I noticed it really doesn't seem to matter what heli these are on, those balls are "justa" bouncing and a swayin in the wind! I'm going to try and find something that maybe lightweight and "oval." If I could find this and make a gear where as the oval is facing vertical, it could be more resistant to vibration. ya think? Orrr what about and extra wide set of landing skids. That may be even better and more stable.

Maybe some of you guys who have no life can come up with something
