scx10 in need of some tlc

[93-12smoke]

So my honcho is in very bad need of some TLC. Since installing my Traxxas brushless system and 2.2 Iroqs I've had nothing but trouble. I've stripped both front and rear gears twice, both sets were the helical cut hd gears, kept striping spur gears and clutches, so went with the metal spur with built in clutch. Now it keeps striping pinion gears but I think this is because the transmission bearings are toasted and the transmission torques and binds.

I'm looking at getting either the Hot Racing HT 61T Steel Extended Outdrive Transmission SCX10 or the axial 2spd transmission. I think rebuilding my transmission again is pointless. Anyone have recommendations on which is better?

Also is there a better axle option out there? I'm pretty sure the cause of the gears trashing is because the plastic housing flexes to much.

[93-12smoke]

Nothing?

[allanon1965]

Which system? Velineon 3500 brushless?

What battery you running? 2s, 3s, etc..

If its the 3500 and 3s you will destroy many plastic parts...you need to beef up the driveline and not be too trigger happy...ease into the power...not instant full throttle...there are a multitude of issues going on there and without all the details...cant tell you much...

[allanon1965]

I personally would run some form of aluminum axle housing...i like vp but they are pricey...grip fab lockers....are you running under drive or over drive gears in the diffs?
How tall are the tires?

[Case182]

Super Shafty bullet proof transmission will solve all your problems. Pricy but you'll never have you replace it ever again.

For replacing the plastic housing.... Go with vanquish. Again, pricy but you'll never have to replace it.

All I can say is aluminum housings for sure will solve your ring and pinion problems. Buy vanquish if you can as I believe they are about the best. If you want more scale go for the curries or the gcm metal heads. As for stripping the pinions I'm a firm believer in 32 pitch pinions and spurs. Robinson racing absolute pinions are the way to go. Now for the trans I'd stay away from the off brand stuff like hot racing or integy and stick with proven brute strength and the bomb proof trans is the answer. If you don't have the cash right now start picking up the parts as you can. Like the vanquish trans case and good bearings all steel internals and some of super shafty or crawler innovations outputs. Just my two cents hope it helps.

Metal trans gears and HD output shafts
Beef tubes for the axle housings
Axial HD front and rear gear sets
Spools to replace the stock lockers
metal drive shafts
32 pitch spur and motor pinion gears.
If you twist or break an axle, then some HD axles front and rear will be needed.

I don't personally recommend aluminum axle housings but if that's what you want that's what your going get.

The SCX10 is not a basher in the sense a rustler or slash would be..They aren't designed to be speed demons and jump ramps and hills.
They are designed for low rpm applications with maybe ocassional speed bursts to get through mud or up a hill.

You most certainly don't need all that power to do what the truck was designed for...I mean who doesn't like power but consider the shape your truck is in now for over powering without upgrades mentioned above.

Hope you get it all worked out.

As far as the axles i'm with 6sharky9 ,Stock housing with beef tubes. IMO the plastic slides much smoother over the rock then aluminum, and with the beef tubes in them they are plenty strong.

[93-12smoke]

I've got MIP drive shafts, upgraded axle shafts, metal knuckles but the gears just won't stay together in the axles. That's what sucks.

I dont really crawl with the truck but it's a scale version of my mud truck. I play in deep mud and hill climb it. That's why I went brushless and my 1.9 boggers were trashed and I spun the centers out of the stock wheels. I replaced them with the 2.2 wheels and Iroqs. The brushless motor gives me the wheel spin I wanted so I don't want to give that up that's for sure.

I'm running a 2s mostly. A 3s sometimes

[allanon1965]

something is wrong here, do you know how the mesh is inside the axle housings? you may need to adjust the pinion gear so it meshs deeper into the ring gear..it shouldnt be chewing up gears on 2s unless the mesh is off...also, what kind of lube are you uising in the diffs?

[93-12smoke]

The mesh feels and looks good. It seems like when it binds or the tires catch it just pops and then grinds. The housings are over three years old and you can tell by looking at them that they are tweeked

[93-12smoke]

Oh, and marine grade bearing grease in the housings

[93-12smoke]

Even the pinion bearings don't really fit tight in the housing anymore

[6sharky9]

You may want to consider some new axle housings and see if that helps you with the bearing fitting like they are supposed to.

If the bearings are fallin out of the housing enough I can see how it would move the pinion to an angle it shouldn't be at because of slop

[WHITE-TRASH]

As you've found scx housings suck unless you're running low power. Step up to anything with real power and you start destroying everything.

Last time I had that issue was the last set of ax/scx housings I ever ran. I traded their fully polished turd asses for a set of AR60's with alloy C hubs and knuckles. Even stock gears will hold up better since the housing doesn't flex as much as the ax/scx versions do.

[93-12smoke]

Yeah, I think the flex is definitely killing them since it's just a pop and they are done. No grinding or anything.

[6sharky9]

Or consider a set of beef tubes to strengthen the axle housings a considerable amount when you get new housings.

[93-12smoke]

First I've heard of beef tubes.

They are metal or aluminum tubes that fit inside your axle housing to eliminate most all flex with them..Just a lower cost alternative to spending for AR60 axles..those are a bit wider than stock axles and don't look so scale .

Its a change people do and what is called a Wroncho build...If you like your tires sticking way out from the fenders then maybe you should check it out.

If you don't then just beef up the stock axles and you wont have anymore problems with them

[6sharky9]

Look in the vendors section and one of them sells the beef tubes to fix your flex problems
