Brief introduction:  it is a upgrade spare parts for T-rex 450SE, it can improve flying performance and let customer feel delight for flying. We use full size, bigger thrust bearings to eliminate its internal step design, so the force to the main shaft can largely be absorbed by thrust bearings on the block..

Features: 1，we add trust bearings on the base of original 450 bearing block to adsorb the force largely on main shaft, it can reduce friction and longer use life of bearings, and eliminate vacancy seat from the direction on shaft.

2, internal step design of no thrust and high performance and larger diameter thrust bearings can effectively increase the bearings’ service life.

Including: bearing block*2  ball bearings*2  thrust*2sets

Weight of parts: bearing block 4g, ball bearing 1.8g, thrust bearing1.9g. (all：15.4g)

Mounting and use：

1、The product is used to be as a replacement for metal main bearings block on T-rex450SE and those similar helicopters or work with the high precision fiberglass 450Se Frame.

2、please assemble the product according to the diagram below step by step.

Notice:

1、 Thrust bearings include bearing and two pieces of backing rings, the backing ring with bigger diameter should be put under the bearing block.

2、Please add some lubricator while assembling or while using to insure its good working performance.
