What do I have to pay attention to when assembling oil-filled differentials to ensure that they are really leak-proof? I have the feeling that about every third differential I build is leaking. What could I do better? Less oil? Thicker oil? I would be very grateful for some tips. 🙂 What are your experiences and recommendations?

If I see it correctly, the following Tamiya silicone differential oils are currently available: Vis. 2k, 3k, 4k, 5k Vis. 100k, 300k, 500k, 1000k I learned that the higher the number, the less fluid the oil is. However, the big difference between 5.000 and 100.000 surprises me. Which Tamiya silicone differential oils have a medium viscosity?

Back in 2012, the world was a different place. For starters, I did not have a Tamiya Striker - until late in the year: Apparently, I had a hankering for something very different, and the Striker was unlike many things before or since. The "sharp wind-cheating Formula 1-style body" [- Tamiya promotional video] and the desire to "hit the trail and strike out the competition" [- also the Tamiya promotional video] led me to acquire one. It was put together during my time in post-secondary school, which meant minimal effort to get it going. The only chassis modification I made at the time was adding the Team CRP front chassis brace and bumper set for the Futaba FX-10. Stickers, different tires, and a painted helmet were all I needed to "enjoy" the Striker experience. I ran that car for two years, after which its run time became sporadic (I even half-heartedly listed it for sale in 2016), to be resurrected in 2021. For all that time, the car retained its controversial front swing-axle suspension. Accompanied by a heavily rear-biased weight distribution and pure friction dampers, the understeer was very tangible. Initially, I accepted it as part of driving a Tamiya Striker, but over time, the intrigue of a double-wishbone conversion at the front end lingered. The time finally arrived when I pushed the Striker a bit too hard and broke both front suspension arms: My wallet made the decision for me to finally abandon the stock front suspension setup: not only were front suspension arms scarce, but they were expensive! It was cheaper to attempt modifications than to shell out for NOS parts, and so the trials of customization and testing commenced. The first iteration used Grasshopper II parts: Citing similarities between the Striker and Grasshopper II, I came to learn that about the only front-end components those two models had in common were wheels and tires. I did manage to make it functional, if not entirely useful... And so begins the modification of a humble Tamiya Striker!

So I've just purchased a nearly new Madcap that's only been run a couple of times indoors. Just wondering what's the hotest motor I can put in it without risking the diff, and what other sensible mods would you advise. It will mainly be a shelfer with a bit of light use. Thanks

Any commercially available sealed gear diffs for WR02? Any that will fit, with or without modification? Anyone try sealing a stock one with gasket sealer or anything? (I started a couple of these as an experiment, project interrupted- will share results) How about a real spool? (not locked) Thanks in advance

Hey All Some of you may have seen my eBay listing for this item but i figured i would try to sell it on the forum as well. I have been parting out my ORV related items to fund other builds. Up for sale is a great package for someone with a Re-release Frog or Brat or Vintage Frog, Brat, Monster Beetle, or Blackfoot. Selling a very lightly used MIP Ball differential that has less that 3 runs on it! These Ball diffs only began selling at the start of this year. You will get: - Assembled MIP Tamiya Super ball Diff Part Number: #16210 - Remaining MIP Ball diff grease - Tamiya ORV Gearbox with all mounting and closure screws - 16 Tooth pinion with set screw and matching spur gear - Tamiya gearbox pinon gear cover with screws - Assembled Tamiya Universal Shaft Kit Part Number 53908 (dog bone ends are in the boot so you cannot see them in the picture) - Tamiya rear axle shaft joint boots - Tamiya rear plastic hubs with drive pins The re-release Monster Beetle and Blackfoot now come with the universal shaft kit. The re-release Frog and Brat need the universal shaft kit to take advantage of the MIP Ball differential. If you have a Re-release Frog or Brat or any vintage Frog, Brat, Monster Beetle, or Blackfoot, this would be everything you'd need to take advantage of this new ball differential setup. Price is $105 PayPal'd and shipped to the US.

Hi everyone, quick question... I have a brand new striker gear bag but its missing the differential spur gear (the part that the 3 small bevel gears go into) Apart from the sonic fighter and falcon, is there any models which share the exact same part? There are plenty of hornet, wild willy and lunchbox gear bags about, could I used just this part from these sets????? Thanks!

I was wondering if there's any upgrades to the gearbox on the SRB that would make it stronger?
