I wanted to fit a QR directly to the motor shaft, so have removed the SC2 QR male portion and fitted one of these plates: https://www.simracingmachines.com/WebShop/srm-qr-adapter-for-sc2-wheel-base
When I attach the Q1R wheel side connector, it leaves some small gaps around the edge that lead to the internal sliver part of the drive hub, which were previously completely covered by the SC2 QR part. (see pic).
A question for the SC2 team @Mika Do I need to cover these small holes or is it ok to leave them? I imagine a tiny bit of dust could get in there over a long period of time. Many thanks
