Thank you. I decided to not convert my lst aftershock to a xxl because i already have the XXL2e. So i have to choose a motor mount wich works for the aftershock. Read some good things about rc monster stuff. So going for that motormount and battery tray. As for single speed hub i went with a new losi hub from lst XXL2e. Complete deal from DollarHobbyz with spur hub slipper.
