2 Stage Sugar Rocket - Category 5 Hurricane

A two-stage rocket derived from the 'Hurricane' is currently being designed. This rocket, called the 'Category 5', features two I-350 motors that should propel the rocket well over 7500 ft. Clearance will be sought from the CAA before this is launched.

Here is the current design.

You may be wondering why 2 similar motors are being used instead of the traditional big booster -> smaller sustainer setup. The reason lies in the fact that the biggest motor this tube can take is an I-350 sugar PVC and based on simulation in Open Rocket the motor seems to be strong enough to lift the extra weight of the upper stage with ease.

Material / Components List (so far) - sans motors

• 1 and 1/2 blueprint tube or a full length fabric tube
• 2 small umbrellas 
• 1 large umbrella
• 2x 1^.25 PVC end caps for bulkhead and ejection plunger
• Nosecone made from body filler
• 1.5 inch PVC drain pipe for couplers and nosecone neck
• Solitex or MDF wood based Clipboard  - for fins
• Screws? I forgot the size they are but I know i need 8 1/8 Self tapping screws
• 2x 1/4 inch machine screw for launch guides - the head of these are big enough to function as buttons
