What would you consider as too much noseweight?

Don’t believe everything your sim tells you. I’ve always waited to add nose weight until I have the rocket built and configured for flight with the heaviest motor I plan to use. Then I’ll add the actual weight needed to get the right stability margin. Just recently a member here posted how he added nose weight according to the sim and found he had a much larger margin than needed. That extra weight means of course a bigger chute, more stress on recovery harness, etc.

Just something to consider.

+1 on waiting till build is complete. Both Or and RS indicated my L3 would need lots of weight, but some strategically placed laundry shelves... and no weight was needed.

Yeah I am going to wait until I have everything completed to add the weight and see where it brings the CG to.

Still debating rather or not to use a seperate parachute for nosecone or just connect it really well.

I don't see the mentioned in the thread so I thought I'd add this, since I've had it happen in a flight. Use a forged eye bolt or u-bolt on the bulkhead and a reinforced back plate (like a fender washer) behind the nut on the backside to spread the stress load on the bulkhead plate. I have had a standard press-formed eye bolt bend open to almost straight and cause a separation, as well as seeing several eye bolts pulled straight through a standard 1/4" bulkhead plate because of a heavy nose section and too short a shock cord. Allow plenty of length on the recovery harness as well as mentioned earlier. Good luck with your L2.
