Perfect, I made one :)
I only use the top part up side down.
Used 8520 motors
The old hubsan Rx board fits perfect.
FPV tx03 camera.
Printed in petg 20% infill, 0,1 layer height.
Not the prettiest but can be assembled with only elastic bands in under 10 minutes.
Flies well outdoor, approximately 7 min flight time on 600 mAh battery.
