I replaced my Batch1 hoop net with a super strong all metal version without adding more than a few grams. The enclosure cover just about the entire hoop. It is impossible to reach back to the propeller by mistake. Already flown and tested. Worked well and so are my homemade four anti-torque fins.

Can you tell me more about the anti torque fins?
Are they 3d printed?
Do you see noticeable drag increased sink from the drag?
Could you share a file so I can print a set?
Hi Dennis, I tried 6 and then 4 fins. 6 were more efficient but 4 also worked to slightly lesser degree. Frankly I did not feel any difference in sink maybe because of the way I fly, low to the ground - a lot of proximity flying but without pulling any stunts. I accelerate in short bursts to prevent the cage from touching the waves (beach), grass or tree tops.
Do not laugh but I made them from my kitchen ceiling fan which I had to replace. Instead of wasting them, I reshaped them and attached them to the spars. https://www.youtube.com/watch?v=zh6jA74F7oo&t=181s
However, I realized that they kind of were parasitic in heavier full throttle right turns because they were trying to straighten the SP opposite to the turn I was making and it felt kinda bizzare so I removed them altogether. I am sure there would be a good compromise to make, fine tuning the design, finding the correct fin angle, fin height on the spars, etc…
