I fairly new to model rockets and brand new to Rocksim. Grandkids got me into model rockets over Christmas. Now Im
(sigh) hooked.
Im working on my first modification project. I have two Estes Super Neon XL kits and Im mixing the parts. The stock Neon uses an 18 inch BT-60 tube and an 11.25 inch BT-60 tube. Im combining the longer 18 inch BT-60 tubes from each kit to make one Super Neon with a 29mm motor mount (from Apogee). Im combining the two smaller 11.25 inch tubes from the kits with the stock 24mm motor to make a Not-quite-as-Super Neon.
When I opened the kits, I weighed all the parts. Then I built the rockets in rocksim. I noticed most of the calculated weights for the parts in rocksim were different from the weights I obtained. For example, the 11.25 inch BT-60 tube in rocksim comes in at .9249 oz. The tube I weighed came in at .582 oz. Should I over ride all the rocksim weights, or use the rocksim values. I'm concerned where my CG will "actually" end up. Or am I doing something wrong (the most likely choice)? Thanks.
