How to replace DT750 DT700 DT850 bearings

Hi guys!

I was getting lots of vibrations from my Hextronik DT750 even after balancing it and using balanced props. I replaced the bearings and now the motors are like new!

The steps for DT700 and DT850 are similar

I've done a video showing me disassembling the DT750, changing bearings and then reassembling it:

Hope it helps :)

Cheers!

Internal diameter: 4
External diameter: 8
Height: 3

4x4x8 may work since is just 1mm taller, but I've already replace with 4x8x3 and it fitted perfectly ;)

Aha I see :D

Will totally consider this for my quad! I assume the motors run more silently with better quality bearings?

Actually I was getting a strong vibration after a specific RPM, even after balancing the motor and props.

Just had to replace the bearings and the problem was solved! They now run more silently and with less friction :)
