It's completely normal to have some residue on the idlers. You're good to go! If it bothers you, clean it off. I clean mine sometimes.

Good point! Always lube belts with food grade silicone. This will keep the belts supple and increase life.

I'm curious, what exactly is "food grade" silicone?

It means in case of a Zombie Apocalypse, once you treat your belts, they can be eaten.

Seriously, it's just a grade of spray that does not harm rubber or plastic and is safe for incidental food contact. That it doesn't harm rubber means it's safe for belts and won't accelerate rotting by breaking down the belt's rubber.

I use the CRC stuff.

Please do not lube our belts the small rubber particles on idlers are normal as we are using neopren belts. The belt isnt wearing at all just keep flying it.

Thanks for the replies.I had a look last night,I also get quite a bit of rubber build up in the tail pulley teeth.it seems a couple of teeth have more build up then others and make the belt run a bit distorted or tight in that area.anyone else notice this?

Seb,

Why? I've always used food grade silicone spray on belts with no detrimental effects and so has Ah Clem. Is there a specific reason?

I just found out the CRC stuff I've been using has a petroleum based propellant in it. While everything except the spec sheet my teammate Saje sent me said it was safe for "most" plastic and rubber, I'm stopping its use.

Thanks to Saje!!!

Do you find that you have to run the belt tighter after lubricating it?

I have to go with Scott on this one. With the deepest respect to Sebastian, I have been lubing belts for years with no issues.

The reduction in friction and lowering of static are the reasons I do it.

A small amount of rubber residue on the idler pulleys is normal-a large amount is not.

A large amount would indicate a pulley that is not rotating freely or a belt which is too tight.

The belt does not require tightening after lubrication (remember, a cog-belt is actually a gear of infinitely variable shape). The belt usually requires tightening a bit after break-in (usually 5-6 flights and then almost never after that,with the exception of extreme temperature changes).

Properly lubed and tensioned tail belts have no more drag than properly set up gear-driven tails:

No problem Scott. I would recommend the Trident brand stuff that comes in a non-aersol pump spray bottle. This is the only spray I know of that contains no petroleum in the propellant...

I think that the aersol guys get away with using petroleum propellants because the petroleum chemical will likely evaporate off of any non-porous substance very quickly leaving no resudue. If placed directly on a belt though it will likely soak in a bit before it can all properly flash off.

With respect to the guys that lube their belts that's very old school. Too much lube on a belt can cause it to slip and creates a mess.
I've got over 500 flights on my BT700 and never lubed the belt once, much less for any of my other machines. As long as you keep them out of direct sunlight they'll last virtually for ever

You should put "Your mileage may vary". I've had belts on my old Gaui 425/500/550's slathered with silicone and had no slips.

Same here with Compass, Align, SAB, Kyosho, Mikado, Hirobo, Velos, EXI, Thunder Tiger, MA, and others.
