Christchurch, Low Power Rocketry Supplies
International Rocketry Suppliers
Australian Rocketry has hundreds of high and low power items and has in the past been a supplier to New Zealand for Cesaroni Technology (CTI) high power motors. We do not recommend purchasing from Australian Rocketry at this time due to delivery issues.
Low and High Power International Rocket Manufacturers
Shipping costs to New Zealand from USA and Europe are high. If the shipping costs look low they may be USA only and you will be contacted by the supplier to choose international shipping options. If the total purchase price plus freight converted to New Zealand dollars exceeds $ 400 then when your parts arrives in New Zealand you will pay GST + Customs inspection and agricultural fee. If you are buying from large manufacturers such as Public Missiles we recommend checking with Aerospace Education or Australian Rocketry as you can purchase through them at a reduced freight cost. Buying a PML 1/4 Patriot locally for example will save you up around $ 40.
High Power Rocket Kitsets are not what you would expect if you are used to building models or kitset furniture. Often they only come with the basic airframe and you have to purchase many other items to fly them. Often they come with no instructions at all. This is to keep the price down for people who already have the other parts.
Public Missiles (USA)
Public Missiles Ltd (PML) build over sixty quality kits with good instructions and many accessories such as shock cords and launch logs. All models are high power starting with F sized motors. PML have excellent instructions and lists of other items required for your build which you can view on their site. Sizes vary from 63mm (2.5") diameter rockets up to multi-stage 152mm (6") Rockets. www.publicmissiles.com
The Public Missiles 1/4 Patriot is so popular in New Zealand it has it's own Facebook page.

Apogee offers a huge range of model rockets and components from low power to high power. They also offer a huge range of 'how to' videos and newsletters. Shipping can be expensive so it pays to check if you can share shipping costs with another member.
Epoxy Resins, Carbon Fibre and Fibreglass
You can buy 30 minute epoxy in 250gram packs costs about $ 27 from a number of suppliers including Aerospace education here but for many jobs 30min is too fast. Slow setting epoxy is thinner and penetrates better and is ultimately stronger than 30min. You can paint it on to strengthen plywood parts and inject it into fincans. One litre of slow setting epoxy is 1/3 to 1/4 of the price of the small packs. You can thinken slow setting epoxy to make perfect fillets using need colloidal silica. To strengthen fillets you can add chopped fibreglass. You can speed up epoxy by warming it which is effectively what the additives do in 30 minute epoxy.
Many NZRA members rely on rocketman parachutes to bring their rocket back safely. Their standard parachute is the strongest and most reliable standard parachute on the market due to it's tough tangle free design. Over 100,000 parachutes sold and great value. If you are short of space and need to minimise weight then they also sell Ultra Light Annular parachutes which require careful packing and deployment.
Rocketman parachutes deploy gently with the minimum possibility of tangling due to their 4 leg design with heavy duty lines. Watch this 15ft Rocketman chute deploy on a 25kg Frenzy Massive full screen with the youtube setting at .25 playback speed to see the deployment in extra slow motion. The chute was wrapped up tight in a large chute protector that lets the chute spring out as soon as it reaches the end of the payload bay. Based on this video I am going to make my nosecone to payload bay shock cord 3 meters longer so that the payload bay has more time to move out of the way before the main opens.

Is 3d Printing For You ?
Using a 3d printing plastic parts is unlike other modern devices where you follow the manual and it works every time. These machines squeeze hot plastic out of a tiny nozzle where tolerances of a few microns can make the difference between success and failure. Belt tension and frame rigidity are tricky to get right and and variables like fan speed, frame rigidity build surface and software parameters often need to be adjusted for different filaments. There is a lot of help online but at least half of the advice is contradictory or wrong. It's a great skill to learn but don't under estimate the time it will take to master. This troubleshooting guide gives you an idea of the issues you will learn to overcome. https://www.simplify3d.com/support/print-quality-troubleshooting/
Prusa MK3 I3
Prusa MK3 I3 is a well supported and reliable printer kit for under NZ$2,000. They are good for years of hobby printing without upgrades. The combination of Prusa filaments, Prusa Slicer and Prusa MK3 printer will get you up and running reliably. The headline features are direct drive hot end, auto bed leveling, heated bed and magnetic PIE spring plate. The reliability is achieved by Prusa running 500+ printers identical to the ones they sell 24/7 in a print farm. All changes to the setup and components are tested in the print farm before going out to customers. Initially $ 1,900 seems high but if you price all of the components, freight and time you need to upgrade a cheaper printer then it's a good long term investment.
I purchased my Prusa MK3 as a kit from RC Hobbies because I wanted the printer next day delivery and they have been helpful with advice, filaments, nozzles etc. This was my first 3d printer and I took my time with the build taking 9 hours to complete it in two sessions. The instructions were in an excellent colour manual as well as online so you can zoom into photos and read others comments from the build. You can also buy the printer direct from Prusa but check the shipping time, costs, time, exchange rate, GST and customs before buying.
I am happy to provide advice and help to any NZRA member with a Prusa MK3 printer.
