Who makes the strongest/toughest pinions?
 

Allright, its time for an overhaul on "Frostbyte" and I was going through and stripping the truck down to its essential to look for wear and I was surprised to see what my stock 20T pinion gear had been worn down to.

Needless to say, the torque and power from even 4S is pretty amazing for it wear down like that. So I need to replace it with the strongest, toughest pinion I can buy that will last longer then the stock HPI one. I've heard lots about Robinson Racing but apparently Castle Creations also makes hardened pinions for their motors as well.

Thoughts, suggestions input would be greatly appreciated. I'd like to stay at 20T for a good balance of power,torque and speed.

I'd say go with Mike's pinions. They are hardened steel and i've purchased a couple and have yet to strip or break one.

what bore do you need on your pinions? RCMonster pinions from Mike are awsome. Well I like the ones I have a lot. Mike makes them in 5 mm bore in 32 pitch, mod .8 and mod 1. He also makes 8 mm bore pinions I think. Just check out the RC Monster store in the ''Gears/Tranny'' section.

Rcm pinions are the best. Better materials and better machining/hardening. I had a long conversation with Mike about his pinions.

wow i've never seen that happen!! thats crazy.. bash much? lol

I've tried them all, Mikes are THE BEST Hands down.

RCM again...tough buggers

Another +1 for Mikes, I've owned quite a few of them and they all work great.

Worn down 2 HPI's with my Flux on 4S (just like in your pic) now got some from Mike and they don't even show wear!! Love 'm !!

Which ones did you get?

I've had tons of pinions and I really like Mike's. I've only ever had one to wear quickly like that, and Mike hooked me up with a new one for a very good price.
Not to mention it supports the man who gives us such a nice place to hang out. ;)

+1 for Mike pinions.

I had a few wearing.
Not as bad as yours but well on there way.
I don't think I have had any of Mike's wear.
The spur may have went away fast.
Then again 12s has no mercy. :yes:

I got some 20T for myself (just like the stocker). Pity I didn't order some 22T for that little extra speed.

RCM first choice RRP second choice.

This the one I'm looking for? What makes these pinions so special vs hardened steel versions from Castle Creations, Team Novak, Integy and Robinson Racing?

the hardening process. Forget the exacts but Mike had a specific list of rules for the machinist to harden them

Integy pinions like anything else of their's, garbage.

Castles, The aluminum ones that come w/the M.M.M. are obvisously expendible. I haven't tried one of their Hardened Ones yet.

Novaks are pretty good but RCM pinons seem to be beefier,more material, broader teeth.( a good second choice )

Robinsons, again less material than RCM but are of good qaulity but not as hard. The teeth will feather over in time and wear faster.

I have some RCM pinions that have hundreds of runs and are still in great shape. Definitely show wear but still running strong !

Everyones opinions are different but these are my experiences.

Well, seems like a 'no-brainer' so far ;)

EDIT : btw, you need these right : 5mm bore, mod1 pinion, atleast that's what I run. The once you linked are different.

yeah, you linked to 32 pitch and need mod1

Ah ok, thats what I needed to know.

Allright ya convinced me, i'll give RC monsters pinions a go.

:yipi:

Hands down RCM pinions are the best! I have ordered a RRP pinion when I was ina pinch and Mike was out and it did well but was a bit narrower. I also received a test batch of pinions from Novak when they where still in there prototype stage when they first released their 5mm rotors for the HV line up. They told me that they weren't as hard as the production ones would be but wanted feedback. Regardless of all that they have held up with multiple runs on them in a CRT.5, G2R revo with mod1 conversion, and RC8T.

I rate them 1-RCM 2-Novak 3-RRP

How about hot bodies steel pinions.? They make a 26 tooth mod 1 also. They also have been lighten up as much as possible without hurting strength.

Thats what I had on the truck already

I found for 5mm shaft the HPI Flux pinion was very soft and wore fast
The Kershaw Designs pinions fit well, but were quite noisy as are the Novak Pinions
My one try with RCM pinions was on a Turnigy 36-56-2600 motor in an E-Savage, the pinion simply wouldn't fit on the 5mm shaft.

I am running the Robinson Racing pinions now on the Savage Flux, works well, and quieter than the stocker.

For the Slash I like the Losi 48 pitch pinions but I change out the grub screw as the ones they come with are rubbish.

OK, to the best of my memory on the rcm pinions.

The earliest ones were actual clutchbells turned down and pressed onto machined hubs.

Next he got RRP to make them, to a certain spec (can't remember if it was rrp spec, but I think it was) so eventually rrp started reselling them as their own.

Now he has another firm make them, to his spec. The material he uses is better than the rrp (next best from rcm) and the heat treatment is also better. And the price is right in line, and we all know Mike's service is top notch.

From my experience I have noticed much more wear on the rrp pinions that I run compared to the rcm. Got the rrp pinions at a lhs closeout for a few bucks each (would not have paid full price, that is for sure). I will gladly pay what Mike asks for his pinions, just a better product than what elese is available.

Given your use of a steel spur FB, the pinion will wear more than someone using a plastic spur. Plus the spur has about 2.1 times the number of teeth, so the pinion will see 2.1 times the number of wear per tooth compared to the spur. So it has to be considerably harder than the spur if both are to wear at the same rate.

My best advise to you would be to replace the spur and get a rcm pinion. Using an old spur with a new pinion is not optimum, as the wear on the spur (even though it is less) matches with the wear on the pinion. Yeah it costs 25 bucks for the spur and another 15 or so for the pinion, but it is money well spent, and you can always keep the old spur as a spare. Or sell it to the idiots over at savage central... They will not be able to hear the noise over the sound of their 28c 3200 mah lipos exploding under the strain...

Have you read the threads over there? From what I have read they would give the traxxas noobs a run for their money (which has already been spent on Maxamps advertising campaign). At least in the elctric section, I have no idea if these guys can tune a nitro motor or not. I would not trust half of them to adjust the tire pressure on a wheelbarrow.

:rofl: :rofl: :great:

K, ordered. Lets see if it lives up to the hype :sarcastic:

I tried real hard to come up with something really easy to do that could also be screwed up... And I came up with a wheelbarrow tire. Guess I had too much cold medicine yesterday.

You too ? Ugg, being sick sucks.
I guess I was due, ben almost 3 yrs since I had the flu last.

Freeze, You'll be happy with your pinion purchase.

You said you had a hpi pinion not hot bodies unless they are the same company or something. My hb 26 tooth pinion looks alot different and better made than the 25 tooth savy pinion.

Hey Linc, do you know if Mike's gear place can do other gears other than pinions? I'm assuming they make the spurs for his slipdiff.

Before the HPI bulletproof diffs came out, I wanted to talk to him about making a machined version of the Cen R&P as they are just cast metal. Prolly not a whole lot of value now tho. However, given the success of the RCM pinions, I'm sure there are some other apps RCM could make top notch gear sets for.

Hit him up with an email Finn.

Hot bodies = HPI. Same company, different offset product with different name.

Next time I come up with another clever idea, I will. Don't stay up late waiting tho.... :)

RCM pinions are the way to go. they last FOREVER. IMO, they are much much stronger than other brand pinions. here are 2 pics of my older pinions. The first one wore to that from a like new state in about a week. with a fiegao 8L on 5s. The second one is an interesting story. I was jumping my buggy, and tried to correct it in the air. I didnt let off the brakes in time(and my brake endpoint was very high too) and when it hit the ground, the CC2650 kept the pinion almost stopped, while the car rolled, and the spurgear ate through the pinion. Needless to say, thats what happens with non-RCM pinions. Leave the integy pinions for the maxamps racers.
