This is a two stage rocket. As you can see in the picture besides the paint they look a little different.
The one on the left is the first one we built, but unfortunately it got damaged before it even got out of the house and the payload section at the top of the rocket was shortened quite a bit.
No problem though, we just built another one which is on the right in the picture.
Luckily both fly fine even though one has been altered some. Two stage flights on 18mm motors. This is probably our most flown multi staged rocket and it's always flown really well.
Built 1-23-02 and 5-7-02
Diameter 1.33", Length is 29", and Weight is 3.6 oz. Parachute recovery.
