I just installed the Robart 1/4 scale main gear on my Hanger 9 super cub.

The gear seems to be too stiff. Do I need to flex the O-rings to make the system more flexible? I installed all 8 O-rings on the unit.

It is so stiff right now that I can not see how it is going to take much shock out of the landings.

Thank you in advance for your help. Todd
