen to the gentleman and his comments about proper voltages for these motors. I've been flying two GWS motors for sometime now. One on a Cox P-51 Conversion using a GWS A motor with 6 cell Nicads, the other a Tiger Moth with stock motor, 9x7 prop and 6 cell NMHS with flight times of over 12 minutes! I love my little Tiger and will probably purchase the new Ducted Fan A-10 when it becomes available soon!
Keep up the good work at GWS, and thanks for making Eflight more affordable and fun!

Note to GWS

I think it's wonderful that the CEO of GWS would take the time to respond on this board. That shows a company that is really interested in their customers.

However, in my opinion your web presence leaves a lot to be desired. I got two pop up advertising windows for unrelated items, one of which refreshes every 30 seconds.

A world class company should have their own site. Not a "freebie" site with advertisements. I make it a point to not visit such sites.

Houng-win Lin,

Thanks for posting on this board. Here's an idea. Over on the E-zone bulletin board Larry from Hitec creates at thread periodically called "Ask Larry at Hitec". Since your GWS products are quickly becoming staples in our hobby, perhaps you could start a thread "Ask Houng-win at GWS". You could post information about new and upcoming products there. Bulletin board members could post questions to you there and you or someone from your company could answer them.

In terms of battery cells and GWS motors, here's my two cents. I have a J3 Cub stik and a Tiger Moth. Both of them I've been flying with 7x110 NiCD battery packs. I knew that I was using more cells than GWS recommends, but I took the chance. I figured that if I burned out a motor I'd have to buy a new one and would remove a cell from the battery pack. So, far, ok. I have some new 8x270 NiMH (because of slightly lower voltage per cell) packs that I intend to try. Again, If it turns out I burn out a motor, I'll have to buy another. I'm the one who took that chance.

We all like to experiment and we all want more power. Not all motors have the tollerance to accept more voltage or smaller props, or both. Some of us might get a slightly better motor and be able to abuse it more, others might not be so lucky. There Aint No Such Thing As A Free Lunch (TANSTAAFL). We can all fly with GWS suggested battery packs and props, but slower than we'd like. Or, we can ignore the GWS suggestions and fly with more power, but at the risk of toasting the motors.

Agreed, www.ezonemag.com (http://www.ezonemag.com) is the place to be for electric flight, GWS products are ALWAYS being discussed there.

Daer Gordon,

Thanks for your kindly understanding about how to use a GWS motor.

I like to remine you my last post which concerned overload & heavy load flyers' solution about heat built up.

For heavy load flyers, GWS also supply a heat sink to let motor run cooler. Here is a samll tip for you: Most DC motors run over heat will decrease it torque about 1% every 4 degrees F increased! More current will be comsumed!

One of friend who fly Tiger Moth with heat-sink, he reported that motor even last 76 hours. :eek:

I hope USA flyers can get this little wounder
heat-sink from dealer. This a great improve to IPS motor performance, run cooler with more constant power, also great for extend motor life duration! ;)

[gjohnson]

Just a clarification. I'd suggest that GWS start a "Ask GWS" thread on RC Microflight's BB (this one). The reason is that this site is devoted to the smaller electrics that GWS targets their products at. As such, this is a more natural home to such a Ask GWS thread.

You can get replacement motors for GWS gearbox's at Goldmine.
They are the same size, shape, weight and output as the GWS.
Black backplate, turns 3x2 prop at 14500 prm on 6 nicads.

After working with the IPS 180 series motors a good little bit, I have concluded that it is the current that is a killer and not necessarily just the cell count. With all due respect to Mr. Lin, I would like to see more information about this issue. I have been flying an aerobatic model with the IPS DXA metal brush motor on 8 cells for some little time with excellent results. The motor is propped to draw no more than 2A static, and this drops to about 1A at full power in manuevers. The other helpful factor is "flying" the throttle, so that my periods of full throttle rarely exceed 10 seconds. At the end of a flight, both the motor and batteries are relatively cool to the touch.
Cheers, Dave Robelen
