If you've never broken any Tc3 front arms racing them on a track (as opposed to bashing in an open parking lot for instance), you haven't tried hard enough! (or you're a darn good driver...)

Life is short. Waste it wisely.
Aluminum screws will shear (as scr8p said, 'specially with aluminum rear mounts), and the nylon rear arm mounts break, even worse so on the 10T than the 10, as the big tires and added weight, and longer arms give added leverage to breakage.
I'm a fan of using the Titanium screw kit from Lundsford (for RC10GT), but some think that Titanium screws can break. I've broken Titanium tie-rods, but not a chassis screw.
The two older styles of stock tie-rods (plain threaded rod & threaded rod w/hexes) are known for bending and breaking rather easily.
I thought losi eventually used larger (5-40) diameter tie rods on their kits, but to do so on an RC10 or 10T could result in cramped space for the larger ball ends, behind the front bulkhead, against the bellcranks.
Stock hinge pins bend, and the titanium ones can be brittle (just ask lowrydesign)
Speaking of hinge pins, the RC10/10T weren't designed with captive hinge pins, so the e-clips are always falling off or getting mutilated. old motor shims and shock o-rings help with that. Old designs like the RC10/10T didn't have set screws locking the hinge pins in place on the arm mounts either, but then this feature can be retrofitted to older parts.
If you're using brushless, the idler on the stealth tranny is very weak, and the next weakest link is the diff gear. The heat just mutilates them. Actually, the diff gear is tied for weakness with the stock and upgraded single disc slipper setups, which burn up the discs unless nearly locked-up. The Robinson racing keyed slipper upgrade or the T4 dual slipper is the way to go there.
The pinion to spur mesh is very vulnerable due to the poor sealing of the gear cover, which has a tough job due to wear from larger spur gears, and from uneven sealing along the boundaries of the (small) motor plate it attaches to, which both conspire to allow ingress of dirt and debris.
Don't forget that the motor plate itself is weak and is prone to bending whilst bashing & running hard (see below for: chassis).
Of course we can't forget the chassis, which although strong, will need to be shot-bagged and/or malloted for straightening and re-conditioning after much bashing and hard running. Lowrydesign has done this so many times, he could design a custom anvil just for doing this. You will need good dead-blow hammers, metal (copper?) hammers, and a straight edge at the least.
Oh and don't forget to maintain all the ball bearings, especially on the wheels, hubs, and the outdrives. They get thrashed from bashing and hard running.

I broke mainly tie-rods and had an issue with the stock servo saver locking up when hitting something. I remember breaking suspension mounts and a fiberglass shock tower, but those were either in really cold conditions and would snap or after I had dyed them and they became softer so that the parts actually ripped instead of snapping a clean break. I remember when we were racing outdoors people would keep their cars warm on really cold days by sitting them on a generator or leaving them in a heated car to avoid the cold/brittle breaks.
i guess if your entire goal is to beat the living piss out of your car, ya.......... your gonna break alot of crap. but under normal race conditions, the cars are pretty much bulletproof.
only thing I've ever broken is the front shock tower and a lower shock mount. And while I haven't beaten the living piss out of mine, I did get it to slide about a 100 feet on it's lid

The only thing I ever "broke" on my rc10 was pulling the bottom shock eyelet off, and popping ballends off. And I jumped my car into that damn brick column at the VONATS last year, no breakage from that crash, but man was it embarrassing

Aaaaahhhh crap! I'm about to get passed by that orange truck!

Why you braggin, maybe its the radios fault???
Well I didn't mention the melted diff and shredded idler gear... But I blame that on me. 9000kv motor, 2s lipo and doughnuts in the dirt I learned my lesson the hard way

I never would have guessed that the spiked tires would have worked! Way BITD we had a clay D/O track local and guys would take regular foam onroad tires and "cap" them with clear RTV silicone. It was the hot ticket. I couldn't find clear once so I used white. You should have seen the looks at the track I got that day. Guys made special machines to apply the RTV evenly and then balanced all them. It was a science.

Well I guess I spoke too soon
Today I Cracked a front A-arm, Bent a rear turn-buckle and broke a new rear shock tower
Alright just like last year when we had snow, I find myself wanting a Kyosho Blizzard ...... bad. We're getting 10 inches of snow today and I find myself watching Blizzard videos on youtube marveling at how well these things go.
It seems like this...

hey guys, recently bought a the new SR, already took the motor and esc out. I am looking to go brushless with dual traxxas blue veileron motors, anyone recommend a good dual motor esc?
Well, after a weekend of doing important stuff, cleaning, painting, bike riding, etc, I decided to finally take my runner out for it's first real run. I built it up this winter. It's a totally loaded gold tub with a 14T Speed Gems motor and a Super...
So I bought a used savox servo on rctech and although it dies work, it's a little weak compared to the other 3 savox I have, despite being more powerful and faster on paper.
I tried it in all 3 of my cars just to see and there was no difference....

Thx, I ended up prying off the middle gear first with a screwdriver and got the gears off but then got stuck with getting the rest off so I gave up and put it back together. Weird thing is it seems fine now. Oh well, put it in and drove around...

SWEET RIDES MAN !!!!! I had the Sandy experience also but luckily never lost power....
Hello, I just got into the RC10s and was wondering if someone could tell me why these two front-ends are different. Which one is older, better, etc... THanks!!!
can ppl please post any pics of rc10s from bitd that were iconic in the racing scene??? i would really like to see them and maybe a little info at least drivers names... i need motivation to build a few of my 10s. thanks everyone

thanks scr8p its your cliff lett car that makes me want to try this plus i was hoping for a bunch of classic race cars to pop up so we can all come here for inspiration lol
