LRK wind help requested please

I am currently building a motor with a 12 pole stator, and wish to find info on LRK style winds. I have a desire for a very high tourque motor, to swing a large prop. I hope to do this on 2 cells. Oh, The motor is about a 30 mm stator, and I am using N-50 mags. I am sorry if I am asking an old question, but this is my first LRK, and I could realy use some direction on the wind pattern.

Thanks

Walter

www.powerditto.de
-> 'English'
-> 'winding schemes in pictures' (under 'Tools')
-> 'Variations for the 12 slot stator'
-> first picture, terminate in 'wye'

The same winding diagrams in drawings:
www.mfly.de
-> technisches
Use the last one, but only wind 6 out of 12.

Torque comes from:
1. strong magnets (volume and strength)
2. many magnet poles (14 or 16 better than 10 for your stator)
3. greater 'leverage'/diameter (bigger stator)
4. more turns
5. higher current
6. gearing
You will need to find the 'magic balance' that gives you what you want.
