Hello guys..!! I recently started making a rc hovercraft. Everything was fine but i am facing some problems with the following...
1.The hovercraft is bending(some times it even flips) left and right
when making respective sharp turns.
2. It is good and stable on almost plain surfaces... but it wont move an inch when it is tested on grass, sand, etc.. or any other uneven surface..
3. I saw in some videos when there is an obstacle their hovercrafts are hovering above them nicely. But mine colliding with obstacles why??
I know the reasons for above 2 problems( I think)
1. Centre of gravity is high and skirt design is faulty..
2. The skirt material is plastic. So, it might have some friction related issues..
How to overcome these problems.
How to design the skirt perfectly..
