Click on the link to see 2 video's of sky bowling. The first one is with a Diamond Dust, you can barely see it because it was almost dark and it was going pretty fast.
The second video was with a Senior Telemaster.
We use 2 16 ounce plastic cups taped together at the mouth. I put some rocks in them keep the wind from blowing them over.
We plan on incorporating sky bowling in our October night flying. That should be interesting.
This was a lot of fun but definitely not a windy day fun fly activity.
