I've found the power stage. But I can't get it out to see how it is heatsinked and how to remove old thermal paste and insert new paste. 10mm headed bolt on top easily removed - but it's still solid. It mounts to a bracket with a bolt to the inner wing and a nut onto a stud on the wheel tub - I MIGHT be able to get at them if I took the battery out. There is a big plug on one edge and that looks as if it should spin out upwards - but with the amount of force I have used so far it does not budge...
