Eachine E160 RC Helicopter Spare Parts Bearing Set
A part of the review has been auto-translated.
Product as described. Good to have it as a spare.
All good!
Although these bearings come with the Eachine brand, they are about 1mm thicker than the bearings that come with the heli. As a result, when fitting them into the bearings, a total of 2mm is left over, which affects the position of the ring that holds and fixes the main shaft in the recess in the shaft, suitable for fixing the ring bolt. Thus, on back flights (belly up) the ring can move, disengaging the main gear from the engine pinion.
One of these bearings is in contact with the main gear, and here we have a small error in the design or execution of the E160's parts. When fitting the main gear to the propeller shaft, the shaft hole should exactly coincide with the main gear hole where the screw that secures it to the shaft is placed. But this does not happen, and in order to insert the screw, it is necessary to apply a lot of force, because it enters at an angle, excessively forcing the main gear against the central ring of the bearing, which works very hard and is damaged in a relatively short time. I think I solved this problem by replacing the screw with a sewing pin.
Okay.
good
