I used this setup in two planes last summer. Worked well. Though I had one esc turn to charcoal. Never knew if it was the motors fault or the esc. Motor let out a high pitch squeal right before it smoked. However Hacker said the motor was ok?? Anyways used a 22x12 apce. I'm converting all to the 85-90 amp esc's for the extra head room this year. You'll get around 60-70 amps with this prop depending on batts and which rotor is in the C50.

I was getting 60-62 amps.
