    high quality control, low quantity control

    All products seem to be of very high quality and are consistently reliable and functional. What has been lacking at Estes in recent years is quantity control. There seem to be a high number of products at any given time that are out of stock. Foreign production reliance has therefore become an annoying problem for consumers and the company in this area.

    Love it! Already used one tube to buid a stand-in replacement for the upper stage of my Hobby Lobby Epic II. since it is NOT an exact copy, I call it the Quepic (Quazi-Epic) II. Unleash the creativity!
