mbx5t tekno. i need information Daniel

[patxeik]

hi again.
Im finishing the build of my tekno mbx5t, i installed a 15 teeth clutch bell from my revo.
I noticed that the center rear cva have a little elliptical drawing, is like it was a little bend, i noticed that when i spinned the wheels. I wanna know if that is normal since the rear cva is really long, is not a big issue but just wanna know.
Sorry about my little english hope you understand.
thanks


EDIT:
Im testing the mbx5t with the 15 teeth clutch bell of my revo since the 13 teeth stock clutch bell will hit the brake pads and i dont want to dremel it already. But the 15 teeth bell gets really hot, just with a one run (like 40 meters less than half throotle) i can see smoke on the bell, i dont know if the cause is that a 15 teeht bell is a really wide ratio or because the bell is too old and is a little bend. Motor and esc doesnt get hot and i have tried to put the bell very tight with washers and also a little loose just with one washer and happened the same, already i have the bell with 1mm loose
What shall i try now? i have a 16 teeth clutch bell, im going to try and will see if the problem is of the bell.
I forgot to tell that im running 40series tires with half offset because i dont have truggy wheels right now.

Thanks
