Hi experts,

I remember the instruction to build heli says that do not use lube for gear, belt or ball links. Recently, my friend told me that I should use lube for the belt even for gear, this will improve performance. I have both electric and gas heli. My question are

1. Is it true and good practice to use lube for belt?
2. If so, what type of lube? How often?

Thanks for feedback,

Some people may spray on some lube on a tail rotor belt, but only to minimize any radio interference they may be encountering.

Metal to metal gears in sealed gearboxes will need some grease and thrust bearings should be greased, but open gears should not be oiled, as this attracts dust and dirt, and increases wear. There is plenty of self-lubricating qualities on the gearsets.

Servos gears can be lightly greased.

One-way bearings/sprag clutches should be lightly oiled.

Don't lube ball links for the same reason; if they're tight, use a ball-link resizing tool to get a good fit.

use a silicon spray lube for belts and silicon grease for gears,only apply small amounts.do not get on ballinks.use white grease for bearings and sliders.# in ! oil for general lube points such as main shaft and swash brng.dont over do it!!

Ok. I gotta ask. I got trounced on before about lubrication,but I dont understand why anyone would lube a belt unless its some kind of Armour-All effect. Belts by their very nature are designed to grip,and it seems to me that any type of lube might make them slip.

the issue with the silicon on the belt,reduces friction , mostly it eliminates static electric charge.

lube or not

I lubed my e flight cx (i know this is not a large hele like yours but may (speak to setscrew and other hardware know mater the size )but all the set screws ant bearing housings {wher the outer race of the bearing fit comes in contact will start to have a looser fit then it is suppose to have )don,t get any oil or grease in the outter bearing or even in the inner race (journal )i took mine apart and cleaned all bearing fits works fine this comes from a begginer but true.

Silicone spray does more than just prevent static discharge, it made my headspeed increase a little over 100rpm. So in reduceing friction, it adds efficientcy.
