The launch system is 100%. But, I need a “degrade kit” smaller rod, launch plate deflector, and central hub for the bulk of my son’s rockets. He is a teacher at a school that teaches severely autistic children up to age 18 or 21.
I had gotten this for him and didn’t know the rods were different.

How tall is it? That’s what I want to know before I order it cause I don’t know if it’s tall enough for my rocket.

This is a great launch pad....as others have mentioned....it's nice to add some 1 1/4" end caps.....then I thought....why not buy some 1 1/4" straight pipe attached 45-degree angle couplers to raise the launch pad to waist height (or any height) rather than having to bend over to set up the rocket. Then I added the end caps to the bottom.....minimal expense. To take it even futher....you can add gravel, sand or cement in the straight sections of pipe for stability. It's not rocket science.... or is it!
