I keep seeing posts about people spraying the belt with lube....I have never sprayed anything on any belts in my helis...my MT has at least 500 flights,1 year old and its still the original belt that came with the kit......I'm on my 3rd belt on the HBK(just installed #3)the first two were retired because of mechanical issues....1st one slid of the pulleys and got mangled......after about 7 months the 2nd got mangled in the rock throwing incident........I'm not saying its wrong at all...just curious who is lubing the belt and who isn't........I have read that these belts are meant to be run dry and require no lube,also lube attracts/accumulates dirt and leads to more problems......just a poll...who is lubing(not in your bedroom).....since I have had 0 problems with either belt I am going to continue to NOT LUBE but I'd like to see the responses....also on s side note....after a year of many many flights I just replaced a few bearings on the helis,only 1 was a tail bearing.....?????????

The belts are similar/same to the belts I use on my CNC machines (just smaller) and they don't need lube to perform. I think the benefit in our case it that the heli crosses the belt within the tail boom, and the lube help reduce friction of the belt running against itself at that crossing. If you had your tail out of square (thus possibly increasing the "rub" area) the lube might help belt life and result in less load.

I use silly-lube - and don't see much dust dirt, likely since it dries quite a bit once applied. I'll bet a petro-based lube would though since it would tend to stay oily.

No lube required for me either. Maybe the belts are better these days? Cannot seem to wear a belt out. I finally broke my first belt a couple of weeks ago after a bunch of flights and crashed.

As I see it, really no friction in the system. The 90 deg. turn in the boom may cause some incidental contact but not much to worry with IMHO.

Nors is right.

Certain heli's are prone to static reset ussues with Spectrum RX's.

TREX 500. EP 100. for example.

The first belt I had, was fine running dry, but when I replaced it, the new one never stayed in place, always came off until I lubed it.

picks up dust and dirt. Should be no reason to run lube. I had over 550 flights before a belt started to shred a little.

There are no shortcuts in Helis. Just good hard work.

I have always kept mine lubed with silicone spray. It seems to run smoother across the idler bearings. I have about 100 flights on this belt with no problems.

Now mfcrash was having issues with his. During his first few flights her was running the belt dry and it was slowly shaving off one side because it was not aligned exactly with the idler bearings. SO we sprayed it good and no more problems. I know that this may be considered a band aid fix instead of truly fixing the mis align bearings but hey it works

my belt had the guide issue and it carved a deep groove in it early on. no lube still runs like a champ. i even bought an extra belt and told my self that as soon as i crash and have to go through a tail assy. id replace but havent reall needed to service the tail yet. its been 8 months so far. as soon as i get a rec and servos ill fly it again. i had to cannabalize it for the new belt. good thread

I wish I was good at this

I'm lubing the king bee (nope...couldn't type that with a straight face) but am not sure it makes a difference either way. Figured it couldn't really hurt.

The bigger issue was the belt was slipping off the bearings by the main shaft. Adding a couple little washers seems to have solved that, although now it's a little frayed.

I run Tri-flo on the belt, the bearings and even a little on the main gear. Don't over do it otherwise it gets messy. I started lubing the belt when it was new and there were tons of posts about it slipping off the idlers. I had that problem once, and the belt got shredded. When it happened, it had been a LONG time since the belt had been lubed.

I know I might take some heat for lubing my main gear. But I love a quiet heli. I keep it clean and there's no problem with dirt.
I'm still running the same main gear that came with the kit and its still in fine shape after approximately 150 flights.

to me, that sounds like a better idea(lubing the main gear) but I cant see anything staying on the gear at 2000+rpm....I asked that question back in the BLADECP days and I was told the lube will fly off in about 2 min leaving a nice residue for dirt/dust to cling to...which will lead to short pinion/gear life.....I would think it has a lot to do with environment...if you are flying inside or in clean dust free conditions...but if you fly where TJ does....could be bad news


I used to ride motorcross bikes and keeping lube on the chain was a major PITA

Everything I've ever read says you cant use too much lube.

My King is one big oily grease ball well not really tri-flo silicone lube isnt very greasy. I shredded my belt by sticking my tail in the dirt right after I purchased the king I ordered 2 belts and replaced the worn one cause it kept slipping off. I lubed it and still running it today. So that would be wild guess 400-500 flights since august of last year.

To each his own but 3000+RPM at different points some less some more with no lubricant against friction parts. Just doesnt seem right to me.

Sorry fender just my Illogic logic.

If you have a nitro can I borrow it?

OOps reply to later post. If you road motorcross and werent buying the RK X-ring chains you know how fast a cheap chain stretches and links get longer and wear sprockets.

As for oil slinging off and leaving residue thats insane. the residue is still oil.

hey..it was the BLADECP forum...I'm just relaying what I was told....but if you think about it....what would dirt stick to most...a clean gear or gear with oil/grease residue on it???....me thinks the oiled gear will attract more dirt


I've never heard of anybody lubing the belts on a car and they go for YEARS under harsh conditions and weather extremes...so take it for what its worth

TRYAN...do you lube the belt on the HARLEY???

Well Fender, you make a good point. I think the question we may need to answer is why does lubing the belt prevent, or reduce the issue with the idlers.

The idler issue seems to only with the HBK2. So other helis probably don't require it unless the owner is attempting to reduce the static (lets not get side tracked).

Judging by the varied responses in this thread and many like it, lubing does hurt and how much it helps is difficult to assess. Of course, excluding the HBK2 idler issue.

In the end I'm with Tryan. If I could get away with soaking the entire heli in Tri-flo, I'd probabky try it

I'm also wondering about the Harley belt as its a toothed belt like the tail drive on a heli. Most automotive belts are grooved.

Silicone spray for belts and for swashplate. Dirt doesn't tend to stick to to silicone. Why run Dry when there is silicone . Why not minimize friction when you can- friction wastes's energy

Because there is no friction?

Lets be real here. There are millions and millions of unlubed belts out there in the world and the King belt along with static prone TREX 500s need lube.

So we have guys reporting 500 flights without it, why do it?

I just put a flight on the lubed king and loved it twitchy little thing.

Oh and fender you never heard of anyone oiling there car belt thats very surprising where do you work again?

Sorry to hurt your feelings fender but Im hopped up on an amazing day of flying.



Oh and greggor the Harley toothed grooved belt is kevlar impregnated and about 1/2 inch thick 1 inch wide. turns way slower than 3000rpm harley uses chain drive for high rpm engine internals timing and primary drive all bathed in oil.

If you have a nitro can I borrow it?
