A10-3T Model Rocket Engines (4)

Mounted in a 1.3 ounce, 10-inch long BT-5 rocket like the FIRESTEAK this motor shot it up clean out of sight. Just for the heck of it, I even tried one with an adapter in the 3.2 ounce, 35-inch long, BT-55 AMAZON rocket... thinking it would barely get it off the pad -- and damned if it didn't lift that beast 12 feet into the air. Great for small and even medium sized birds, but with one caveat: The ejection charge is a little weak for body tubes wider that a BT-20, particularly if more than 15 to 20 inches long. In the case of my test with the AMAZON it did not have enough ejection power after traveling up the 30 inches up to the nose cone to pop the chute.
