I'm running the Turnigy G 46 in a Hangar 9 P-51 with robart retracts. It has a Redbrick 125 amp esc with a Zippy 5800 mah 5 cell. I then duplicated the setup in the HobbyKing 1600mm P-47 foamy. Both have Master Airscrew K Series 16x8 props and they both haul the mail. The sound from the prop is great. The P-51 originally flew with a .46 evolution nitro then an .60NX nitro. The G46 out performs the .60 NX motor. I also have a Pulse 25-e from eflite. I run a 4 cell 3200 mah battery with an E-flite power 25 motor. I then purchased a Turnigy G25 and replaced the E-Flite. Same performance. All three motors run cool as does the battery and the esc's. I get about 6 minutes of heavy butt hauling flying out of each setup. Can get 8 minutes with throttle management.
