They were all Fred and Justin's parts but the castor blocks were about a 1/16 of an inch wider than the arm opening. You may have gotten an earlier revision and not the final versions. People started buying more parts so I've taken them down. Everything should fit just fine. Once I get my car done ...

The belt is an XL profile, 1/4" wide, 25 groove.

I have a set of each. They are great. Orange should be available this week.

I know this is an old thread but I've finally got an answer for it! The belt is an XL profile, 1/4" wide, 25 tooth.

EDIt: Nevermind. Found it.

Hi guys! Bit late to the table here... but is it possible to buy a kit? (chassis also) I actually got hold of an original ARP kit on ebay/US but I sold it on to my friend LurkingCAT who has been dreaming about one for ages. Now however I'd like to race with a clone :mrgreen: I think I only made 8 o...

Was it the Kyosho Rowdy Baja Circuit 20?

Here's another.

I've got several pictures of the 89 car. Here's an early version that they used to develop the 91 front end. They merely reversed the 89 arms at first and started reworking from there.

The 89 chassis is actually longer.

I've never modeled the shocks or a body so I haven't been able to compare a few things. I honestly don't think I'm good enough to model the body. I'm really more of a design and mechanical engineering based person and not an artistic or rendering based one. Years ago, Curtis had given us the wheelba...

Very cool to see someone else tackle this car in cad. Yours looks great. The wheelbase on my version when all arms are level is 11.125". Curtis gave us the exact length on the top deck so we know it's right. The rest of the wheelbase really comes down to interpretation of the arms. I still have...

there is a gentleman (Fred Baumgartner‎) on facebook that is injection molding in his basement with very nice looking results- cant wait to hear how testing goes. I saw that. They look nice. Until they are tested, we have no idea if they are durable or not. Fortunately, he has the ability to do som...

3D printing costs more to the end user as they are paying more for each part. It saves the designer the tooling cost but at the expense of profit. Whereas a $0.20 part could easily be marked up to $3.50 with a molded part, that profit initially goes towards repaying the tooling costs which were paid...

Sales would really only need to top around 600 cars or so to break even on tooling. The 9500 number was based on selling them for cost, or only $0.19 each. With a markup to around $7 per pair and family molds, the number comes down significantly. The large manufacturers will fulfill that number with...
