View Full Version : need brushless motor

04-29-2006, 03:51 AM
Finally got my Cap 580 (Great Plains) in the air. Can't really say it flew. With the stock motor it was more like a controlled stall. So looks like I need a brushless set up for it. Anyone have suggestions for a reasonably priced out runner and speed controler combo? With the current set up I'm running close to 12 oz in weight.

This motor would be a great match- http://www.3dxhobbies.com/store/cart.php?target=product&product_id=41&category_id=293

Depends on weight but here (http://willstech.com/products/product_info.php?products_id=910&osCsid=ac05b31c16cce5f0e9047f12994b3bd4) are some other choices to look at. Or here (http://willstech.com/products/product_info.php?products_id=899&osCsid=186f5242b563d44f4dabbb1d521a3f3d). And here is another.

Lets see if those all work now. :)

By the way the first one will be in stock early the following week. Can't seem to keep them in stock. Have some inexpensive speed controls to go with and have had no complaints.

Reply to Paul. The motor you suggested is recommended for a 7 to 12 oz model. I am at 12 oz now and if I change to a slightly heavier model or to a bigger bat pack I would be under powered. I looked around your site and found the A20-L Kv1022. It seems that this may be a better way to go.

Reply to Debbie. Looked at the first two motors you recommended. See my response to Paul. The third one you listed may be a little too much the other way. I looked around your site also and foundthe Park 400 920 KV. This looks like it may fit the bill a little better if I go up in weight.

This would be my first brushless set up ( about time) so am still learning about power systems. I assume that the higher Kv rating would suck more amps.
Of course throttle control and prop size also affect this.

Higher Kv more power? I have heard 100 watts per pound. If you look at the watts of these motor and the recommended oz they will fly it looks like more than 100 watts per lb. I have an under powered plane now and I don't want to spend a hundred bucks and have another under powered plane. I'm just getting into this 3D foamie flying so want a set up I can grow with.Thanks for your suggestions. It gave me a good idea what where I needed to start. Thanks.

I would say look through the axi 2208 and 22/12 series motor's. I love my axi motors and i have lawn darted some of my foamies and not hurt these motors. also if you ever do break one you get a replacement for half price from hobby lobby. and by far axi's reliability speeks for itself. yes a little pricey but you will use this motor on probably many planes in the future.

The eflite park 400 outrunner is also in the power range you need, about 110watts. Will swing a 10x7 prop with authority.

There are a whole bunch of very inexpensive brushless motors/erc combos on the market. Check out BalsaProducts, TowerPro, and HiModel. The CDROM type motors run between $14 to $20, are light (but a little fragile), and the lower KV will turn a decent prop. Tremendous bang for the very few bucks.
