Wouldn't it be nice if someone at Losi was reading this and it inspired a new production run! I couldn't find any on Ebay - I'm sure a shop mut have one somewhere but finding one could be a long process.
For the fluid maybe an email to Losi would uncover the mystery of what to use - I'm sure they would just have bought some off the shelf stuff which was then re-branded and sold at 10 times the price.
For the science lovers out there here's a link to the patent
