Quality product

Rocket engines did not disappoint. Every single engine ignited on countdown.

Products are good, web site overwhelming

I used the site to replenish an existing “kit” that lost its rocket and chute in a tree (big surprise, not!) It was not easy to get the correct engines and rocket and wadding. I ordered two of everything, and the order arrived perfectly packed so I should be good to go.
