Here's a question for the motor gurus out there:
On Quest and Estes engines, they give you the Motor Weight and Max Liftoff Weight. Now I know "Max Liftoff Weight" is just a suggestion, but it is an educated suggestion. My question is does the Max Liftoff Weight include the Motor Weight or not? For instance, on an Estes F15-4 (big to show a big difference), the Max Liftoff is 595 grams and the motor weighs 102 grams. Can my rocket weight be 595 or should it be kept under 493 grams (595 - 102)?
