Thank you for the dumd answer. This is a box stock class for beginners, looking for answers.

The steel universals seem like $50 well spent to replace the front dogbones.
TAM53792 + TAM54477
or just start with a TT02R. The metal dogbones don’t seem to pop at our track.

He asked for some simple trick or workarounds, like maybe a piece of foam or an o-ring, etc. for a box-stock class. Not $50 hop-up parts or a different chassis version (which is also more expensive - not just by kit price, but on top of that the R comes without motor, ESC and body).

For the original question: there's not all that much you can do without spending some serious money (in relation to the normal standard kit price) to move away from strict box stock. Dog bones just suck, and are usually not part of any racing kits any more - for good reason. All I can think of (short of replacing them with universals or even DCJs) is to limit the steering angle on the radio and/or insert some (more) foam or O-rings in the outdrives (make sure it doesn't bind), if that doesn't help, I'm afraid, you only can heed the advice to no longer hit the walls or get everyone to invest in some hop-up parts and leave the strict box-stock idea behind for a strictly limited-tuning class (which is a good idea anyway, since true box stock would not even allow ball bearings on these cheap Tamiya kits - and these are a must IMO).

Yeah there isn't much you can do if you ONLY run dog bones. Limiting steering angle might help. But to loose one during a race is heartbreaking.
We run a class called Production TT02 here. Almost box stock builds.
Only allowed ball bearings, USGT tires, universal joints and some mods that do not improve performance but improves reliability.
My original club allowed esc up to $80. The new club I run allows Hobbywing 1080, LiHV and the high torque servo saver.
I use the Yeah Racing universal joints and cups, as chasing dog bones was SO annoying.

If your rules allow parts other than Tamiya you can buy universals or cvd's from other companies. But, you have to buy the outdrives to match. Someone else gave you the Tamiya part numbers.

TLDR;
Quit hitting things.

Anything for you.

Want to know what helps encourage beginners to get better at driving? Encouraging them to run the middle, so they don't hit walls/rails and inexpensive kits that are easy to work on when they do hit things (which they need to quit doing).

What to know how to encourage people to race? help not troll them and act like your a racing god. Try not being a problem but a solution. Like this

No idea if this could work but maybe limit the side to side movement of the dog bone by having a oring or a sponge insert in the cups keeping the dog bone from sliding into one cup more then the othe and popping. hope this is helpfull

My tt02sr raced in koc gt and now aldershots supersport class holds fastst qualifier at moment shore will go next year when drys up lol

Problem: Hitting things. The dog bones don't fall out under normal use, centered or not.

Solution: Quit hitting things.

troll

Yea but he was probably trolled and hazed when he started. The hobby is filled with folks who elevate their egos at the expense of the newbies. It happens all too frequently. Either get good, get a thicker skin for get the heck out. It's super sad. I remember back in the 90's when you would show up to a track and the vast majority of the racers would talk with you, answer questions and give you pointers on how to improve. Now it's "don't hit stuff". As with just about everything else in life now, it's not the 90's anymore.

well anyone thats know me i will give my time and limited knowledge up. will sort peoples cars that are struggling. alot of the people down Aldershot are the same well most racers i know are like that . Just hate seeing people that are no help talking just being rude, don't have something nice to say then just go your way. Just don't crash is the most stupid answer its like saying just go faster everyone trying to do that anyway also that's not an instant thing and to some not achievable which if that's all they hear is going to drive that person away. But 90s lol yea I was always in my local shops asking sponsored boys what's the best.

Of course that is a solution, but a) not the only one and b) only one for experienced drivers (which you obviously were from day one ...). Problem is, it's not the fitting solution for beginners and even some intermediate drivers. So please stop being so toxic. Just pass on.

100%.

Sorry, but I disagree. I've never seen a track where everyone just jumped up to help (neither 20+ years ago, nor now). Some people did (and do) - but just like here on the forums, those who yell the loudest don't necessarily have the most knowledge and skills. OTOH I have also never seen a track (to this day) where people would not talk to you or help you, if you asked. Things were actually not all that much better (or different) in the past. That's pure nostalgia, IMO. We tend to fondly remember the good things and forget about the bad. Human nature.

Centering the shafts and limiting steering throw will help to a point. Then when the hits become more than "slight", the dog bones will still come out. The next option would be to quit hitting stuff. This option also eliminates the need for the first two options, so why not go there first?
