I had to make my best guess at the dimensions of several of the Geo Sat LV parts namely:
Fin thickness (3/32"?)
Diameter of the wood dowels (1/16"?)
Dimensions of the booster standoffs (1/4" span? 10" Length? )
Dimensions of the launch lug standoffs (1/4" span?, 1" length? 45degree offset angle?)
Actual fin root length (2.03"?) and fin tip cord length (0.83"?)

Can anyone supply these details from an actual kit so I can create a better RockSim file and have a more accurate sized clone?

Based on the simulations in the attached file I would not want to fly this rocket on any of the B motors that are recommended. The C6-3 motor is barely adequate, simulation gives about 300' AGL and 22mph off the tip of the launch rod!


Bruce, I have an original kit at home. I can check the details tonight when I get home. This is one of those birds that needed 24mm power. I've been toying with the idea of converting mine.
