Mark, with the ackerman plate milling you did, are you running the 2L bellcranks, or the original ones?

With Kyosho releasing the TF8, this summer, it looks like they are getting back into racing. That could look a little promising for the 1/10 off road racers.

The guy that made the guards is a UK kyosho driver Steve Bond so might be worth asking him if we will do a few more sets but it was just a small project for him for fun so didnt want to take it full scale
Awesome project this is, quite sure RB7 owners worldwide would be interested in getting a set as well. Pls can you ask him to do more sets?
Thanks.

I'll ask him to see if he wants to make anymore or put the file on line so people can print their own

Yes the UK team are running the milled ackerman bar with the 2l cranks

I wonder too, if drilling a new hole further forward in the knuckle may be an alternative too. Not to weaken the ackerman plate?

Build them and throw them on eBay. I bet you'll sell a few.

There are some setup tips on the Kyosho website. I would also recommend getting the easy access diff case and gear the gear diff. It will also allow you to lower or raise the diff height without raising or lowering the entire gearbox.

I downloaded a set up from Petit. Super complicated lol. For now the box set up was decent, my son was 1 second off the fast lap posted at track.. so not bad for first time out in off-road.

can you post a link to quick diff case? Who makes it?
