Hey..In that thread(see above link) there is a guy who is a Kyosho Dealer...PatternFlyer is his screen name and apparently he has P & A Hobbies...You could email him at: [email protected] last time I checked which was a few months ago he had several gas versions in stock...Not sure of availability as of today??

The other option I knew of would be Kyosho of America:
http://www.kyoshoamerica.com/

I'm finding the kits gonna run $239(US) for the gas version...The Electric version is more expensive from what I've seen...

I'm not sure about shipping to Australia??

Hope you find one...

Have Fun...

Chuck
