The C-10 is plenty. That motor won't draw more than about 7 Amps, and the battery can't put out much more than that.

The GWS 300C motor can draw close to 10 Amps if pushed.
The C-10 ESC is capable of 12amps. I would go with the C-20 (22amp) so your not at risk of burning up the ESC. I'm using a C-10 on the same motor but am very careful of the props I use.
Never push a ESC to it's limits. If you were to, you would find that the ESC life is much shorter.

Thank y'all for the help.
Is there a formula for calculating how many amps could be pulled by the various motor, gear and prop combinations.

I wish I knew it. I simple put an amp meter between the the ESC and battery, and then play with different props/gearboxes.
Ya know Texas 1, I was just thinking. Do you have the GWS 100 or 300 motor? If you have the 100 size motor the C-10 ESC would be fine. GWS sells the Zero kit in tow versions. I was thinking You had the 300 size motor cause thats the only version I have seen available from local dealers.
Anyway, check out this sight for some good charts on motors/batt/amps/props ext. Just select the power system you what to check out. http://www.gws.com.tw/english/produc...owersystem.htm

Hope this helps, Happy flying:-)
