Electron Beam Model Rocket Launch Controller

I have used this product launching at least 100 rockets now with a group of Cub Scouts in my Den and have not had issues with launches. As another person wrote, the safety button was tough to hold down for a young person, but after about 15 uses it seemed to soften the rubber on the safety pin and it worked fine for ages 8-13 yrs.

I have two of these in my field box and they have never failed me. Great for a lpr rockets!

I have and electron beam launcher. It does work, but not well. I wanted my 5 yo son to launch the rockets maiden voyage, but the safety key is too hard to push down for him so i had to hold it down. The launch button for whatever reason took at least 20 seconds to ignite even an a-series motor and he thought he was doing something wrong.
