First test on gear diff for 1/10 TC

Tested run Photon with rear gear diff today. Installed the gear diff with half-full Kyosho 5,000wt oil. Basic setup and electronics components are similar to last week, except that today is a super hot day here in Singapore.
After 9 packs of runs, no sign of leaking ... yet. The handling is quite similar to ball diff except that I can accelerate even harder when exist corners and overall the car tends to be more stable as well.

I am using Yokomo BD front plastic spool with alloy cover in front. This plastic spool is quite durable as it has been used for quite sometime on my BD and now moving on to my Photon. It is a direct fit replacement to the original plastic spool.

Also tested the Top 044043 insert (firm/thin) on Photon, the same set of insert has been used for 2nd time with Sorex 40R. There are storage of Hara firm insert so we have to find a replacement product. The insert works fine so far under hot weather in Singapore (sunny, dry day) but for super hot weather (hottest day, no rain, no cloud, 1pm-3pm), I prefer either using Tamiya firm insert (black/thin) or go away for lunch break ...
More to test with different setup during next few weeks.
