This is the current setup with the leopard 4082 motor.

Leopard 1600kv 4082 running on 5s. 80km/h with Octura x447. Average draw is 50-70Amp, 150Amp peak.
Btw, i would strongly advise to replace battery pads. After last fly my 5000mAh 5s packs ripped both pads off.
These pads glued to small plywood stands. Glue is low quality; I removed what’s left of it from the hull pretty easily. And part of pads simply exfoliates.
