Hello all

so these motors are awesome . They cost 6.5 dollars and if prepared right they are really reliable .

In this article I'm going to go threw the motor preparation steps .

there are not only suggestions but a requirements for reliability with these motors .

first you will need to strip them down .

 

once you have stripped the motor you will need to epoxy the wires . if you don't they will break and you will need to fix it witch is not a fun thing to do . if they are not epoxied they might fail in flight .

now you will need to remove the locking grub screws on the shaft this is the most critical part . if you don't do this step and you are planning on using the threaded section on the shaft to mount the prop the bearings will seizes and fail . 

once you have removed them you will need to fit a prop or a spacer and a wing nut . when you tighten the wing nut the shaft will move in the housing . 

you will need to tighten the nut until the cir clip groove is in line with the bearings .

once it is in line you need to loctite the grub screws. now leave them over night to let the thread locker set . 

now you can re assemble the motor and fit the props . if when you tighten the props on and the bearings get tight . you will need to repeat the last step until they don't tighten up any more.

if you wanna mount the motors with m3 bolts . you will need to open the holes on the mounting base .

if you wanna mount with cable ties you will need to make some new holes . 

thanks please rate and subscribe

Interesting article but a couple of questions:
1. Why do you remove the shaft? Only to lock the grub screw? Have you got experience with loose ones?
2. Where have you put the epoxy? I don't see it on the picture. All over the wirings? Only by the exit of the wiring to the cables?

Thanks!

the shafts get loosened and moved to line up the cir clip with the bearing . they send them with spacers but the shaft slips in the housing when tightening a prop on and it causes bearing failing . the epoxy goes on the exit wires and in this case i covered all the windings aswell as the linking wires were a bit loose for my liking

Thank you for your answers. I will perform your recommandations before mounting mines on my twin float plane :)

Doh! I performed your manipulations tonight, but not in the right order and did not separate the magnets from the wiring part before to epoxy them... I have completely glued both of my motors... and now they are on BK :(
