I have a rather stubby 3" rocket with some heavy duty fins. I plan to launch with a range of motors . . . from a G70 to a J350. I am worried that the CG is about right for the G70, but will be too far AFT for the J350.
I came up with a solution using a system of interchangeable weights added to the nosecone depending on the flight configuration. Using 3 oz. weights, I cut one in half and left two whole. Using 1/4" screws I can now add either 3 oz. or 6 oz. (or nothing) depending on the need. I have not worked out the exact requirements in RockSim yet -- so I can use different weights if necessary.
Thoughts? Does anybody see any fatal flaws with this solution?
Thanks.
