Brief
The Estes Challenger II is another in the line of rockets that uses the fin can that originated with the Enerjet 1340 and is currently available molded in yellow as part of the Estes Eliminator. The Challenger II is a fairly versatile rocket that can be built to fly on motors from 18mm to 29mm depending on the size of your field. My field is B6-4 Field, and since they don't make a 29mm B engine, I went with the 18mm mount.
Components
- BT-56 body tube (18.0")
- BT-56 fin can (Estes Eliminator kit)
- PNC-56A nose cone (Estes Eliminator kit)
- 18mm engine mount (forgotten BT-55 Estes kit)
- 24" Kevlar shock cord
- 24" sewing elastic shock cord
- Medium snap swivels (2)
- 18" parachute
