Nose cones can be hard to come by unless you make your own or buy commercial sizes. I've seen conical firework rocket headers offered but nothing in 50mm. It's always nice to have a stock of sandardised parts for a project. Everything gets recovered, it just saves time and effort sourcing parts and allows more flight time.

Hi everyone. I want to get a comparison between cat.3 firework rocket engines and the type available to model rocketeers. The biggest non licence engine in the UK from Estes is D12. We are not allowed the E size. We can however single or stage 2 or mayde 3 D's but it gets expensive. I've posted the Estes engine chart below. If the firework engines have more power and where available without the rest of the firework they could be used in model rockets.

Better still would be making my own. Being allowed to mix 100 grams of rocket propellant would give me 2 or 3 good engines and would add another aspect to the hobby. I'd love to be able make my own engines, I resist the urge because it's illigal and I fear the consequences of being caught in these paranoid times.  It's a shame because it's not all about going higher or faster but testing new ideas, slightly bigger engines could lift more onboard equipment and different nozzle configurations could be developed.

If anyone knows anything about the bigger firework engines or has any ideas heres the chart.

Thanks.
