I’m not sure how you calculated the results posted, but PropCalc* shows closer to 6500 grams of static thrust and 2200 watts of mechanical power with my best guess of your components and a 10x8 prop. Pitch speed is high (good), but the prop is stalled statically, meaning you won’t reach max thrust in static condition.

Most concerning is with the motor temp having a risk of overheating depending on the exact motor used. Not so important if all you do is make two long passes. The 2200 mAh pack may be on the small side for many runs so that may mitigate the heat issue. I’d start with a 10x6 prop and judge speed and temperature from that before propping up.

* I’ve used PropCalc for years with my airboats and find it to be pretty accurate, sometimes surprisingly so. Like any modeling software it is only as good as the inputs.
