In the E5 manual page 37 it says to apply grease to the Thrust Bearing Ball Race, the 5x10x3 radical bearings have no grease in them.

Do I apply grease to the Radical bearings?

"sealed" radial bearings are greased, IF not sealed, then yes.

I have no experience with radical bearings other than when boating in the Bermuda triangle and grease was the least of my worries.

Light grease in sensible amounts is fine. Since that moves over time, I have personally gone to using Dry Fluid on them.That works extremely well.

They are not sealed I can see in and they have no grease at this time.

That’s pretty “radical”. On the other hand, I would grease those radial bearings.....

Been there, done that and old enough to know better.....

There is a hole in the blade grip. If you inject grease into it, you will take care of the thrust and the radial bearings all at once

IS there a device that is used to force the grease into that hole?

That is new, I just looked at an older E5 and it does not have the holes.

The holes in the grips are designed to be used with this.

Not all models had them, it was a bit later introduction

Tail grips with holes appeared when the 766 released. The root bearings will be tougher to grease via the hole due to bearing position in the grips.

The Botolube tip will inject into the hole. Tail assemblies throw out grease quickly due to high rpm. You could add grease routinely on a monthly basis and not be overdoing it. I will wager that many models lacking such tail grease ports, whose tails are working fine, and which are not torn down from frequent crashes may be neglected for multiple seasons. It's amazing the tail bearings, esp the thrust races, hold up as well as they do running all but dry.

How small is the tip opening of the greaser you posted?
