Have any of you measured the full power current with these props? I use an ammeter to check current draw every time I try a different prop.

I maidened my E-flite Mini Stick yesterday using the E-flite 450 890KV outrunner with 2100 mAh 3 cell lipo and with a APC 10x4.7. The motor was drawing about 16 amps at full power. An APC 9x6 also drew about 16 amps at full throttle. The literature that came with the motor rated it at 12 amps continuous and 18 amps for a 15 second burst. With these props already taking the motor current close to the abuse zone, I didn't even try the recommended 10x7 prop.

The power rating of an electric motor depends a lot on your definition of abuse.
