16 Turn Motors

I built two Komodo advanced N50 motors, both with 16T of #24 GoBrushless wire, I like the design nice motors.

The only prob. I had was the shaft on 1 of the motors kept coming loose from the bell ( i tried CA a few times), i have switched to trying thread lock instead now... will see what happens in next few runs. (edit: i will key the shaft up next time)

Also I prefer to fit the stator to the mount before winding (personal preference )

here is some data (i terminated one in delta and one in wye for the tests hoping that I would hit on the ideal for my application)

16 Turn #24 GB Wire
N50 Mags
CC PHX 25 ESC
TP 2100 3S lipo

Carbon Black prop is 5*5 (130*125) - Irvine E IRV0505CS
APC prop is 7*5E Thin electric - LP 07050E

APC 7*5 Wye 6A 65W 9000 RPM 350g thrust (WOT)
APC 7*5 Delta 10.75A 100W 10000 RPM 440g (2/3 Throttle)
APC 7*5 Delta 6A 65W 8400 RPM 300g (1/2 Throttleish)
Crbn 5*5 Delta 13A 135W 17000 RPM 430g (WOT)
Crbn 5*5 Delta 9.6A 100W 15300 RPM 350g

(grr looks messy, how do i do tables ??)

I think for my current build i will go for the 7*5 prop delta ( the wye is just a bit too low kV )and use throttle management yeah right

The 'code' tags will give you fixed pitch characters instead of proportionally spaced characters:
http://www.rcgroups.com/forums/misc.php?do=bbcode#code

Rather neat-ish, don't you think ?
Code:
APC  7*5 Wye   6A    65W  9000  RPM 350g thrust (WOT)
APC  7*5 Delta 10.8A 100W 10000 RPM 440g 2/3 Throttle)
APC  7*5 Delta 6A    65W  8400  RPM 300g (1/2 Throttleish)
Crbn 5*5 Delta 13A   135W 17000 RPM 430g (WOT)
Crbn 5*5 Delta 9.6A  100W 15300 RPM 350g

Have you tried the green loctite? I forget the # but it will hold a pinion on a 480 shaft so it should hold a bell. You may need a new shaft and or bell if there alot of wear.

I like the Kit,I wind 14 turn with the 24 G. wire that come with the kit, motor fire up with the first try, very good value for the money, however, I have a comment for the improvement of the kit. The bearing inetrference with the bearing tube is off, "the hole for the bearing is too large", the bearing just dropped into the hole, the wholething is held by the "C" clip at the back, and the "C" is too small, you need a large washer to retain the C clip inorder to hold the bearing. I thing the hole in the bearing tube should be made smaller, so that the bearing in press fit into the tube. BTW, I have the KH 278 delux kit.
Also I find the most difficult part of this DIY outrunners is not the wire winding part, it is the placing of the magnets and gluing them. I tried spacers with different thicknesses to space them out evenly, finally get them close enough but not perfect, Da V. may want to look into a better way to install these magnets.
My 2C.
Thanks.

Ways of installing the magnets have been discussed in part one of the thread. I just used my hands and judged by eye - not easy I admit, but not too difficult.
I agree about the c clip - far too small and very fiddly to fit.
