This is what I found inside my MO5 V2 after race night the other week on low grip asphalt. There was also a small pebble wedged in the teeth of the TOP Sabre FWD oil gear diff, but it was salvageable. I have since blocked all ingress points and will see how successful I am.
I am also using this body at one of our large tracks and found it to push a little but still gave me my fastest laps.
Will put some other photos up also.
