3Jean 1 Posted September 6, 2020 Good morning all, So I just got my first Kyosho kit, a Turbo Optima Gold and I'm really looking for ward to building it! I think I have all the bits I need, but I have a question about the silicone oil for the diffs. The manual says it can take 5k to 30k weight and I have some 30k and 50k Traxxas fluid. What are other folks using for the front and rear diffs on this thing? I won't be racing it, just blasting around my yard and the street (and maybe the beach too). Any suggestions most appreciated!

Mrowka 494 Posted September 6, 2020 I have 15K in the rear of one of my Javelins and 10K in the front. FWIW, it's pretty squirelly. Same basic chassis as a Turbo Optima. Share this post Link to post Share on other sites
3Jean 1 Posted September 9, 2020 Thanks Mrowka, I got some 5k and 10k so we'll see how it goes. Share this post Link to post Share on other sites
Mrowka 494 Posted September 9, 2020 There's some other threads out there on how differential fluid affects handling. Because it is a pain to remove the differentials, I would think long and hard about how you want your car to handle and what fluid to use in which differential.
