Hello there! I'm getting my first Kyosho vintage buggy and i have some questions about differential stuff. I've seen that for outdoor and carpet two different diffs should be used: ball for outdoor and gear for carpet.

From what i've seen, to build a gear diff for Optima i need three different packages: OT224B, OT222 and OT256. When i build diff in this way do i need to fill it with any oil? Also, seems like this diff includes only 4 gears: 2 small one and 2 big one. This is because on and old variant? Does this diff enough to race on a carpet? Or it's worth that modern oil diffs? What's the difference? Maybe there is another way to build a gear diff for the Optima Mid?

And with outdoor racing. On which type of the surface i can run ball diff? Can in be used on concrete/grass/asphalt or it only can be used on sand/dirt? Can i, for instance, bring a car to a park with grass/sand surfaces and run it, or diff will be destroyed?

Got to use my new koyosho fazer mk2 wrc for about 5 minutes, until a pebble jammed under the driveshaft and snapped it in 2. I see alot of people say they've never broke a single thing on their fazer and treat em like bashers.. I must have terrible luck.

Hello, i'm looking for an advice in terms of ESC. I want to use Optima Mid 60th on vintage racing so i'm looking for compatible ESC. According to the manual ESC should be 29mm height max. I've checked XeRun XR10 Justock G3S and it's height is 32.1mm. It will not fit? Or fit will be tight? Can someone suggest any other brushless sensored ESC for Optima Mid 60th? Hobbywing also introduced XeRun XR10 Pro G3 with 30.3mm but it still not in the stores i guess.

I’m fixing my dads old kyosho nitro rc car and I can get it running when I pump fuel directly into the carburetor but it’ll die soon after because no fuel is getting sucked up from the tank, I tried sucking the fuel manually which worked so I don’t think anything is plugging the fuel filter, can anyone help me, thanks

Hey team !

I was given a Kyosho Inferno Neo 2.0 and I'm restoring it :)

The original carb has sort of given out and I wanted to replace it with and original part... But no luck finding one.

So I was wandering if any of you guys know of an aftermarket carb that I could slap on there ?

Thinking of selling my RC car stuff from the 80s. How much is it worth? (Estimate without pics? I will post here again once I have them.)

In good condition, comes with kyosho field bag, extra rims, pinion gears, futaba pistol grip radio, extra shell.

Hey all, looking to offload my NIB optima mid. Looking at $360 + shipping. Please PM me if interested. Based in the US.

Thanks

Hey y'all I'm planning out a build using the fw06 nitro Touring Car kit using a bitty designs body. However I've run into an issue with measurements for both parts. The body shell I wanna use is specced at 190mm wide and I can't budge on using a different body. But the fw06 is set at 200mm wide. Does anyone know if a 190mm body would fit/work on the fw06 platform. Or does anyone know of a nitro onroad platform that is 190mm wide that I can use instead of the fw06.

Hello. I bought kyosho krg331 receiver with built in gyro and it doesn't do any gyro... I've read thru instructions. Turned it on and off gain setting etc but It won't work. Another guy said he had the same issue but he got it to work but doesn't remember how just said it wasn't enabled. Any ideas?? Thanks!!

This was given to me by my dad a few years back recently continued building it and tried to look up some info on it but can’t seem to find a thing. I’ve seen a silver model online but nothing about this specific sonax tabac model anyone with a little bit of insight on this would be greatly appreciated I.e. production year, rarity, value?

I recently took apart the diff on this nitro buggy I got used to grease the bevel gear and add diff oil. I felt like everything went into place the right way and ran fine for a couple bash sessions but now I lost all power to the back and see that the drive gear and the bevel/diff gear is completely stripped to the point they don’t really connect. I bought replacements already but I’m stuck wondering what I did wrong? Any one that has familiarity with these I’d appreciate some advice on preventing this

Hey all! I ordered the MK2 chassis kit and realized It is the short Wheelbase FZ02, but I ordered the Chevelle body which needs the long wheelbase FZ02L. Are these the only parts I need to convert to long wheelbase? I didn't want a rtr.. Thanks in advance!

I'm looking at using the new Optima Mid or Turbo body for an old school Maxxum-FF from the late 80's - mainly due to it having the masks and stickers - and the only thing missing is the lexan chassis protector that originally came with the Maxxum.

Does anything like that still exist?
