new alum gears for emaxx
 

Hey guys,
Was looking at this other site (didnt want to put the name cause this is mikes forum) but no need to look for the ultramaxx gears anymore. I dont know if anyone baught these yet or posted it but here it is. http://rc4wd.com/shop/product_info.p...d3385f4e417b38

DOnt know if they are any good just thought for those looking for the ultramaxx but dont want to spend that much. Hey Mike if you dont want this posted sorry about it and delete my post. Grant

if anyone got these... how are they? strong ?

I think I saw a prototype version of these a while ago. The quality of machining looks pretty good for the price, but unless they're teflon coated I doubt they'll last too long against steel idler gears.

that is the reason why ultramaxx used the brass idlers. At least, i thought they are brass..

I'm pretty sure my gen3 ultramaxxed idlers are TiNi coated steel.In fact i'm almost certain because in some areas they're steel coloured where it looks like it's worn off(probably just weren't coated properly) even though i bought them new and never ran them.

try sticking a magnet onto them, once you've got them out.

They didn't looked like nitrid coated to me, but i might be wrong.

i thought they came with aluminum idlers?

no. my gen III's had no aluminum idlers.

maybe it was a previous version but im pretty sure that i was told one of them had aluminum. i think it was the gen 1.

Squee, i dont know buti dont think any of the GENS had aluminum idlers, they were all the gold ones (brass) Someone correct me if im wrong.

as for the Ultramaxxed gear set....gen I's used a teflon hard anadization on them....but once Dan (aka Microwebtech) found out that it didn't provide the protection he wanted and that it just raised up the price hhe went with the plain aluminum....then came the brass idlers....hence Gen II's.....but after I was able to damage a set of gen II's....basiscly the gears started to ramp up were the pins from the shift dog was making contact with the 1st/2nd gears.....so then after I sent my original gen II's into dan and he replaced the gears for me...the gen III design was born and the shift dog pins are slighlty offset more to engage the gears more fully and then he inserted the steel pins into the gears so then you would have the steel to steel contact.......I have yet to switch to my set of gen III's yet....but the RC4WD site gears have a flaw.....the gears are michined too thin between the bearing carrier and the gear itself....of which i foresee the gears failing in the same retrospect as Dans gen II's did with the pin contact.....if this was a way for them to cut corners and reduce weight...then i don't think it was too smart on their part.

Gen I's were ran with the UE steel idlers...but to much wear was found on the gears...so then the brass ones were intoduced in the Gen II's..and continued onto the Gen III's....

So they are a brass alloy,i've been puzzling about this,i think they must be a brass alloy with a fair bit of Fe content?
They are attracted to my 7xl rotor but the force is much weaker than with steel,the brass rods i have here aren't attracted at all.

I think brass may be too hard anyway for the Rc4wd if they're only 6061,i'd use stock idlers with them unless there are some aluminium ones.

EDit:Ok i found out high strength brass has iron content for strength,just a few % so that explains the weak attraction to the magnet,unless it's an aluminum bronze,that has all sorts of stuff in it.So my brass bars are just copper and zinc i guess.

this is the areas that I'm saying are machined to thin....yes it probably saves weight....but I think it's more prone to failure....

Yeah looks like the drive pins (steel?) would eat into those faily quickly in our brushless trucks.Depends what they're made of,'aluminium' is a bit vague.

they appear to be just aluminum...but who can tell....I agree with you....with that being so thin...it's prone to failing...here is a little history about how my Ultramaxxed gen II's failed......basicly it was from shifting from 1st to 2nd and back, while under power....and not letting off of the throttle.....this caused the failure in my case.......and that was on gears that had more pin surface contact......and with those appearing to be so thin in that area.....i see a problem ...since alot of the peeps run BL around here.

well id dont really see it being a problem for the single speed people though. with brushless you really dont need 1st gear anyway.

True...very true.....I still run a 1st/2nd gear tranny....but most of the time I'm in second gear....but some time I'll drop int o1st when I'm doing some climbing and such.......but for the most part...it's in second.......I'm not saying anything bad about hte gears....just that the area I described appears to be weak even for a single gear application..by saying this the steel pins on the shift dog...still has to make contact with the 2nd speed gear....and it just looks weak that's all...i might be wrong......

The single speed won't mate up to the gears pictured. The coupler is different.

Thats true....the single speed conversion won't even match up to the gears...either mod the gear or the conversion adapter......

yea, it wouldnt take much though.

WOW, I'm flattered that RC4WD copied my UltraMaxxed Emaxx gears set (almost).
Yes I am the owner and the original designer and developer of the UltraMaxxed gear sets.
Due to circumstances beyond my control I no longer have the ability to produce gear sets.
I knew it was only a matter of time before they would tried to be copied and I commend RC4WD or whoever would come up to bat on a set of gears, I hope they hit a homerun.
I believe very few new products went thru the extensive design and testing that the UltraMaxxed gears went thru to bring them into Generation III.
There was a small issue with one set that was mentioned in a previous post about a shift pin gear wear problem. That was an isolated issue. It was something that I could have ignored but didn’t. That set of gears were fixed and it made me look ahead to further bullet proof my gears. Generation III were born.
My UltraMaxxed gears are being used all around the world and I have never had a complaint nor a set returned for any type of wear, breakage, etc. They are bullet proof.
A few things posted are not totally accurate. Concerning the Teflon Hard coat anodizing, it was tested and proved to have no lasting value. So that was abandoned. The original gear sets were run and tested with UE steel idler gears, wear was not an apparent problem as someone said wear was a concern, I was still looking ahead to build the best money can buy.
The whole idea was to build a set of gears that would eliminate all factors on wear, reliability, longevity and all out abuse of any kind, and be the best value. The development of my special alloy idler gears brought this gear set to a new level of strength, longevity and able to take any and all abuse. It was no longer recommended to run my gears with steel idlers when I now included a better compatible material. I set out to do my own research and development long before anyone else had the ballz to spend a penny on a new product that I saw the RC hobby needed once all the brush less motors started coming out.
The bottom line is I set out to develop and produce a product that never existed because I was tired of reading about all those plastic gears disintegrating, from speed runs or BL power. I did complete what I set out to do and it was fun while it lasted, but all good things come to an end. But it went beyond my widest dreams to produce the best gear set available. There are still a few well kept secrets on my production, that will keep them unique.
Apparently my GIII gears have a great reputation as being rare and the best made because I have found my gears on Ebay for over $350 a set.
Each set was hand inspected, test run and broken in by “me”. I had the final say on quality control. My gears were made in small batches by CNC machines, call me old fashion but I still found rejects and made sure every gear set worked before I would put it in the package. Mass production will bring down any production cost but it seems the time and quality effort I put into my gear production will never be duplicated. I made my gears right and supplied the whole package deal to do it once and forget about it.
Unless RC4WD sees and tests the gears against what I did, it will be ashamed to see all the failures. My gears will be copied but never duplicated. I guess it comes down to “you get what you pay for”.
I hope it all goes well for you but you still have allot to learn to try and equal the first the best and the strongest set of alloy gears ever made for the Emaxx.
My best regards and good luck,
Dan

Holy Cow, talk about writing a small book. It's great to see you on here Dan....

I just had to reply to what they say as "Imitation is the greatest form of flattery"
Dan

point well taken....kudos to you.....

question: how much were they new? i wasnt aware of them until we after they were out of production.

The original generations were $160 shipped free and Paypal accepted,
The final GIII with alloy idler gears and grease still shipped free and Paypal as production costs went up the price went to $200 per set.
You can still see the website at www.ultramaxxed.com

Hi Dan,could you tell us what alloy was used for the idlers? Or is it a secret?I guessed it was a high strength brass with some Fe content since they're weakly attracted to a magnet or an alumnium bronze alloy maybe.

All I can say is every time I look at the pictures of the RC4WD alum gear set all I see are flaws and a lack of engineering and just a few pieces of aluminum worth much less than the price they want. I am not jealous but again don't they care about what they are selling? Is their reputation not worth a few extra bucks. Now I know my gear sets will just increase in value as junk like this is made to be a substitute.
You are supposed to be sucked into the magic of aluminum gears for the Emaxx. Are you under their spell yet? I no longer have a gear set to offer and neither does RC4WD..........

If I remember correctly you did purchase a set from me and I thank you if you did.
Yes it is a secret alloy. And that is what made the whole gear set what it was and made it special.
The ultimate gear set made was UltraMaxxed GIII.
Dan

.....
the Ultramaxx gears will go up in value....OUCH....but well said

the OUCh was intended toward RC4WD product

Yeah i have a set of GenIII,very fine they are too,thankyou.

I almost wish I had the money to start off with a new machine shop to get this off the ground again to produce the original and best gear sets ever made and stop the "counterfeiting". I hope someone keeps an eye open and lets me know when RC4WD produces "Note: We are still working on the rest of 2 little gears, it should be available in May"
Oh they just think of them as the 2 little gears!!!.
Boy aren't you lucky to get 2 little gears to go with the other parts in this set.
That's the thought process behind this gear set, lets make everyone think they are getting "UltraMaxxed" NOT!!!!!!!!

I couldn't resist this......"All I want for X-mas is the "2 little gears""...sorry that wasn't nice.....But on a more seriuos note...how can A company produce a copied item and not even know the correct name of the product...IE....1st gear/Shift Dog/2nd gear, and idlers....

Exactly, I just hope they sell well and they get the bad publicity they deserve as they fail in minutes or less than an hour of bashing.
Poor planning and design is met with doom. I guess that is why the RC4WD Aluminum Emaxx tranny case is no longer made. It appeared to be a good design but had many flaws to fix in order to make it work if you knew how to fix them. Yes I did actually have one of them and installed my gears in it and sold it as soon as I could. I did get it to work but I was not very happy as were previous owners of the cases only had complaints. I see the gear sets to be short lived also.

Up late tonight eh...dan....It's nice to see you still around.....I remember the aluminum case they made...it was pretty expensive, but had alot of complaints.....you're right about their gear sets.....if they produced tranny cases with that many probs...by the appearance of the gears..they seem to be following in the same footsteps....catch everyone tomorrow....

Yes that is exactly what I'm taking about. It's like any China clone, there are going to be cost cut backs and quality issues. Some great things come from China and I own allot of bargains that work well, BUT there are always things you cannot compromise on and expect it to work or last. And a gear set like this is one of them. So BUYER BEWARE!!!.

Good Night

i dont think those gears are ment for high power brushless i think there ment more for crawling sense rc4wd sells stuff mostly for crawlers. and i think its also for the "bling" factor more that strength imo
