What kind of grease do you use when assembling your heli. Any good brands.

Mobil1 synth. grease where grease is needed.

Rem-oil for the auto bearing and TriFlo or BreakFree for everything
else.

I use the white automotive lithium grease.

I never really liked white lithuim grease

I never really liked white lithuim grease. No offense to you or anything. I just always found it to have the consistancy of wipped cream sucks in dirt more. I like the thicker greases where even with a tiny layer remaining, it is as slick as, well as grease I guess.

I only use the lithium grease in encased gear casing and boom bearings. As for the exposed area of bearings I use silicon based lubricant.

Tri Flow with teflon is the way to go, it is much softer than automotive greases. The teflon makes it hold up forever too.
I also use the oil form Tri Flow, it is just awesome, I have never heard a complaint about either one.

Where can you buy that Valvoline Wheel bearing Grease? Auto parts supplier?

Here is my drop of grease.....

I agree with DavidH

You wan't something that is sticky and thick and stay with the bearing, that's way I use Midas Touch High Speed Ball Bearing Grease, Midas High Speed Grease bonds to the metal to create a nearly friction-free surface. Performance is improved by reducing heat, resisting corrosion and extending bearings and tail rotor life. For best results hand apply Midas Air Power to all metal surfaces then grease all the ball bearing with grease, you won't have to grease a bearing again!

PS. I use it in all high and low speed ball bearing including tail rotor gears.

Tri flow oil on the pitch slider for the tail and the main shaft at the washout and swash.
I use R/C car ball diff grease on the thrust bearings on the main rotor and the tail rotor. It is a sticky thick transparent silicone based grease that seems to do its job (the ball diffs in cars are similar to the thrust bearings, balls between two plates)
I don't grease any of the other bearings; my philosophy is the more grease you have the more dirt it will attract, the sooner it will wear out.

Thanks for the subject guys... no sexism intended.
I have been wondering what lubricant SHOULD be applied to keep an Ergo 30 fit & healthy.
All the bearings seem to be healthy & smooth after about 30 hours of use; apart from applying some light machine oil on the main & tail shafts, I have left the rest as assembled.
All other bearings in the system seemed to be sealed to me & I am not sure if I should try & coat these in any further " goo ".
I fly in what can be a very dusty environment & don't want to attract any more crud to the helicopter by adding attractants ( is that a word ?).
I've had to replace plastic universal links because they have ended up with dust & fuel ( read fine sandpaper ) wearing them away faster than seemed to be normal maintainance.
Any input would be appreciated....Noel

It is of my humble opinion that the grease that oozes out of a greased sheilded bearing actually acts as kind of a "seal" and keeps dirt out of the bearing. Many people say that grease attracts dirt. Let's face it, there is no magnetism between dirt and grease. If a piece of dirt happens to lands on some grease, then it will stick. If you have a small amount of grease around the small open area of a sheilded bearing where the sheild and inner race almost meet, would it not be better for the dirt to stick and stay on this grease than to be free to eventually work it way between the sheild and inner race and into the bearing?

Alan Angus

P.S. I also think that thrust bearings should have a thick grease, to prevent from being thrown off. However, I prefer a thinner synthetic for high speed bearings such as start shaft, or tail rotor as the thinner grease seems to sap less power.

Noel,
Are you operating Ham Radio as well.. looks like that's the Ham Radio Call sign.

i could be wrong.

Now that you mentioned about the dusty environment. I was just wondering in R/C helis If there is anyone manufacturing BOOT just to cover the swash plate and the tail rotor like the full size helis does.

Grease?

I like to use White lithium grease in the tail gears and the tail boom bearings, as well as, the tail slider,it's light enough for the slider and lasts longer than oil. For the high speed high load bearings I like to use automotive high pressure CV joint grease, I use the "Greaser" to get it in there.

The viscosity is high enough to stay in the bearings under a wide operateing range, although I have not tried it in cold weather, it may be a bit stiff if it's very cold; of course in a CV joint that wouldn't matter,but, in the small bearings that we use in our helis it could make a big difference by robbing power.

Grease???

Come to think of it, I posted a link about lubricants and how they stand up, I think it was on "Fritz The Cat's" site; he tried a lot of different lubes and reports the findings. It's in here somewhere but I can't remember what it's called, maybe it's in the "lube" pages somewhere? Anyone know what the heck I'm talking about? It was very interesting and had a lot of good info.

BladeRunner.... No I have no idea what your getting at in your last post... as far as I know Fritz the cat didn't use any lubricant

ouch!

Naomi...yes it is my amateur radio call sign,, it seemed less dorky than
" splash the cash " or " fly better you bastard thing " as a moniker at the time.
I haven't been on for a long time & my old Kenwood TS520 & KW 1000 linear would all probably go into heart failure if I actually put 240 volts down them.
If there are boots available I have not seen them here.

Grease?

Good one Noel,( BTW, that was a great movie-wasn't it?) I will have to do some digging, there was a fellow who checked several types of grease and how they performed. He said some only lasted about 15 min.!

He did several types of tests, something he called "spin-out" that was how well the grease adheared at high speed or someting, it was very interesting-at least to me it was, but, then I'm easily amused by shiny objects too!-Hehehe
