I 3D printed and tested an M6A3 bazooka rocket. One of the last ones I tested tumbled because of no weight in the nose. I added 6 grams of play dough and it flew perfectly. Its using an F15-0 estes motor!

This was another I tested but it only had 4.5 grams of play dough and went off course so I believe the minimum is 6 grams.

Does anyone know why it won't fire straight and how to fix it?

I 3D printed this rocket and I'm using a launch tube. The tube is like an inch or two in diameter bigger then the rocket. It's using a single E-Class 12-4 engine. I'm just looking for advice on why it isn't going straight and possibilities on how to fix it. Thank you!

Edit: I just tested another rocket and it was more successful then my wildest imaginings. I implemented some of the things mentioned here and added about 6 ounces of play dough to the nose cone, added a guide rod, upgraded from a G class to an F class, and found the CoM then did a function test before launch and it flew straight and true to about 1500 feet then started deviating until starting to descend at 2000 feet. Thank you to everyone for your help and advice!

My friend sent me pictures of this $20.00 USD bill he printed.

It's only one sided and has no serial numbers but it has watermarks, UV strip and, color shifting ink. What do I do in this situation? I went to his place later today and they felt like real cash too. Is it technically legal because its one sided? Do I call the secret service?
