Bit of a difficult one really - shame you gave it to your lad to run, seems he may have had a bit of a hefty front-end shunt judging by what looks like a bent chassis tube.... which would mean the chassis maybe a bit out of shape.
Having said that its a team car with all the right bits & RC10s do still seem to fetch decent money..... my advice would be to stick on evilBay & see what you get
