Isn't that part of the reason the harder/stiffer front arms (and rears) were released? If the carbon inserts really were required, after 4 years on sale (or had the MP9 been out for even longer than that now?) and winning multiples of national and world titles, don't you think someone would have done it by now?

I didn't see how Cody broke an arm at the warmups but considering he won his WC with the original front arms (and rears too I'm pretty sure) and Tebo et al have been able to get through their 60min races without a rash of arms breaking, I am thinking this seems to indicate that there really isn't too much at all wrong with the current parts.

Just my $0.02 but I reckon the results speak for themselves.

And, yes, I did see the pics with the HB arms and carbon inserts a couple pages back.

Spur gear is the only issue I've seen in 3years. Arms are fine IMO. But then again, my local track is pretty brutal with huge jumps, on most tracks I never have any issues. I'd like to see the car with a tougher spur gear. The surface area is really small where it comes into contact with the clutchbell. And yes, I know, I've read all the methods for prevention, so no need to bring them up again.

I am making the switch from TLR to kyosho (now looking at a brand new 3.0 roller I won't use). I bought a very clean TKI3 with tons of spares from another member. I am wanting to do the D812 arm conversion on the TKI3. The rear arm should be a simple swap. However, does anyone know if the kyosho knuckles and spindles will work on the D812 arms? What about CVD length?

Any info would be greatly appreciated.

I will add this viewpoint- I have and race the MP9 and D812. I know for a fact the arms on the D812 are more durable and less prone to breakage which also saves the hinge pins and pills. I think the carbon inserts stiffen the arm as a tuning aid for responsiveness, not durability. If i'm not mistaken Tessmann runs the kit plastic inserts in the front arms and carbon rears most of the time for that reason. I think the hard Kyosho arms are to compensate for stock arms getting "rubbery" in hot weather, and would be too brittle in cooler weather. That last part about the hard k arms is just my suspicion as I have not tried them. Kyosho arms don't get sloppy as quickly as the Hot Bodies arms do. I think the only times I've broken an MP9 arm was from clipping a non movable object. .. wall, peg for piping, bush precariously close to back side triple and one freak landing. When it's 40f all bets are off as the stock arms are waaay brittle. Otherwise, cartwheeling and various other forms of improper driving aren't a big deal.

I also don't think those kinds of tuning aids are necessary on the Kyosho. Plus, I found on my d812 that the super flexy suspension caused me drive shaft problems-bent with NO wreck. While I think the d812 is a good car, I would in no way ever think that putting the front and rear suspension on an mp9 would be an upgrade. Guys will do what they want, but that's my 3 cents.

K car doesn't need stuff like that, I rarely need to make major changes from track to track, Find that base set-up that works on most tracks and change small stuff but not much, gives you time to focus on your driving
