Gear diffs from Lazer ZX / ZX-Sport

[Pacman]

Does anyone use these Gear diffs in their Kyosho Lazer ZX-R? If so, what grease do you use and any advice on maintenance. I'm building and ZXR but plan to use the gear diffs from a ZX sport for now. I couldn't find any information in the manuals.

A bit of along shot, but instead of oil can you use diff oil in them?

Put in Associated black grease. (Any Hi-Temp Moly grease will work well)
Any diff oil will pour out in seconds and there are no seals to speak of.

Ive used vaseline packed in and am now using grease from nuclear rc as its bloody good stuff but is really down to preference and how free you want it. Also i would suggest finding the hardend drive cup as the standard ones wear out quickly.
