I have a Maecow DX3 2.6" that I built a while back. During the building process I made two upper sections. One as the instructions indicated for single deploy with a payload bay and the other as a dual deploy with payload bay and electronics bay. I have flown it as single deploy in both configurations and it flew well. I now want to do a dual deploy flight but have a question or two.
During previous flights I used nylon screws as sheer pins but they are tearing up the tubes. Even with a grand amount of CA soaked into the tubes so I want to use friction fit with tape. How tight should the payload/nose cone interface be to overcome any force that it may encounter from the apogee charge?
This rocket is not huge and I have read elsewhere on the forum that many would suggest drogue-less. Thoughts from anyone? I was thinking if I just left my 9x9 nomex on that would be enough.
I am headed out tonight to test some ejection charges. Kind of want to get an idea of how tight the cone should be.
Here's a couple of pictures of the rocket. Dimensions are as follows;
2.6" diameter, 47.625" length. 23.875" Booster, 5" coupler length, 10.5" payload section and stock nose cone.
