Which Pinions
 

What make of pinions do people use and why.

Are there benefits to using ally over steel (weight obviously, what about noise and wear???)

I use the one DC Racing have in stock at the time I order them ... LOL

Ali pinions are great in the short term however they do tend to wear quickly. Steel last longer but heavier.

With modern motors I belive that the difference between an ali and steel pinion is not an issue, sure somebody will disagree though!

having a heavier pinion is better than no pinion at all :D:D:D

I once got a titanium one when thats all the shop had in, same price as normal ones aswell.

And what did it wear like is it noisy is it light heavy?

I use the tamiya ones that come in pairs. Very good quality and nice and quiet too!!!

i've found that the tamiya corse pitch ones wear badly. But the fine pitch one are fine.

Edit are making some EXTREMELY light weight ones, they're highly recomended, not sure on availability yet though. Sure Adam can hrow some light on that side of things. ;)

I like the RW Racing pinions and have used them for years, have even got some SRM Racing gears which was their previous name.

I use rw racing ones

I think i use the Rw ones also.. to be fair, I bought pinions when I started.. and i'm still using the same ones now, that's a good near 8 years now.. and i've never found a need to renew them.

My RW ones have proven very hard wearing, I had them 20-odd years ago (think they were under a different name then, SRM or something?) and also currently.

The quietest pinions I have are the Kawada ones.

The only ones I would not recommend are the plastic pinions made by one of the american manufacturers, they wear like crazy and have an oversized boss too.

I use RW too from Castle models. When I got my brushless and knew I was never going to use anything over a 23 again I bought all new from 15 to 23 even though I had them all already, I really felt I was splashing out too :)

But I've lost one by lending it to someone and them not giving it back, anyone going to own up?

i use them too the ones from peter. they sell them at our local model shop too

I want to replace all mine. I currently have a variety of brands, some of which have mullered grub screws, some of which won't interchange grub screws, and so on.. I had a pinion fall off for the first time in years last weekend.

I am interested in the Edit brand, wonder if Adam can throw some light on it for us? I get the impression that there stuff is made to the highest quality.

pete is our local model shop garry :D

i've being using losi pinions and rw ones i do think the rw ones are better car seems to run quiter with the rw ones on :confused:

paul :)

I know where you can get new grub screws ;)

Pinions
 

Chris.
Adam [ and few others drivers] as been using the Edit brand for a few meetings and so far we have had no wear problems. I like the through mounting which means that if the thread wears in the Pinion you can mount with the screw in the other side. I beleave they will be available in the New Year. They will be in use at Worksop on the 6th.
Lindsay. :):)

i have run the rw pinions for years and like others still have some srm ones as well :O. althought the idea of the edit ones being able to use the other side when they finally strip out will have me trying them ;)

Yup, me too.;)

Losi true pitch got em last year seem OK
but i have some rw ones, from when i raced 10-12 years ago
all still OK
ish, odd grub screw missing

These should be out in the next month or so....

They've been designed with the following in mind:
Minimum Noise
Minimum Mass
Minimum Wear
Maximum contact area.
Minimum Cost!!!!

Jimmy has pictures of these pinions.

They are about 65-70% lighter than a standard pinion..

To give you an idea the 19T is 1.2g!!:D

That sounds intersting so what material are they made of how have you reduced the weight are they as strong as a normal pionoin???? Come on jimmy get them pics up.

A

.......and if you could just supply us with some CAD drawings too Adam that would be super! :p:p:p:p:p:p

im definatley likin the idea of these edit pinions. Do they have two grub screw holes?

lil ben

Can you let us know the part no's when they're out Adam??
Cheers

Sure!!! :D

Material = Unobtanium

Part Numbers : ED200XX0

Substitue XX with the number of teeth you require.

Yes, they do have 2 grub screw holes... The weight of a hole is closer to the weight of a grub screw in a hole than the solid material... Better balance.

those edit pinions sound awesome, any idea on cost?

i see. Who would of thought a pinion could be engineered so much lol

lil ben

£3.99 RRP

cool

A

cool, might have to be gettin some, could do with some new'ns

Ill be getting em :D:D:D:D:D:D
What sizes are their.

lil ben

All the popular sizes most likely

Put my name down for 1 of each 15 through to 25 please.... (Adam: would you be able to give us a nod which/when shops have them please?)

Unobtainium is a humorous colloquialism that refers to any extremely rare, costly, or physically impossible material needed to fulfill a given design for a given application. The name is not a portmanteau but it is derived from unobtainable + ium (the suffix for a number of elements). Variations include unobtanium and unattainium, with the same meaning.
The properties of any particular "unobtainium" depend on the intended use. For example, a pulley made of unobtainium might be massless and frictionless. However, if used in a nuclear rocket, unobtainium would be light, strong at high temperatures, and resistant to radiation damage.

Must be good stuff then :D

wtf? :eh?: [just about somes that one up i think :D lol]

Anyways back on subject. Will their be a pinion as big as a 29?

lil ben

for ya 540 car ben?

indeedy
