I think some people forget where we sit in this relationship. For any large RC business racers are a tiny, tiny market. We are surrounded by microscopic companies that rely desperately on us racers and forget that actually the vast majority of RC's never see a track.

Hobbyking won't submit Turnigy lipos because they don't want to be the official importers. Whilst they are the main source for them they aren't exclusive and most other sources aren't in the UK. Technically they aren't liable for anything not sold through their UK warehouse (even their own overseas stuff doesn't count) but proving where it came from could be hard. Since they sell plenty of packs as it is, going for approval will probably cost them more money than they make in extra sales.
After all racing is a tiny part of their business. Hell lipos for cars (racing or not) is a very small fraction full stop!
