All,   Has anyone had experience of fitting cheaper Chinese (£5ish) balance assemblies in this case the 7S26 C variation and been successful?   I went for the cheaper option as the OEM variation seems to be quite difficult to obtain. My experience hasn’t been great, having fitted 4 of the same variation with no luck, for the following reasons:   * 2 x wheels were bent at the pivot, one was so extreme it wouldn’t spin at all, whilst the other wouldn’t regulate due to being out of balance.
