Last night I was installing the stabilisers on the rear of my BD7 RS. Slight oversight in design by yokomo on the mount holes for rear bulkhead.
First the supplied screws a M3x8. Holes are M2 either a depth less than 4mm. You can't still deeper because you will run into the screw that holds the top and bottom half of the bulkhead together. Needless to say, I had to search for a shorter m3x4 , and hope it holds in a crash.
