The avrocar project hasn't been very successful with the initial design. There was something very wrong with center of gravity that needed to be addressed. I couldn't eliminate the toilet bowl effect with my existing and new solutions that I tried.
Made a revision on the body to fix the center of gravity problem. Flies way better now and the toilet bowl effect was reduced. However, it didn't disappear. Below videos is an outdoors test, which started good but didn't end very well, with the unit losing the flight capability with a fatal wobbling.
Damage was minimal and the unit is fixed. Next step is switching from 1 battery to 2 batteries, increasing the weight and therefore increasing the effectiveness of the thrust vectoring.
All challenges resulting from the characteristics of this unique design is being magnified as the size goes smaller
Great experience to learn the limits of the design!
