ABC geeft wel meer cogging (loopt iets minder vloeiend) en daardoor meer geluid.

Beter, gebruik zo dik mogelijke draad, of twee parallel. Gebruik de ruimte tussen de tanden. Hogere efficiëntie, lagere temperatuur, meer vermogen.
Higher efficiency does not only mean that the motor makes better use of the batteries' power, it also means the motor is able to handle a higher power input before hitting its maximum temperature mark i.e. a higher power/weight ratio.
An example:
Say the motor has an efficiency of 70% and it can handle 50Watt input. That means it can get rid off 0.3*50=15Watt excess heat. Now, by cramming in thicker wire (and/or using better stator-iron, segmented magnets), efficiency increases to say 75% (I'm a bit optimistic here). The motor's ability to loose those 15Watts has not changed (by radiation, convection and conduction). This means the motor now can handle 60Watt before it hits the 15Watt (0.25*60Watt) losses mark. An efficiency increase of 5% gives an increase in the power to weight ratio of 20% (from 50Watt to 60Watt). That's why efficiency plays such an important role, in any motor design: efficiency governs maximum power.
Go to your local friendly motor/transformer rewinder/refurbisher or repair shop. Excellent quality, all gauges, penny stuff, you'll probably get it for free if you bring your motor along. They love it when they can handle a motor without the need for a crane

And maybe let them have a spin with your plane once you finished your motor? You know, in case you need wire again for your next motor
