Re: Open Rocket

Not quite sure what you've done there. Open rocket is a single .jar (java) file. You simply place it somewhere and open it, of course you must have java installed on you computer.

It's official home is here

Re: No Big Deal

Nice fins Nic, your going to need a simulator to tell you how hot it gets then a blast furnace to test it in.

Re: The Eggtimer

Me either.. :lol: The wires are blue in colour, and are quite long. There's absolutely nothing written on the box. I got them from a pyro friend in Townsville. He said they have a low no-fire/all-fire current, and are continuity test safe. But then, that's why we ground test. :D (That's another rea...

Re: No Big Deal

Would you still need a join somewhere so you could slide it onto the motor and tighten it up? I reckon you could just use a friction fit, in the same way as you would with the composite fin can. I assume Nic plans to use the ring on the back to hold everything together. If this was used in Rocket S...

Re: Wildman Jr Build - Look out HPR here I come

New scales arrived today so I was able to get a final weight for the lower body section so have been updating my Rocksim model. I refined my calculations for how much additional weight is carried due to using a 3 grain motor case with adapters and corrected the missing parachute protector. The end r...

Re: The Eggtimer

Did you get the Rev C or D boards? Mine are Rev C. Apparently the main differences are the D version can be modified to take a 9V battery to power the alt, and the hole spacing has been standardised so the builder can add terminals. I -think- there was also some mention of a jumper so you can easil...
