Ok. Let me know what you all think about this. I have Supershot, Frog and Wild One renos on the go and have recently purchased diffs for both the Supershot and the Frog. It struck me as i thought about swinging both these diffs into their respective uses that no had one ever bothered with the Wild One in this regard so i experimented. I had to bore out the Wild One gearbox to take the new outdrive bearings and as i had the tool from the Supershot diff set i did this. (The hole saw will not go all the way on one one side, you'll need to flip it and start the original procedure from the outside.) I tried the Frog diff first with a standard Wild One counter gear but the gearbox spacing was wrong so then i tried the Supershot and it worked but there was rub from the pinion side of the counter gear. My solution was to swing in a 49 tooth Frog counter gear and it was as smooth as pie. I haven't run this yet but it will allow the use of the Frog universal shafts too. So provided i haven't sent you all up a certain creek without a certain paddle i'm hoping this may solve diff problems with this model. Apologies, i never mentioned the diffs were MIP.

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.

As per title looking for information on options, hopups and tuning info for the Marui Big Bear. MIP or whoever else. Tried google Found some intel but there is little that got documented. Fotos, Build Info, old instructions highly welcome. Got a v1 myself with mint original gearbox interested if I can still make a runner out of it for a decent price with alternativ parts. thx
