For my Roo, I decided to go with the retracts from Top Gun (www.tgajets.com). They are supposed to be beefy ..... designed for turbine aircraft. I also ordered their knee-action struts. I am told that the knee-action in these struts will help reduce the bounce on landing that is common on Roo type aircraft. The gear and struts look great in the pictures ....... I ordered them last week and should get them any day now. I will let you all know ... at least how they look.... when I get them Bob
