Try to avoid long axles made from one piece, especially with such a setup (motor power). But the for the win, get he metal axles........even if they are not so cheap, for such a model they are a must, as you saw :)).

Yeah i thought about using several smaller axles but then you have the weak point on the connections, exactly where i got the issue. The 16L axle is perfectly fine, no twisting nothing, even the side where the extendable cv joint was put on the 3l axle(left on the pic) is fine. But there were 2 screws used.
I mean i did knew that at some point i would need metal axles anyway, cause currently every test drive was only with a 2s lipo, but that setup is made for 3s

I see. Good that you know the problem before it even appeared.
