MBX6 and LST2 Drive shaft diameter

[Kcaz25]

Now I don't have calipers(its on my list), but i did measure the Mugen ball is around 11.5mm barely larger than the Losi LST that PinkPanda posted.With calipers it could have even been dead on with 10.8mm as PinkPanda posted. I will say it again the LST 2 or XXL is probably what he is talking about because the plain LST will be smaller. Also I failed to measure the hole and the slot.
