Hi All,
While my recent CATO of an E12 was spectacular, my video shows it throwing propellant over to the next pad
(15 feet?).
I read (somewhere) that E motors need 30 feet.

This is my 2nd CATO and wanted to be safe for all.

Maybe a heads-up when using a suspected CATOable motor (I know any can)

Part of the LCO job is to make sure the proper safe distance is observed for each launch. Our circle of pads have 15 feet between each so motors up to D-impulse can be fired on pad n while someone is setting up on pad n+1.

With the number of inexperienced people we had at the previous launch, I generally waited until these folks were done and back behind the flag line before launching. When we had an E-, F- or G-impulse motor, I had to remind many to back away to get the 30-foot clearance required as a minimum.

If you don't mind, I'll take down the other thread you started with the same post.

I was at a Cub Scout launch on November 9th. Can you believe an A3-4T engine CATOed. If you attempt a launch with an E12 there is a good chance it will CATO. Three out of the six I used CATOed.

Thanks for the clarification and I appreciate what LCO/RSO do for us all.
You can knock down the cross post
