What size model rocket engine should i use for ...?

Question

... a wizard rocket. I know that I shoul use estes, but it's a science experiment. I need this information for Aerotech, and Quest Aerospace. Thanks

Answer 1

I would use the smallest size for its first flight which would be an A8-3 according to the attached specs.

Answer 2

I'm thinking PVC sounds like it may be a bit heavy for a model rocket. However, besides wrapping the engine in tape for a friction fit, you can also have the engine extend about 1/4" from the end of the body and wrap a layer of masking tape around the engine and body. The primary aim of building a model rocket is light weight. The lighter it is, the better it will fly. You also need to make sure the model rocket is stable before launching it.

Dear Scientist WES:

You know these aerospace people--they're extremely competitive. Be bold, pack a punch for the economy too! Request an order with both companies; run an efficiency analysis--you'll steal the show. By the way, what was your decision for the 1/4 mile radio telemetry design?

P.S. Don't listen to that Mark G; he's working on a coarse-air project.

Answer 4

ahhh, how high do you want the rocket to go, how much does the rocket weigh???


kinda important to answer the question.

Answer 5

I've always gone to Estes with the idea of putting the largest engine in the rocket that will fit. Bigger diameter had more power. Unless you are working with a multiple stage rocket where the delays between stages are critical, the bigger the better was always my plan. I'm sure these days there's a web with the lifting capabilities for each size, and you could put your prototype on the scale at the PO and select an appropriate engine (or engines).
