I'm building an Big Daddy with my wife, and as usual, I enter everything into Rocksim to ensure things go well. I am seeing stability numbers that seem awfully low. Doing some research, I found that Rocksim seems to have issues with short and fat rockets. I saw discussions of using a base drag hack in Open Rocket to trick the program into providing more reliable numbers.
I have found some videos that talk about using them in Rocksim 8, but I'm not sure if those hacks are usable in Rocksim 10?
The only changes I have made from stock kit are to cut down the nosecone shoulder to 1.125, put an 1/8" plywood bulkhead and bolted in eyelet inside the nosecone, an 21" nylon parachute and 1/4" cotton elastic shockcord (with a short piece of kevlar inside the body tube).
