Hey Mack, Both blades are 3g type blades. The 600e is the newer version. We do not use flaybarless blades and really can't feelmuch difference.The FBL are tip heavy but use what you have. I use Edge and Align 600d or what ever I get a sale on. Yep I still have the Scheadu. I think I would go for OS Hypers over TT motors. Never a problem.
See Ya,
Jim
