This was flown with an Ellis Mountain E12-10. 

Left the pad much faster that I thought! I was still thinking Estes E12. Fantastic straight flight. Estimate from ROCKSIM was 2200' I believe I got just about that. 2K for sure. I did not use an altimeter because to be honest, its an old motor and I had no idea if the ejection charge would be effective. There was a bit of wind so I had to go an 1/2 a mile to recover it. Fun!
