Moth, BigRed and Slowbob you are correct. One o-ring was in pieces and one pin has made a mess of each and every tooth in the transmission. Parts ordered from Microtech and they are not cheap
Not very happy because this was built to the manual. Is the 'fix' to cyanoacrylate the pins in place and the o-ring?
On a separate note, my gear casings do fit rather well but either a stepped joint and/or another screw towards the rear of the casing to better hold the parts together is required in my opinion. The way the B4 casing is designed provides some pointers.
I do love the way the car drives though. Just hope I dont get these problems at EPR (assuming I get my parts by then).
