Good--thank you for reporting their ejection charge mass reduction. The original Quest also had motor problems, which to their credit they quickly corrected. My first Quest motor, an A6-4 (black powder, of course) flown in a Quest Pipsqueak, fired its ejection charge as soon as the propellant burned out, at top speed, which resulted in a Kevlar cord "zipper" of its body tube. The motor either lacked a delay charge, or a void along the side of the grain (or maybe a crack) allowed the flame front to instantly rush forward and ignite the ejection charge. I contacted them and submitted a MESS form, and they replaced my motor pack (and also the kit, if memory serves). I used many Quest motors after that, and never had another one fail.
