This is more of a general question. I've built a LOC Cyclotron for my up coming level 1 attempt. This is the biggest rocket I've built to date and my first foray into the world of 38mm.
Thinking about future possibilities... (in other words, I still have some money left in my wallet)... I was playing around with rocksim to see what a J motor would do in this rocket. Then I looked at modifying the rocket (after a successful L1 flight). I can add another 8-12+ inches to the main body tube to move the center of gravity forward to allow for bigger motors. If you just extend the body tube, the CG should move forward faster than the CP I assume.
Questions: In general, why would you make the body tube of a rocket kit longer? What is the motivation, advantage, or disadvantage?
Is it better to make the body tube longer or just add weight to the nose cone to migrate CG forward?
Any advice and/or experience appreciated.
