I'm looking for some screws to replace what's missing/incorrect on my car. I couldn't find the hardware listed in their parts lists, or any mention of parts bag numbers in the manual. Can anyone direct me to that info? Thank you!

If you look in the build manual, it will list the size of the screw on the page where those parts are being assembled. If you don't have a manaul, let me know what part you are assembling, I might be able to help you out.

Apologies for not being clear. I'm looking for the part numbers for the BAGS of screws, so I can buy new ones. I couldn't find those in the manuals.

They don't list screw part numbers in the kit manuals. Just check Amain or any other favored hobby vendor. https://www.amainhobbies.com/search?cID=&s=kyosho+screw

You can find lots of 3rd parties selling screws and screw sets if you just search the screw sizes.

On the Kyosho's home page, if you type in the screw size, in their "search" field, that screw will pop up with the part number. For example, type in M3x20, and you will get 1-S33020H as the part number. $3.99 for a pack of 10.

Seems like a better owner than an investment group. Looks like they plan on resurrecting the brand.

i tried to find more info on it, but I couldn't find anything. However I had a feeling this would happen, but not for another year of two. This explains why they dropped their big sponsored drivers. They wanted to reduce the companies overhead to look more lucrative.

If this is real, then it is exciting. A company like A-Too would like to do what they can to stay on top. They are are billion dollar company.

I guess we should be expecting some new buggies within a year or two that will come highly stacked.

When Kyosho runners tell you the gear diff for the the RB7 will leak, believe them.
I had 10 runs before I noticed the car getting squirrely and could trace it to the diff.
It was empty, and my trans gears were well lubed. :/
I have the aluminum diff cover on the way, and will use a sealant for the rebuild.

I had problems with a zx6.6 center diff leaking. I took it apart and used marine grease on the seal and oring and it's been better since. Plastic diff cover.

It will be glorious if they put some serious R&D
into the 1/10 race products. The vehicles arenít that far off current industry standard.
The 1/8 race stuff is already competitive.

The flip side is they could ruin the whole thing.

Fingers crossed for better product support and updated 1/10 race gear.
