Well I got my Sceadu for $199 and its all bearings. 2 on the main shaft and 2 on the tail driveshaft. It also has bearings in all the moving arms. It can be upgraded to a 50 for a few bux and no major changes. I set the heli up in 1 weekend according to the manual and she lifted right off and was real stable. I also like the removable weights in the paddles.
