Kyosho Raider (or Outlaw Raider) gearbox problems

[Boons]

Hi all,

My Outlaw (that's on a Raider platform) has an issue in that all the gears spin but the shafts dont, so at a glance it appears the spider gears in the diff are shot. Makes a 'jumping teeth' noise too. To be fair my gearbox is original. I was 'only' running a 23t motor.

Is this a known problem with these cars? I'm now concerned that if I buy a new gear set that it will just do it again.

Cheers!
