hmmm... Sloppy and weak. Not sure what you mean by sloppy. And I havent been able to break one and I have broken just about everthing in the drive line of my revo.
I'm actually using 23mm on the revo now just because my truggy (cen) uses 23mm hex and then I can swap wheels back and forth.
If you really want red, Integy makes a red 23mm hex for the revo. You would just have to go to to 23mm wheels instead of 17. Not sure if the Intgey are any good or not, but they are red.
