Hello everybody. I am somewhat of a novice in the rocket world. What is the largest engine I can put in the Mirage rocket. In the past, I have had a tendency to over spray paint adding excess weight. With a rocket of this size I can see that it might be a problem. I see Aerotech is recommending G80 7-T. I was just curious if there is anything bigger. Also, I do not have any certifications. Any suggestions would be greatly appreciated. Thanks.
