Good info here, should be required reading. Yes Kv is not a figure of merit, just a characteristic. But is it "Kv", "KV", "kV", or "kv"?

Excellent explanation of the value of bigger windings. One of the characteristics of rewinding with fewer turns of larger wire is that the RPM per Volt (kV) goes up, which is not always desired for...

Yes CA is tricky, often brittle, but there are many places where it is great, like all the ribs in a wing. With CA and kicker, you can build a 1/5th scale plane in just a few hours.

Your baking soda is an excellent tip. I find I can use CA without the "kicker" if I use baking soda, or just a spritz of water mist for a joint that doesn't need the filler and strength. With the...

Yes, that makes sense. I know with welding transformers, the "Hypersil" units are equipped with high silicon steel, and the core is wound with this steel in sections so thin you can hardly see them...

Thank you, ron van sommeren.

You really put the value of fat wire in perspective. Since the motor can get rid of only so much heat, make sure the portion of power that is converted to heat is...

When you get the kits at GoBrushless, it includes lots of wire, even in three different colors, which is thoughtful, but not necessary, you can only wind one (of three) phase at a time...

Never thought about the prop shaft...hmmm
It is true that my Go Brushless has survived a lot of crashes with no bent prop shaft. My Chinese motors are in a boat right now, so may be OK. Good...

shotgunsmitty,
My experience is limited to my first two planes, a Miss Hangar One, and a stripped down second generation of it.

Make sure you use an electric style prop. APC props are my very favorite for fuel, but did not work well for my electric, and delayed my progress trying to get the 16 oz thrust I was...

bz1mcr,

I agree that building your own motor is very rewarding. I started in e-flight this way, and I learned a lot more than I would have with a stock built unit.

I learned, with help from...
