Idk if you tolerate your helicopter turning like crazy but to avoid it you need the tail blade, or you would need to design a double rotor that would spin in two separate directions and it would require designing a literal gearing but would look super sick too
Haha yeah that would look super sick, I might just have to give it a try to see what a double rotor would looks like. I had a bit in the original video about reducing the helicopter from spinning so much but ended up cutting it out in the edit. I've been thinking of a way to fix the issue and fingers crossed it will work on the next try 😁.
How did you decide on the angle of attack of the blades? It changes the lift. I would do something like a static fire, with the rotor attached to a fixed base and see how much lift it generates. Keep tweaking it till you find the best possible lift. Torque provided by the band decreases as the band unwinds, so experimentation is needed to find the best angle of attack for maximum hang time. Doing a static fire helps you minimise effort and wasted materials, while providing reliable data. Once you have that down, then you can solve the other problems, like providing a counter torque, etc. And lubricate your joints.
It's so cool you mention the angle of attack, this video originally was meant to be about testing different blade angles and I ended up fumbling the whole thing. I was thinking of making a video with propellers that have different angles of attack and stick them on fan power based cars and race them to see which design generates the best lift, but decided to stick to the helicopter tests. Thank you for helpful comment and I hope you enjoyed the video 😊.

Nice video! Also I'm your 100th subscriber so nice job on 100
100th subscriber! That's awesome. Thanks for subscribing😁!
Keep trying...you'll get there. Interested to see you solve this soon.
Thanks, keeping my fingers crossed.

dude try to widen the width of your blades a bit for more air coverage, they seem so thin in that video, perhaps widening them might do it
sounds like a plan, I'll test a few wider ones on the next try 👍!
