I have 3 sets of gears, main and tail rotor, for my 450 SE. One set is white one set is light blue and the last set is dark blue, What is the difference in the gearing other than color??? I think the white were for original slow speed tail but I can't remember anymore....

The newer gears for the tail slow it down. The large main has not changed in tooth count, just the center hub for the one way.

The newer gears slow the tail down??? how would that help tail authority for 3D moves???? I figured they would speed the tail up for better authority

IIIRC it was because of then higher head speeds and exploding tail hubs. Count the small drive gear that's attached to the belt pulley. I bet the old one is smaller then the new one. Above 3200 headspeed my horrendous collective management can't get the tail blow on the newer gears.

I should clarify, the lower large gear and small tail drive gear are a different ratio to slow down the t/r rpm. Also the newer gears are supposed to be of different material. What long way the Trex has come
