I got to operate my RC car yesterday. It was quite fun. That lasted about 5 minutes, when the front tire came off. 
I have a question about these evil axle shafts and covers. Do I need to super glue these axle shaft covers onto the axle shaft? I think what happened yesterday was that since I didn’t have the top decks on, it might have flexed causing it to break the central differential axle shafts.
I’m surprised I don’t have a current picture of it.
Nice start now you have to find the bugs in the design and make it better.if you ever tire of it I will gladly take it off your hands
As you say, top decks are essential to strength up the whole chassis. I agree that the shafts are weak but I haven’t break any one when are correctly installed. I use ABS (when not Nylon or PC) for these parts. Never PLA.
@bcrazycramer Yes, you need to apply superglue (or similar) between the axle shaft and axle shaft cover for strength. Next car will have a 3Dprinted drivetrain all the way to the wheels so there will be less stuff to buy! And it will be alot beefier for added strength. The downside is you will not be able to fit any standard R/C components.
The same happens to me , they are sliding out , not completely though, must be due to fun driving style I fixed it by using this guis parts. He made a one whole part without covers. Looks great. Perhaps Daniel you should adopt something similar.
I will have to give this a shot tonight. I will get some superglue and test it out. @Daniel_Noree I would be very interested in the Next car!!
I had a blast last night tearing up the parking lot. That lasted about 3 minutes before it shredded the axle shafts that I didn’t have printed with 100% infill. I also broke the drive line. So I took it back inside, replaced those pieces and about another 2-3 minutes and my 100% infilled axle shafts broke.
Got any ideas?
Yes. I have an idea. Print this version of axle shaft. It’s called Strong

What material did you use when printing?
Those wont work for me unless I can get someone to make them 6mm longer. So far, the user hasn’t responded to my request.
I took the Open RC Truggy out for a spin today. So much fun to race across the parking lot. I got attacked by a mob of kids wanting to try it. My rear axle shaft splintered into pieces. Game over. 
Well I have good news and bad news. I got to run my Truggy all over the parking lot last night for about 10 minutes. At least now, my axle shafts are breaking anymore.
Now I’m constantly dealing with a broken drive shaft. Besides just going all metal, do you have any idea what I can do to prevent this?
@bcrazycramer ​ The only material that I’ve had hold up for the driveshafts is Polycarbonate and to some extent Taulman Tritan.
@Daniel_Noree Do you think I would have any luck with the Carbon Fiber? I do have some of that already.
