The obvious solution is to not hit things but that's just not going to happen anytime soon. The worst thng is that the front one broke in the middle of the straight. It obviously had bee weakened before but that's gotta be a hard place to break.
What outdrives, motor and CVDs are you running?

I'm running a stock motor with foams. It's a fairly small tight track. I'm running the stock delrin outdrives. Stock CVD's.

Default Really weak dog bones

I've taken my Hara Edition to the track exactly once. It was an indoor carpet track. I ran a stock motor. I did crash a few times into various PVC walls, but never really hard and no parts broke.

Well, when cleaning up the car tonight I noticed that both front dog bones were bent. I am shocked. I have crashed much harder with a TC4 (composite dog bones) and a Losi JRXS and never bent or broke a dog bone. Actually, I did break one of the TC4 composite dog bones, but I broke it in a huge crash that also broke the hub carrier and suspension arm and bent both screws holding the hub carrier to the "C" bracket. The lesson I took from that incident was crash hard enough and you can break anything.

I am quite disappointed in the HPI dog bones. They appear to be far too fragile. As noted a few pages ago, I won't be going back for more of these parts. I will instead first try the TC4 composite dog bones because I happen to have them in the house. If those don't last, I will go to the TC4 alu bones.

Sadly, I don't have any suggestions. I had read that the HPI screw was weak, but the TC4 screw is supposed to be quite strong. The screws in my TC4 never broke and I crashed into lots of stuff with that car.

Hopefully someone else will have some ideas.

I was running a FT TC4 and I did have a front diff screw break. I did not hit anything. Though could have been weak from other crashes.

I think the one that comes in the Hara kit is stronger. I could be wrong though.

Don't use Composite CVD's in the front 1 or 2 crashes later they will break. Their fine in the rear just check before each run. As far as diff screw breaking, and I quote Barry Baker told me that, "HARA had the same problem so he always ran a aluminum or steel outdrive since it has a better tolerence the diff screw did not break." As far as how true that statement is I don't know but it does make some sense.

Sounds like I will need to make a trip to the hobby shop to get some TC4 alu dog bones ;-)

i use the composite bones with no problems.
but tell me the truth guys....has this car simply dropped off the rc map? i don't see it ANYWHERE! not even at top races. i can count the number of online carpet set-ups on one hand and still have fingers left over! seems to be only two or three big names that USED to have luck with this car and NONE off them were AMERICANS! was this car just a facade so HPI can bank up the $$$$ to push HOT BODIES into the mainstream?
their touring car aint been out a good year yet and already it's more popular than the pro4. i'm sure not long after the new year there'll be twice as many carpet setups. a top competitor here in my state ran a pro4 for ages. he was good and all but he just couldn't keep up until he sold the pro4 and got something else. since then he's be in the top three in numorous more a-finals. even won a few mains! (something he seldom did with the "4"). thoughts....

should i go ahead and dump this chassis or go with the mods i made?(will discuss in a later post). took a long time to get nat's caliber equipment. and every chassis i have is up to the challenge (cept driver ) but the pro is looking a little "un-loved".

rebuttles welcomed.
