Where To Buy Materials

 

Since we are often asked where to buy various components or materials, here is a list of some of the commercial items we use on our rockets or would recommend.
We do not have affiliations with the listed providers.
 



 

Item Supplier Description
Altimeters
Jolly Logic
https://www.jollylogic.com/
A great range of altimeters that are very easy to use. We use both the AltimeterOne and AltimeterThree.
HidroMax Launcher
Air Venture Sdn Bhd
http://www.hidromaxrocket.com/
and
http://www.hidromax.com/
A great new versatile water rocket launcher and parachute deployment mechanism.

See here for more details

 

Tornado Tubes
CoolThings Australia
http://www.coolthings.com.au
We use these tornado tubes to join spliced bottles neck-to-neck when assembling longer rockets.

Single tube:
http://www.coolthings.com.au/vortex-valve-tornado-tube.html

CoolThings offers a great deal when you buy a box of 24:

uMAD Whooshtronics
http://www.whooshtronics.com
uMAD:
http://www.whooshtronics.com/products-t110/umad.aspx

The uMAD is a magnetic apogee detector used for sensing when the rocket tips over at apogee. It was developed for pyro rockets, but can be used with water rockets as well.

PVC Launcher
Water Rocket Pop!
http://www.waterrocketpop.com
Mike Passerotti's PVC launcher with several add on options: http://www.waterrocketpop.com/orders.htm

Used for launching rockets with a full bore nozzle.

Sikaflex 11FC
Bunnings
http://www.bunnings.com.au/
This glue is a flexible polyurethane glue that sticks fairly well to PET. We use it to seal bottles when splicing. It's also suitable for attaching fins and other components to the rocket.
Electronic Components Digikey
http://www.digikey.com/
We source most of our electronics from Digikey. They have a huge range to choose from.
LiPo Batteries
Hobby King
http://www.hobbyking.com
70mA LiPo battery:
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=7566

We use these batteries with some of our flight computers. They have a great capacity and weigh around 2grams.

RC Servos
E-Bay
http://www.ebay.com/
E-bay has the best bargains for RC-Servo motors. They are best bought in packs of 6x or more as you will want to have a few spare when your rockets don't do as they are told.

Search for "RC micro servo" and then search for the one you want. We mostly use the 9 gram versions.
