My smallest 300mm diy quad is finally ready and flown today.
The frame is able to hold any 45/36mm FC, so I voted for the KK2.0 for the first test.
I decided for the Sunnysky X2204S 2300kv motors, as they have the right punch
to twist 7″ propellers. Still, the current do not rise above ~9A, so any 10A speed controller
is suitable for this config.
The power test can be seen here:
I am using the Hobbyking F-10A escs, reflashed with Simonk code. Either they are small, light
and thin, so they comfortably fit the space between the lower decks.
I have cut some 8×4 plastic propellers to 7″ size.
Tested with 3S 2200mAh battery, the final AUW of this config w/o fpv gear is 440g,
with fpv gear it should still be below 500g.
Flight time not tested yet, but I assume it will be above 10 minutes.
The quad behaved very well despite the wind, however some fine tuning will be needed.
