[TowerTalk] Prop Pitch Grease preference or recommendation

[Steve Bookout]

Hi Mac,

I've rebuilt several P/P gear boxes and have had issues in the past with 
the grease being too thick in the high speed planetary gear area.  When 
the wx would get really cold (for VA) in the teens, it would want to 
turn so slowly that it would 'fault' the Green Heron controller.  This 
was when I had it set up for 'ramping' the speed up/down.  I would just 
have to change the 'ramp' setting to get it working again.

So, the last time I did any, I did a bunch of research and found Amsoil 
Arctic grease. 
https://www.amsoil.com/shop/by-product/grease/arctic-synthetic-grease/ 
The performance ratings are fine and comparable to other greases, but 
it's good for really low temps.  The viscosity reminds me of hair gel; 
not really thick at all.  And, it synthetic!  Temp range of -75 to 315 
degrees F.

I put this stuff in three small P/P's, but have not used any of them yet 
(spares), but I think it will be a fine choice.

Hope this helps.
