Big as you can get them!! :twisted:

Actually, I think Blake was talking about limiting it to L2 motors so that more people could compete. I'm hoping he does a "First-to-10,000 feet" competition as well, as it is quite a serious test of your design skills - Any diameter & any motor, first to 10,000 means you have to really sharpen your pencil...

Nic hit the nail on the head! It will be L2 range of motors, so flyers will have completed more stringent certification processes, however not too limiting for those are not yet L3.

There is plan of a real challenge such as the fastest to 10,000'. This will not matter who gets off the pad fastest, rather who has the skill to hit the finish line the quickest.

Is there actually official rules for a drag race or is it just generally known?

No real rules, it is just something for fun... Everyone is a winner in those events ;-) then again, we may come up with some goal for everyone to aim for

Looks like Crazy Jim already answered this on the us forums

Oh heck ya....cheating is not only acceptable, but highly encouraged.[I love nuclear igniters!]

I never make the rules till large amounts of alcohol have been consumed just prior to launch day......even then they can change during flight.LOL:lol:..........

...........but since this will be on foreign soil & ya'll have the home field advantage, exceptions can be made. We'll get an early start:

Rule 1. All entrants must be rum/bundy drinking & speak Pirate....Arrrg.....ye bilge water drink'n mate's.

I can just see this. Aussie accents speak'n pirate down at the Rocks!

Kevin.... Blake already made me eat/wear Vegemite. Actually it ain't that bad when done right, but it doesn't work to well as eyeliner!


Ok it that sort of race. Good to know

Watch out for Aussie launch rails with built in rabbit traps.
These state of the art "traps" with built in computer chips can detect a kiwi rocket as soon as it comes anywhere near a launch pad.
Remember: the rules are - there are no rules. All's fair in love - and winning the drag race.

No need for a rabbit trap. Only need Velcro. Kiwi rockets are all woolly aren't they?

Well, if the Kiwi rockets are all woolly, then you don't even need rail buttons! Just a couple of wheels on the launch rail with a loop of the hooked side of velcro running thru them. Walk up, stick the rocket to the velcro strip and you are ready to launch! as the rocket moves up the rail you will also get a nice RRRIIIPPIIINNGGG sound as it peels off!

Can't wait to see someone try this!

Sounds like the calling of a drag buster nic named the singed minge, and although the velco is a great novel approach (and Kiwis don't mind inovation) Id prefer a quicker exit off the rail rather than hosing off the rogue aussie trying to shag it since a few days out in the heat drinking warm piss (VB) can confuse those buggas into chasing our females and since they cant tell the difference between a hot Kiwi girl and a sheep let alone a woolly rocket, Im taking my chances :)

Thinking of a rocket called Marmite now :)

OK,

To summarize, up to and including a L2 cat motor, and a drag race pure and simple?
