This was flown with an Ellis Mountain E12-10. 

Left t' pad much faster that I thought! I was still thinkin' Estes E12. Begad! Fantastic straight flight. Ya scallywag! Estimate from ROCKSIM was 2200' I believe I got just about that. Ya scallywag! 2K for sure. I did nay use an altimeter because t' be honest, its an old motor and I had no idea if t' ejection charge would be effective. Avast, me proud beauty! There was a bit o' wind so I had t' go an 1/2 a mile t' recover it. Well, blow me down! Fun!
