| I don't know if there's a best way, but this works for me.
I put a few drops on the hub side of each tail rotor grip, right on the shaft itself actually, and then rotational forces will ensure the oil flows through the bearings. As for what oil, I happen to like Tri-Flow myself.
I lube them before flying begins for the day, and I also put a couple of drops at the swashplate and washout since they move up and down on the main shaft. Every once in a blue moon I also put a few drops at the main rotor blade grips - the same as for the tail rotor grips, i.e. right on the shaft and let rotation distribute the oil throughout the bearing. I suspect this may wash some of the grease out of the thrust bearings, but hey, I have to repair crash damage with sufficient frequency that it's not been an issue for me!
Does depending on rotational forces to distribute the lube work? Well, it sure seems to for me because following the first flight after lubing them using this method, I have to wipe the roots of the main rotor blades as well as the tail rotor blades to remove what lube washed through the bearings.
Anyway, that's how I do it . . . and it's not just for my Tiger, but for all my helicopters! The reason I lube so frequently is because I spray down my helis with denatured alcohol after I get back to the shop and folow this with a jet of high pressure air (air compressor) to squirt things really nice and clean. Since it seems to me I may very well be washing away the lube along with any oil and dirt on the model, I figure the best thing to do is just re-lube these points before the start of flying for the day.
I guess we now have the basis for another addition to the addendum, eh?
