In choosing a motor one has to consider certain criteria, for instance during average loads (e.g. hovering flight) revs should reach 70% of the maximum available.

I’ve just started electrification of a scale Seaking helicopter originally earmarked for Vario Gasser mechs. I bought the Plettenberg HP 370/40/A2 Heli and the Schulze 40/160 ESC. Due to a bit of a mixup with orders, I have just got 3x Tanic 4S2P 7300mAh to run at 12S2P and these were closely followed by 4x TP 3S4P 8000. Should have enough for a while!! I will be using a 5 blade head with 1600mm disk and expect the weight to be 8 to 9 Kg but that is just a guess. The fact that the fuse is almost fully enclosed I am a little concerned about the cooling of the motor. I want a head speed of 1400 and using the stock Vario gears/pulleys I currently have a reduction ratio of 9.09:1. What would be, as near as possible, an ideal motor speed to aim for? I can then use that number to try a different gear/pulley combo.
