OTB is the best available. It is expensive but worth it.

If you are looking for a less expensive alternative try the RRP products. They are well built and are affordable.

Have you thought about your slipper and diffs as well? If not you will be.

When it comes to performance parts demonspeed874 would be the man to talk to. He just needs to open up a bit more in his posts.:hi:

 

[SuperMaxx97]

yes, i have been thinking about them. i am looking at the UE 7.5 diffs. they are a little spendy but they look like winners. as for the slipper, do u have any in mind? what do u run?

I'm running an E-Maxx RRP double slipper on my CyberMaxx 66t. Going smaller than 72t helps keep some of the torque off the transmission.

For diffs I'm using a full Kippster / RRP setup. I'm hopping as soon as the Kippsters give way (They are holding strong) OTB will have an alternative.

ok, i was alittle vague. hold on just trying to help.

what i am trying to show you is what your looking for. industructable tranny gears with the ability to select the gear ratio. want the ability to pull your car down the block? here is proof of the strength http://www.rcrevolution.com/phpbb/viewtopic.php?t=377
then change the gearing out to go race the following sat. otb is working on releasing the infinity foc. the final part the complete industrable tranny. question is, want to pull stumps, then change over, show off on high speed runs? makes it suitable to get the perfect set up for the track.

the only other metal tranny gears i would sugest is rrp. they are ok, and will hold up to the power of the big block. the only bad issues i have heard is they have machineing problems from time to time. look at the face of the gears and youll see machine marks. does not mess with the integrity of the strength, but might cause some slight metal particals to show up in the tranny case. just tear down and clean regulary and it wont be a problem.

in either case, you can't go wrong. rrp is a good back up for the budget racer.

now, i understand your also looking in to diffs. in the aftermarket you have 3 options. kippster, maximizer or UE. running a big block dosnt have to push you to going 1/8 scale. the kippster are ok, alum diff cups, with the rrp ring and pinion moded for 3 mm screws. the new traxxas ring and pinion are actually stronger then the rrp. rrp has a tendency to shatter, the traxxas has better wear and no shatter problems. but the travvas needs to be modifyed to accept the 3 mm screws for the alum diff cups. http://www.maximizerproducts.com/Diffs.html
i actually believe that maximizer are better then the kippster, they use no pin for the spiders. direct replacement for the plastic stock cup, along with the traxxas ring and pinion moded for the 3mm screws with a properly shimmed diff in an aluminum diff housing would beable to hold up to the big block.

or you can spend on the UE 7.5 ultralight houseings, then run the stock gears in those. then come time if you wanted to upgrade you could put the 7.5 gear sets in those.

if i were to set up diffs, it would be dynomit diff cases, maximizer diff cups with traxxas ring and pinion moded to use the 3 mm screws, and shimed the best they can.

the 24.7 is a stout torque monster. lots of power, strip gears no problem with that engine.


i hope i have helped. trying to type this and the kid wont leave me be for a few min.

Good Choice! Thats what I just built to be exact. I also used the Kippster shims! Mine are currently in UE cases, but, I have the Dynamites as well!

The OTB gears for the tranny look INSANE, and If I could be a tester, I might pick them up. But for now, I just can't drop that kind of cash on tranny gears ( I would want the COMPLETE set! ) Take note, there are 2 different tranny gear sets from RRP, the alum. and hardenned steel. Hardenned steel is the better of the 2.

very good information. i am working on upgrading all of my diffs and my transmission right now but i dont know how long it will be before i can. i will just run stock for now until i can get money.

thankz u guys

oh man, forgot about the slipper. for 1/8 scale the best way to go is the strobe slipper http://bellsouthpwp.net/L/o/LooseScrews/extreme/
for 1/8 scale gearing.

http://www.kippster-racing.com/ the best slipper set up for small blocks. i have not found the proper information to mount small block clutch systems to big block engines. but i know there are people out there who have done it.

again hoped i helped.

I'm all over the place, day in day out. from here to traxxas to the engine forums. i try and hit all the bases.
problem is trying to remember the correct information.

sometimes i try and lead people to the information I'm trying to give because there might be more information that people might need or read or just trying to generate interest in the sight. as with rcrev. nothing wrong with visiting more boards. i typicaly go between here and rcrev just because i love to consume information.
few other boards i visit also, traxxas for a good laugh, and http://www.rctech.net/ . not spaming, but i love to read. the more new information i can gather the better.
i also try to be unbiased in my opinions on products, but if something is a down right piece of crap i refuse to promote it.

rcnt and rcrev are the 2 best boards i have been on. sme fun people to be around.

demonspeed874,
Why do you prefer the maximizer cups?
When I looked at a pic of them they looked just like a stock cup but made of Al.

I have always has issues with the spider shaft digging grooves in the side of the stock plastic cups. My thought process told me that a metal shaft would dig into the AL just as it does the plastic but not as quickly.

I chose the Kippster cups because of the spider shaft is fixed to the cup not allowing it to move and cut into the cup. What is your opinion and why do you prefer the maximizers?

Thanks in advance

the reason why i perfer the maximizer over the kippster is the user aspect of the part.
the kippster when assembling have the pin that needs to be red loc-tighted in the cup to secure the spyders. not completely a bad idea. but in time can have its problems, expecially if the person dont have a regular maint check they do on their truck.
if its not secured properly can and will back out over time and that would destroy the spyders and posibly damage the cup bad enough and need to be replace. the only other issue on these is the hole and threads for the pin. a gorilla armed person strips out the threads, cup is shot.

I'm not saying the kippster are a bad product, but not a good product for the novice.

maximizer diff cups are a direct replacement for the stock plastic cup and dont have the pin for the spyders that the kippster do. basicaly a drop in aplication with the only thing needed would be shiming. these make it more user friendly for upgrading. and less worry about destroying anything.

if maximizer where out at the time i got my kippster, i would have went that rout. when my kippster fail me, in go the maximizer.

i know there are wear issues with the steel on alum. i guess the only thing i would say is a very light polishing on the pin should take down any imperfections. in turn should allow a smooth surface for the pin to run on, and that should dramaticaly reduce and galling between the pin and the alum. i use a moly-teflon grease from the automotive store in all my diffs for lubrication, so far i havnt had any problems.
