I did some static testing of the stock power-train this afternoon.

The 580kV motor on 4S was drawing a steady 55A at full throttle. This means about 825W with the voltage sagging to roughly 15V under load. This also means the stock setup offers a bit over 160W per 500g which is healthy.

I then decided to warily run it up on 5S - bloody hell - it was roaring at 50% throttle and drawing 40 A at that point, but with the higher voltage the power transferred was also about 800 W. I didn't go any higher than about 60% throttle because it was becoming a wild beast and I would like to check the integrity of the motor mount before I go any further. I'll have to also check the motor specs to see what it can tolerate. I've put my plans to run it on 5S on hold for the moment because I want to get another prop and hub assembly and install some shims under the trailing edges of the blades to reduce the pitch a little. A work in progress ...
