It is hard to find 800mah or 1300mah batteryes that can give out 50A
The test was to se how long you can go with a brushless engine.
-
2100s seem too heavy. 800mAh to 1300mAh lipos should do it plus a 1800kv motor & 13T. that should give around 3200+ rpm.

Se the end of the video there you will se the 2x 3s battery.

I don't know how you would fit the batterie in the canopy.

Hva er KV på motoren du bruker her med 6celler lipo?

The KV was 3400kv but this is way to mutch, you may go for 2000-2500kv. I have to make my own pinion to reduse the head speed. There was so mutch power that the tail belt snapped when i did a lowpas on full trottle. I had to limit the flight time to 1min to not kill the engine.
