In the past, I believe people never oiled the bearings on high quality motors like the Actro, Pletty etc. One issue is that sealed bearings are often greased properly and do not need it. Furthermore, adding oil could wash out the grease and actually shorten the life.

On my Hacker motor in my Trex 500, you cannot access the lower bearing without removing the fan.

I have an Actro 32-3 and am wondering if I should oil the bearings occasionally.

What is the current consensus?

I have four 32-3s and have never oiled any of them. Not sure why the Scorpion motors need to be oiled, except that their bearings must not sealed and require oil periodically.
A few years ago Hacker came out with what they said was a Heli motor, but could only do 14,000 rpm. After a few flights the grease started coming out and their answer was to add oil every few flights. It didn't take them long to come out with a motor that could take the higher rpms.

It takes me a whopping few minutes to oil the bearings in my Scorpion HK4035 once per flight session or so. If that's all it takes to maximize bearing longevity, I'm in.

I don't on the kontronik motors or high end motors but hot running like the scorpion i do, as well as replacing bearings every 100 flights (4035 motors).

Scorpion did have some bearing problems but this was really due to poor quality bearings, they changed supplier a long time ago and i do not think its as much as a problem as people think. I think the heat and high power from the 4035 in 90 size heli require oiling/bearing replacement, only the lower bearing gets rough.
If you can run a counterbearing and the bearings will last longer.

Correct.

The true story of what happened with Scorpion is that the company had a period when they were sourcing supposedly branded NMB bearings from an unethical Chinese distributor. Apparently the company sent Scorpion a batch of fake NMB bearings. Of course, they failed in no time at all. Once that issue was resolved, bearings problems fell dramatically in incidence. Mine are doing fine.
