Motor selection: Avroto 2814-11S, QC-3328, and Torxpower 3536 Pro?

I am currently using Avroto's and have no complaints. I am just curious about the two new motor's on the block and how they compare. Personal experience opinions would be great. Also, can anyone explain why the QC-3328 is listed as a good bit smaller compared to the others but has about the same specs which includes weight. How can that be?

Torxpower 3536 Pro - http://www.quadcopters.co.uk/?PageID=ShowItem&Item=3536PRO&Desc=Torxpower 3536 Pro (Short Shaft)

I am really liking the Torxpower's specs and current price.

Thanks for your thoughts!

I was pretty sure these were all the same motors. They sure do look exactly alike. I guess they share the same housings but have slightly different internal specs and QCs'? I too am very happy with my Avrotos, even though they just raised the price on them, dang it!

As far as I am aware they are ALL made by the same manufacturer. When you order hundreds you can choose the components that suit your application. The TorxPower ones are to Geoff at www.quadcopters.co.uk 's specification. Quadrocopters in the US are basically he same just a slightly lower KV rating... or was it the other way round!

Quadrocopters measurements are I think the stator size and not the bell size.. but again I just got up and my brain is still rebooting!

Geoff just took delivery of another motors size yesterday which is the 2217/20 equivalent TorxPower motor..

All from the same manufacturer, interesting. So, design wise they are all the same except individual components may differ. Correct? I wonder what the quality of individual components between the three is.

I thought I would save folks interested in these the trouble of going to each site to compare by putting a spreadsheet together. But I have ran into a question about the listed specs.
Avroto lists 'Current Capacity: 22A/60s' while Quadropower lists 'Load Current: max. 30A' and 'Maximum load current. (15 sec): 50 A' and Torxpower has 'Load Current Max 30A (50A bursts 10secs)', I can't decided what the Avroto spec is trying to tell us since it has the 60 seconds in the value?

Thanks,

Shawn

Avroto And TorxPower are the way to go. Either is OK. QC is so much expensive. As far as I know they are manufactured by the same company, Tiger Motors.

I would continue to use motors what I already have currently. In case you need
