Hi all
I am new to this forum so please be gentle
I am working on my new rocket (v3 after v2,v1 both failed)
Some info:
Rocket body is cardboard tube
19.5" length
1.5" diameter
Fins: balsa wood
Engine:
Candy propellant 3 part (home made)
each part is 1.5" diameter about 3" height
total engine length is like 8" to 9"
I molded the propellant into same cardboard tube in a way It can exactly fit the rocket body tube.
Sorry for the mass of questions,
what is my engine size? Is it ok for this rocket size?
Why do I need to make core hole in my motor?
Is it possible to drill small hole in the engine and insert small birthday sparkler without the core hole?
What is a recommended material to build the nozzle? (epoxy, gypsum cement?)
What is a recommended material to cover the motor top part in the rocket body?
Thank you very much!
Sharon
