I bought Quest bulk rockets and engines (A6-4)to use as a craft at a camp for Foster Children that our church puts on each summer. We have built model rockets with the boys each year for the past 6 years. I try to buy a different model each year to make it interesting for the boys and 2 summers ago I bought the Quest products. When we started building the rockets I was not happy with the design of the Quest rockets but thought...well I can live with it. When we launched the rockets, the Quest engines (made in China) had several failures. The flame would burn notches in the back of the engines (the hole at the back) and cause the rocket to fly off course or even spiral after take off. I had to apologize to the boys for buying bad rockets and tell them that next year I would return to Estes products, which I did this last summer. I will stick with Estes engines (made in the USA) from now on!
