I got this rocket from a friend, so I didn't actually build it, but the construction looked like it wasn't a very good design, as the inner BT is so small that packing the streamer becomes very difficult, and the outer bt is so heavy it keeps the rocket very low. I have had this rocket lawn dart at least twice before I officially decommissioned it. tho only good thing is that the plastic is strong enough that even after a catastrophic crash the rocket can be easily snapped back together, and at such a low cost it can almost be disposable.

This is a GREAT rocket for launching in a large backyard. Recommend using a parachute recovery for this rocket to make the journey last longer. Nice rocket for younger kids. This easy to assemble rocket is fun to launch on 1/2A3-4T model rocket engines.

We've used these in our summer camp for the older campers and they are alot of fun to both build and fire off. great activity.
