Loving that Motor mount Martin - being three sided it gives optimum support for the motor - mine was made as a simple 'L' shape (like the original 'Halliday' one was) - which under heavy landings off these modern big ramps had a tendency to bend, twisting the plastic gearbox housing in the process
.... a wedge of Lego beneath the motor solved the issue, but its a bit of a bodge Lol!
