countra rotating propellers

Looking for any designs for contra rotating propellers to use on several design ideas that I have. I need to keep the weight down but overcome torque problems.

I am not sure what you are asking but: www.toddsmodels.com is the only source I know of for counter rotating props (10x4.5).

Well, I guess the Vario prop system can be used to produce contra-rotating props, but those will be heavier and more complex and more expensive than ready-mades. - see: www.aircraft-world.com
