help i broke my 410

[jake1*2011]

Hi

i was messing around in the carpark at work and my 410 hit the curb at full throttle(lost sight of it) i drove it back to see the damage and there was bits everywhere

Now the motor is inttermitent, youve got to turn the pinion whilst using the throttle (by the way it hurts) and the spur gear jumps around, it also sounds like theres teeth missing, i also cracked the lipo case, battery holder!

Can anyone help with the motor and spur problem please
