Has there been anything said about a Ross drive when it is used in a pusher, 
there doesn't seem to be any chance of the thrust bearing that is in the front 
holding up for any length of time, I have one from a fellow over at Merrit 
Island, Fl. that he has been using on a 13b on a Cozy. He wanted me to install 
a better thrust bearing. The front seal  came out after 2 hours,

Several are used in pusher gyro's. Gary Buster, how is your Ross holding up?
