In the process of building up my first Fury Expert 60 kit. I am getting ready to install the thrust bearings on the blade axle. The instructions call for synthetic grease (MA #4707) on the bearings and dampener o-rings. It probably calls out this same grease during other parts of the assembly. I have used petroleum grease "vaseline" on other helicopter builds but I am not sure if I should in this instance. Would it be advisable to order the MA grease or is there a suitable alternative I can use? Maybe from a hardware or auto parts store? I will check with my local hobby shop to see if they have something for helicopters. They may have some sort of grease for R/C cars that might work. Thanks.

Grease

Any kind of high quality grease is fine. I use SLICK 50 grease on my thrust bgrs and tail box. Or u can go to the local auto shop and buy a high quality wheel brg grease.Preferably a moly based grease. U can get SLICK 50 grease at the auto parts house also.

gotta agree w/ DH (of course). I tried
and ruined a couple of radial bearings
while using Slick50. It's just not
the right tool for the job although its
OK for tailboxes.

And of course, in the heat of battle,
if you pull out Chapstick or DoorEase
when your supposed to pull out KY,
you are in BIG TROUBLE.

Lubriplate White Lithium

I have had this tube of Lubriplate White Lithium bearing grease
for about ten years now. Still got 3/4 tube left :-)

My dampners seem to like it, as well as any bearings.

Lithium?

Doesn't lithium grease have a petroleum base?I bet it does..Try Mobil 1 synthetic universal grease.It comes in a gun tube at just about any auto store for around $5/tube..Actually, you can use what ever grease you want (right thickness) on thrust bearings but as far as dampeners it must be synthetic.Now if the dampeners were made out of a synthetic rubber instead of natural then you could use what you like.I was right, most lithium greases use an added carrier oil (petroleum based).Have fun...

Yes, Lithium

Whatever this particular grease has in it, it's obviously safe, since I have
been using it exclusively for ten years. While I can't speak for all heli brands, I can say it doesn't affect dampners from MA or TT.

I had one set of Dampners (upgrades from Rick's) installed in a Raptor 60 for two years. How long is it supposed to take for the dampners to degrade from Lithium Grease?

Whatever works, I guess

Ok......

I couldn't care what people actually use, I was just stating that Lithium grease does have a petroleum based carrier oil.However you use this info or feel about it is up to you.I myself have seen people use Booty grease (vaso ) and all comes out GOOD in the END!
