Hi there, I need someone to fix my sons HPI savage x. His slipper clutch cog wasnt working so I replaced this and didnt fit the engine in line properly and I have now stripped the gear coming from the engine. I just need some one with the knowledge to get it all running and check it over and tune it fot him. He has had it since christmas and only used it 3 times with problem after problem. We bought it second hand. I am happy to pay the going rate. Any goid mechanics out there ? I am in HULL, EAST YORKSHIRE
