Thanks, Warren – I’ll proceed with the plan as drafted.

Adding to Ken’s and Bear’s responses,,,, another way to think about CP – center of aerodynamic pressure – that is the pressure exerted on the external geometry of your rocket as it travels through the air. So the only way…   Read more»

Mike – I have also used PML multiple times, and even ordered a set of custom fins from them last January and agree with Dave – a quality operation. I dealt directly with Kim Uroda, their sales manager @ 810-327-1710….   Read more»
