Where can I find RockSim files for your rockets?

Most of our kits have RockSim files and can be found in the description of the kit on our website.  If you don't find one, email us, we may have one that is close you can use.  Important: please keep in mind that most of our RockSim files may not exactly represent our kits - please verify the lengths and weights match what you are building before using the sim file.

How big a motor can I put in my cardboard kit?

Cardboard kits are really limited by airspeed, not motor size.  When you sim your rocket, check the maximum airspeed.  A good rule of thumb is; cardboard kits can usually fly up to Mach 0.85 before they have structural failure.  Of course this depends on how you build it and other environmental factors like wind shear, etc.  If you are in doubt, you can wrap the airframe in 1 or 2 layers of fiberglass.

Can I certify Level 1 with my 2.6" Carboard Kit?

It really depends on airspeed - see the FAQ about "how big a motor can I put in my cardboard kit".  Most 29mm Level 1 motors will be fine in a 2.6" cardboard kit.  It is a good idea to sim your rocket to make sure you are not exceeding Mach 0.85.

What is Thin-Wall Fiberglass?

Fiberglass tubes usually have a wall thickness of 0.063 for sizes 4" diameter and smaller.  Thin-Wall fiberglass tubes have a wall thickness of 0.040 which makes them significantly lighter.  Our 38mm and 2.6" fiberglass kits are all thin-wall fiberglass.
