Hey guys, did my bearing upgrade on the main shaft and tail. Awesome! and smooth as silk. I went with the slightly thicker TRex 600 ABEC 3 bearings and had to dremel down the metal portion(bottom) of the main gear hub, as they are 4MM thick, however they fit right in the same holes fine. I had a good ABEC 1, 3MM (closed face) bearing from a King and put that in the middle bearing spot and used the ABEC 3s on the top and bottom. I put the ceramic bearings in the tail. I will eventually upgrade all the bearings as it provides very smooth operation. The CNC washout has superior bearings then the plastic one I found out after I pulled my plastic one. I knew nothing about bearings until I did a little research and found the higher the ABEC number, the tighter the tolerence and smoother the bearing. Heli Direct has ABEC 3s and Ceramics(best) just check your Belt manual for the correct size bearings.
