RC18T Steel Diff and Input gears Yes/No - 5/9/2008 3:18:35 AM

Hey,

I was wondering, I already have ordered some Super Diff kits from MIP for when my diffs go. But I was wondering. Is it a good idea to also order the steel input gear and diff gear. Or is it a bad idea. I thought it would be good because the Savage has steel diffs and pinion gears. And think maybe it may not be any different, but what do I know.

Thanks
Shawn

Will it make the drivetrain stronger ? Yes , but if you shim the diffs correctly the plastic gears last a long time .

Are you going brushless ?

I have them in my RC18 and love them as well. They are a little tight at first so you kind of need to break them in. IMO you also need the titanium spur gear as well.

I wouldn't, especially if your not experienced in shimming the diffs. If you get it wrong, thats at least an $8 mistake instead of being only a $4 mistake, and if your parts aren't from a local lhs, thats at least 3 days lost due to shipping. Then its back to shimming, this time you should get it it almost perfect, but you won't really know until you get some run time on it and re-examine it. I'm running 4S and the stock gears work great.

If you want your drivetrain to be stronger, do some searching about putting your plastic gears in boiling/hot wire. The good thing if it actually does work, its basically free!

TheToyz just got some in stock, after not having any for months. Order quickly if you plan on getting any. Shims can only do so much. A steel input gear is a steel input gear.

I was also wondering if it would be a good idea to use the steel input gear with a plastic diff gear. Wouldn't that make the input gear last even longer. That is the piece that always strips out. I have a bunch of diff gears that are still good. It sucks that nobody sells the input gear by itself.

Comparing your Savage or any other nitro to a RC18 is kind of silly as they aren't close to the same thing, scale or power source, and the reason most nitros have steel diffs is because of the power and torque generated by those nitro engines while the electrics (especially the minis) don't have the stress concerns. AND, if one does go to steel diffs then they have to realize that part of their now increased routine maintenance is greasing the diffs since metal on metal wears if it's not lubed regularly and properly.

Personally, I wouldn't waste the time or the money. People that properly take care of (and thus maintain) the stock plastic diffs get plenty of service out of them, I have the orginal set of gears in mine that I've raced for two seasons, and plastic diff gears are really cheap to replace while the steel is expensive. Save your money for something more worthwhile.

I agree 100%. 2 steel diff and inout gears is $28+ shipping from the toyz. Its pretty inevitble that you might need one more just incase the shimming isn't right, so thats $42 + shipping. Thats 14 stock plastic diff and input gears.

I'd personally use that money to buy some CVDs(if you don't have any yet) or the new Exotek slipper

Even metal gears will still not be happy if your punching the gas while landing a jump or doing full throttle from a stanstill. The slipper will alleviate the load and keep your drivetrain happy

The slipper is a great idea for saving diff gears. I don't use shims on my diffs, I know crazy. I boil and haven't replaced them yet (20 packs). I run a Tekin mini rage and a Tekin 6.9kv or a hyperion yc22s 5000kv, I'm only running Elite 1500 nimh so I might be replacing gears more often when I go with a lipo. I had the diffs shimed before and couldn't figure out where my drivetrain was hanging up, I tried everything before removing the shims, now my drivetrain is free and smooth which helps alot.

i have the metal diff gears and LOVE THEM, they shure take a beating

, you know, you can also set your diffs a little loose to also act like slippers

How is the rotating mass. I read that they have some effect on the performance because there's a little more mass to get rolling. Did you notice anything or no?

Really doesn't. It's heavier, sure - but not enough to make much difference. We're talking just a few grams here. Using metal diffs in my rc18r.

They really do stand up to brutal amounts of motor force (not talking mambas).
Can't say anything about wear, since I've not been running the rc18r for that long, and well, being an rc18r, the wheels are smaller, so there's less force too.

rocketrobinnm- I think the metal gears without grease or maintenance will last much longer than the plastic gears. I also suggested that you use the plastic diff gear with the metal input gear. I’m glad to hear you haven’t had a problem with the stock gears. I have had problems with them from day one, using both stock brushed motors and brushless. I properly take care of all of my cars, especially the ones I know to have gear problems.

pinoyboy- You could mess up the shimming on the front and back, so you should buy at least four of them (sarcasm). I’m sure you only need to buy two. If you want to buy an extra, that’s up to you. I’m sure I could easily find 9-10 stripped input gears in my garage. That doesn’t just mean that I have already spent the money I could have used to buy the metal gears, but I know that there have been many races I was unable to finish, and a lot of time spent in the pits fixing the car. I already feel like I am tiptoeing around the track with this car, trying not to strip a gear. The gears should be able to handle some kind of stress from landing jumps and accelerating. This problem should have been fixed with stronger gears or a slipper before it left the Associated's hands.

I haven’t seen a complaint about these gears from someone who does own them, so maybe you should order one and see for yourselves. You could just order a rear pair, $13, since this is where the most stress is. More rotating mass? Good lord, seriously? If you want to argue about it, then I guess you would win; but the last time I checked, you weren’t Adam Drake.

Calvino- Don’t let your diffs slip. You’ll flat spot your balls, melt plastic, etc…

REALLY ???

You "think" they will ?

Metal on metal with no lubrication ?

OK dude, whatever you say

I'm not saying they wont wear, and of coarse you would use lubrication. I'm saying they will last longer than the plastic gears because the plastic gears suck.
