This is part 2 of my ideal sub 250g DJI HD design and build series, where I take the best tested motor and propeller combination and use them to build a lightweight drone with a thrust to weight ratio as high as possible, without sacrificing durability, reliability, and essential features. This video I work towards fixing identified flaws in the frame design from part 1.
