Lubricating motors on IRIS or IRIS+

I was wondering if it is necessary or recommended to lubricate the motor bearings on IRIS or IRIS+?
If yes, how often should the motors be lubricated and what is the best way to do it?


I just stumbled over the Tiger Motor warranty information: … 904/6.html.

Read the last two sentences:
“In order to achieve maximum life usage, we recommend users make sufficient gap during installation to avoid binding and put a small drop of lubrication oil on each bearing for every 5-6 flights. The pilot is responsible to ensure that the bearings are properly maintained.”

Anyone from 3DR having any advice on this topic?

I would also like to know this?

I am also interested. Especially since my IRIS+ spent the night in a tree in the rain.
