HI all! I have another question for you! Reading AFN book I read some different contrasting things about rockets. On AFN II it is said that the nozzle is 1/4''(~ 1/3 I.D) with 5.5'' spindle lenght for 1 pound rocket. On AFN III it is said that the nozzle is 45-50%(~1/2 I.D) of tube for a generic rocket, which spindle lenght is 78% of motor. On website posted by sjeef1 it is said that nozzle is 1/3 I.D. Using http://www.flashnet.dk/rts/ the nozzle is 50% I.D.. So can someone tell me to make ''perfect'' rocket what is the best tooling design ? Using larger nozzle I should use hotter fuel right? or to reach highest height is better smaller nozzle with colder fuel or bigger nozzle with hotter fuel? Is reliable using(http://www.flashnet.dk/rts/) software? thanks to all. My tooling have this design:
I.D 2cm
spindle lenght 15,4 cm
spindle width 1cm
