I cant think of much I have to *donate* towards such an effort, but I could *loan* a "Team Australia", my US-Ground-Freq-Legal 75Mhz 7C PCM Radio, Battery packs (12v packs - CP2400's x4 and RC3300 x 6) and a rack of 5 Tritons - for the duration of the trip that is.
12v Power for the Tritons would have to be supplied though, as my 20amp supply is a Linear one and wouldnt handle US power.
Given thats over $2K worth of gear, Travel insurance would be nice to see though.
And of course, if you dont know how to program a Futaba 7C radio, then I offer my services as driver
However it occurs to me, that I dont know that I'll be able to stump up the airfare, and seeing as how Glen has said he will, and his Spektrum is just as legal in the states, maybe it would be better .
The batteries and charger offer stands though. We all know what the *expensive* parts of most Robot's are. Radio, Esc, Batteries, Chargers, so that should help. _________________ Great minds discuss ideas. Average minds discuss events. Small minds discuss people

Pop updated, thanks all!
Can I presume to put Glen, Jake, Angus, etc down for CAD work?
A thought about the weight: If we build a non-kinetic lightweight, we can fight it back in Australia. If we build anything bigger or kinetic, then its a one use disposable bot as far as Australian comps are concerned. I'm not against a larger bot as such; if it is half way competitive, we can leave it in the states with as many parts as possible and sell it off on the RFL forum. That also saves us the return frieght BTW, which will be expensive for something that size.
Before you go designing your dream combat bot, take Judge Dave's advice on these two points: "Don't bother bringing an untested design" and "Study the opposition". Let's look at the top five bots in the light & middleweight classes and figure out how we would beat them, then come up with a design that can be tested safely. _________________ Australian 2015 Featherweight champion

i suggest the wiki as the repository for this bot.
talk about it here but when you change the wiki put a link in to the wiki page.
I'll do software etc, if its legal we can run my radio system, i may go to bluetooth or zigbee (which are legal world wide, but i dont know about RW).
I'll help with welding etc, we have enough space here to store the thing.
what styles are we looking at then.
Spinner - ruled out
flipper
Plan-C style spike
rammer
lifter
crusher
any others?
I don't know how well Plan-C will scale up in terms of height. The shaft in the featherweight is 50mm off the bottom of the bot (excluding armor and clearance) so thats like 60-65 mm and thats already just going to clip cobra.
so scaling that up to a LW would make that say 80 mm.
The power behind it would be truly scary. I am thinking 25mm Ti or SS shaft minimim. Tool steel tip, ~4kg worth of Co2 for lotsa shots.
lol we are talking small cannon here not "big game", Big upside is minimal drive requirements. Needs 2 way radio.
Plan-C style valve works for the flipper (launcher ;->)
Rammer... could be intersting but still... ;-> magnet wheels are a must. I think i have worked out a way we can make them with just flat NiBs and still avoid coging and up the stick force. A123 cells all the way ;-> This becomes more viable if we can get laser guidance running. I may have worked out a way of doing this digitally with just a PIC, photodiode and an amp.
Crusher.
mmm fun ;-> glen we need that actuator ;->
actually i was thinking combined Co2/air pump and hydraulics.
Co2/air for a "snap" closed and hydraulic for the crushing.
weight isnt nice for this though, lotsa bits, and lots of them are heavy, needs lotsa batteries too to power the pump.
lifter.... cmon ;-P _________________ Mechanical engineers build weapons, civil engineers build targets
