Outkast187 says: I cant say enough about these gears. I have put more power to these things than most people will ever see, and no failures. They are stronger than the rest of the drive train, so the transmission is no longer a concern. I have broke 2 SM CVDs and bent one, and broke the 6mm output shaft as well. I have put around 10 races on the truck at this time, before I wouldn't get through a single race. The quality is 2nd to none on them as well. _________________ www.bomb-proofproducts.com HiAmplidude says: I have broken my personal top-speeds 3 times because of these gears. My experiences with the gears come from comparison to both plastic and aluminum tranny cases with SM idler gears and high-end bearings. With those original gears, even with the SM idlers, I was not able to hit 51 MPH without the main gears grinding. After several times of this, I gave up trying until it was time to prototype test these things. Immediately, I was able to take my twin brushless truck up to top-speed without grinding, which just encouraged me to seek more. I slapped in a single, very powerful motor and ran it on a lot of cells to 5MPH faster than I had gone with even the twin setup. So, of course, I wanted more, and threw in an even more powerful motor, once again, passing that top-speed. So, of course, I wanted more, and threw in a motor that's even more powerful than that one, and blew into the 60MPH+ range, with a heavy extended aluminum truck. The kind in extreme output it takes to move the big ol' heavy truck this fast through the wind and across the asphalt, with 4WD and full-size monster truck tires, is almost beyond comprehension... And, to do that in a truck that is also tuned to have the torque to yank the front end of this heavy/dropped truck into the air already accelerating into speeds exceeding 45 MPH. None of this would even be remotely possible without the UltraMaxxed gears. _________________ www.rcnuts.com Promod says: Dan has a great product here!!! The gears are well made and SUPER strong!!! My dual BL motor set-ups were destroying stock gears very easily now all my problems are gone. I have used some very powerful single and dual BL systems with no trans problems thanks to these wonderful gears. The following BL systems were used when I tested the gears. Dual C50's with 28 and 32 cells. Dual Hacker L's with 28 and 32 cells. Dual Lehner 1940's with 28 and 32 cells. Single Hacker XL with 28 and 32 cells. _________________ Thank you, Promod More to come, but I think Outkast, HiAmp and Promod have said it all... Here is a testimonial from one of the 3 unknown E-Maxxers that were able to obtain a pre-production final gear set, they were chosen to provide a well rounded group of end users based on power plants, cell counts, driving style and just overall differences to represent the E-Maxx transmission durability. Shayne says: Dan, has really made a extremely durable product, that has been able to with stand the punishment of pulling massive amounts of weight around. Here are the results before UltraMaxxed gears and after. All weight was from a dead stop, with the tranny locked in first gear....no pushing was done to help get it rolling... Item being pulled : 400 Lbs (my old record) 100 Lbs cart 300 Lbs of sand Stock tranny gears...Broke stock idlers after 10 ft of pulling UltraMaxxed Gears.... 700 lbs (my new record) 100 lbs cart 600 lbs of sand The UltraMaxxed gears not only took the abuse but kept on ticking.....I was able to pull this much weight running the following system... Single 1920/8 Lehner BL motor 1895 micro BEC 12- 2400mah Ni-Cd matched cells in series Gearing was 11t pinion /66t spur If this gear set is able to withstand HiAmp's speed runs, Outkast insane driving habits, and Promod's multiple motor setups , and my weight pulling, then I think the gears have pretty much proven themselves. Great work Dan for seeing it thru till the end and Ben for your knowledge and years of work...going into the "mystery metal" which made these sets possible. _________________ rcmaniac ((sjcrss)) |
the only differance from the setup I was running when I tested the gears for Dan....is the following.....
1895 Micro Bec (Blown now)..replaced with a 2095 Micro Bec 12 cells of 3300 Nimh matched in series Gearing is 13t pinion to 66t spur UE 8 spyder diffs ... having said this...Dans gears are well worth every penny.......IMHO |
Stampy. For crawling you wouldnt need metal gears and you'd only use 1st gear for most of the time! To Be honest, we all know they were made to be used with big brushless power, and as said above there gonna fail on!
Cheers Matt |
I dont see the complaints here legit we havent even tried the gears yet? why complain about them? Granted yes dan you do make the best gears to date I bought like freakin 4 of them man used 2 of them heck my used 2 sold, sold for the same price as new man it was freakin awesom deal I sold them and make some money, but nuff said though you dont make them anymore and your critique RC4wd already and havent tried them? lets see see what happens then we can, "oh how crappy they are" I remember when the first emaxx came out you know what they said about the emaxx back in the day, "another stupid electric truck" yet it dominates the electric truck category when so many folks critiqued it badly before it hit the shelfs.

jocktheglide,
I guess you are right, only time will tell. |

I guess if I could I would, but it's just too expensive to start the process all over again from scratch with a new shop. I was very lucky the first time that I found a shop that would work with me and also enjoyed the challange. But even with them as things went on the costs went up and then I had to have a minimum order etc.
So with that said and not really having the time or money to do it again... All I can say is I set out to make the best tranny gears for the emaxx that were ever made, and I did. UltraMaxxed gears will remain a part of Emaxx history. |
Maybe you could talk to mike or the guys at fast lane machine. It is a choice to make but it could work out.

When you were first selling your gears, brushless wasn't nearly as popular or attainable as it is now, so your gears weren't necessary to the vast majority. Nowadays, practically everybody runs brushless and your gears would sell significantly better than they ever did before. +1 for starting them up again .... |
i say start making them again and maybe mike or fastlane would help you
|
Hey Micro, I bought your very last set of the GenIII. I wish I never sold it. Boy was that a big mistake. Hopefully someday you would be able to hook us up again.
|
I sold mine becuase i didnt really that super high power tranny like most of your guys did I did run a dual HV maxx, but still not as powerful as some of you guy though, but after time I sold them since I didnt need it its like buying a lambo top dog, but your never gonna hit past 100mph whats the point of having same with ultramaxx gears best there is, but I had no use for it rather take the gains from it. If these gears work and wont blow up with dual HV maxx im fine.....

The Bottom Line.
The bottom line is that you no longer have Ultramaxx gears in production for us to use. That leaves all of the RC enthusiests stranded without anyone to turn to for help. Oh, except for the one company you are bashing for trying. They might not be the best for the job, but no one else is even putting forth an effort to assist us with this problem. Now I am just one of the guys out here trying to have a good time doing what we enjoy doing. creating an RC vehicle that will not only run strong hard and fast, but get through the day without having to stop and fix the tranny after every hard run. So if you truly do care about our struggle with this delema as a team player, then why don't you do something about it. Like help RC4WD out with the design issues that they are facing. If you have no plans on rebuilding your business again, then what difference can it possibly make to you if they succeed where you left off. They have the money and the resources to carry on, and fill the hole that was left when you closed your doors for whatever reason.
Sorry for responding so harshly, but I don't see what you are accomplishing by complaining about RC4WD's efforts if you are out of the business. We RC people come here for answers to our RC problems. What do you have to contribute in answering this problem of needing tough gears for the EMAXX? Sincerely, Jerry2kone. |
Absolutely
Well said, they may well be the best ever built, but if they are no longer available then why talk smack about someone who is trying to provide something.

I can tell you right now without running those gear's that they will wear very fast. Alum on alum gear's ~ no go. The idler's should either be steel or coated/ heat treated to withstand the wear. If you put alum on alum in a tranny and use a big brushless motor it will wear, fast. There is a reason why Ultramaxxed coated their idler's. if the rc4wd gear's are in fact wear-proof like the ultramaxxed i'll take my word's back.
No company is going to make expensive gear's for an out dated truck only a few brushless guy's would run. And with the slipperantial coming up, nobody will run a tranny in the future. Atleast that's how I see it. |
i have to agree with Sneeck.....I have a full set of Ultramaxxed gears in my tranny, and probably will not part with them.....once the slipperential comes out....I will be going to that....& I'll just keep my old tranny for a future project...
|
I think the slipperential will provide us with more choices of gearing, lighter weight, single speed and one durable center diff.
Mike told me it would cost less than $200 for the whole thing. I think he'll sell it with a HB differential. Probably I'll ask him to replace it with a 8 Spyder diff. |
Seemed to me that rc4wd just tried to make a quick buck on those gears when the ultramaxxes appeared to be discontinued., not bashing ANY product, but any engineer, who is showed those gears, can tell you what it's weak point is. The ultramaxx gears where made by a perfectionist, who knew his engineering. Don't want to start a flame about it, but i am just telling it straight to the point.
I thought you US guys invented the sentence; go big or go home? And with the singlespeed conversion and the 2nd speed lock-dogg, you don't really need the aluminum gears. And with the slipperential going to be out soon, the racers are covered too. It's great the rc4wd gears are available to the large public, but they need to do a bit more to get them top-notch. (again, no flame intended, just telling the truth) |
very well put serum...
|
I have had more failures from the input shaft pins than anything.
The ultra maxxed gears can't help you there either. The steel idlers are a big strength in the trans. If you going to do some awesom weight pulling like some of he testimonials I could see. |
Yes, the pins... I don't even use them anymore..
When i get the shaft i press them out first thing and replace them with a solid pin instead of the 'break-pin' |
Also to add, the ultramaxx idlers i believe are brass, not coated....could be wrong, but mine look like brass. And "US" guys...well ummmmm, no comment! LOL
|
Yes, the latest generation used idlers made of brass.
|
I have the gen II's, they are brass, the gen III's are also brass. Very nice gears, i love'em!
|
I've alway's somehow thought they where coated. Doh.
|
The reason they are brass is for two reasons: 1) Aluminum idlers will wear too much, 2)Steel would wear all the aluminum gears out. Brass is soft, yet durable for the application, and does not wear and tear on the aluminum
|
But they must have some treatment, otherwise the steel input pinion would wear it out in no time.
|
The set of gen II's that newe has were originally mine, and i sold them to him...I ran them for several years, and he can vouch for them..that when he got them from me they looked new......& yes the only failure I have had in the trans is the roll pins on the upper shaft...
|
Yeppers, i was surprised when i got them, they were like brand new...even had the mill lines on them still with NO wear at all!
|
I discussed the drive pin issue and materials selection, thickness, etc. with RC4WD early this year. They said they would look into it but pretty much blew me off.
I seriously doubt these things will hold up in any maxx with power. If the lube is inadequate I'll guarantee that these soft 6061 gears will eat themselves alive! |
Yes, that's what i am talking about Procharged.
An engineer should listen to the advice of others. And it would be more than obvious that the choice of material and the design is inadequate. I rather put my money on the singlespeed and a steel idler than on this particular gears. Again, not bashing any products, just venting my thoughts about those gears. I stick with the fact that i see it as making a quick buck, floating on the succes of ultramaxx. |
yuppers, i agree

I woudl also like to add that the guys here contribute the one thing that matters most.................BUYING STUFF! Without that one contribution, no one would be in the RC business at all!!!!!!!! |
As one of micro testers, i can tell you that he payed for everything out of pocket, including the original prototypes.....so he was the original originator, it was his desire & his dream to take the original emaxx gears and have them made into aluminum, back when Bl was new, so that being said, he even has told me over the phone that he was suprised that no one has aproached him about the gear design ect.... so as the demand went down for the gears he didn't make any more...the original quote for the # of sets that were to be made was 75 sets...but he instead made a little over 100 i beleive...that was including the gen II's and the gen III's.... i just think that RCWD gears might hold up..but then again they might not...time will only tell...as for me I will stand behind the Ultramaxxed product
