How about a B1-7 motor?
How about a B1-7 motor? In 1997, Stuart Lodge set an altitude record that still stands. At the 1st World Air Games, held at Ankara-Golbasi in Turkey, he flew a small FAI S6A Class (single-stage streamer-recovery) model to an altitude of 1,850' (569 m) on a Delta B1-7. These Czech motors are 10.5 mm in diameter. You can see some Delta motors and other foreign-made model rocket motors here: http://homepage.mac.com/georgegassa.../Engines-F.html
