No, not even parts. They have not been made in years.
No, hardly anything is as reliable as a 302; esp alcohol fueled motors
No to current motors (Konigs have not been made in a long time)
About 45 ft lbs of torque, 90 hp @ 10,000 ... current GRP (Rossi) motors are getting close to double the power

They are made in Italy. I do not know if they have a sales agent in Australia.

Rossi isn't a member here but he is on Hydroracer: http://www.hydroracer.net/forums/member.php?u=18
