Tailcones and Boattails

"Tailcones greatly reduce drag induced by base turbulance. Boattails do the same but with a 'retro' style."

Tailcones
Urethane Tailcones:
PML carries an entire line of Tailcones for reducing base drag on high performance rockets. All our tail cones are cast in one piece from light weight urethane. They can also be used as a "pass through" reducer for airframes. Each tailcone is 1.75" long with a 0.25" shoulder on the large diameter; there is no shoulder on the small diameter.
HAMR Motor Retainers are perfectly suited to work with our tailcones.

Boattails are long, ogive shaped components that are attached to the tail end of the rocket and serve to reduce drag (and can add a "retro look" to the rocket). These boattails are made by modifying our existing line of nosecones. 2.1" through 3.9" boattails are made of plastic while our 6.0" and 7.5" boatails are fiberglass. Centering rings are included.

Plastic Boattails:
On plastic boattails, the tip is cut off at the point that will allow the motor mount tube to fit through the opening.
