description
Of the 4 motors in the package, two appeared to burned completely, all at once. One appeared to blow the ejection charge with no delay. The fourth burned all at once, with no ejection delay. I have written directly to Estes describing this and with a photo and heard no response yet.
Comments
Failures were almost immediate, as soon as launched. All four motors had the same serial number/date code. I still have three of the four, in burned out condition.
