Default Arcocustom's Kyosho Circuit 1000 Buggy

The nice post lady left this at my doorstep today...











This car is in ridiculously good condition. I had a Kyosho Scorpion in the mid eighties when I was a kid and this one is bringing back all those memories. I feel very fortunate to have found this one. Along with it's excellent condition, it comes already built with a bunch of killer optional parts and upgrades. I'm only a decal sheet and a speed controller away from having one heck of a vintage Kyosho Circuit 1000 Buggy.

Very nice - looks like it was barely run. Loving the trailing arm suspension all around, they just don't do that anymore. Very nice find!

Thanks guys. It's newly built and has never been run. It has a super-rare Thorp diff and pinions, CRP Brass top shaft and universal drive shafts, metal shielded ball bearings, and a few other Kyosho goodies. The suspension on the Circuit 1000 Buggies not only looks great, but it functions great too. These buggies are light as a feather and that helped them dominate R/C racing back in the day.








Here is some great info on one of the best 1/10th scale R/C buggies ever made...

Original catalog ad for the Kyosho Scorpion and Beetle.





At this point I'm thinking the Beetle body would look pretty sweet on the chassis. IDK ??? I am trying to keep it all vintage Kyosho, so I purchased a vintage Kyosho Le Mans Racing Motor today.





It is New-Old-Stock NIP. I found the specs on it and this thing should be fast.

LE MANS 240SB
6.0-8.4v
Ref.# 1924
Type: 540
4 min sprint races
30,000 rpm
19 Turn - 0.65mm x 2
Ball Bearings: 2
Weight: 170 g

Now I need a vintage ESC.....

My first hobby grade R/C was a Scorpion back in the early eighties. My dad bought it used and it came with the giant Brown Futaba box controller that had the Black steering wheel. You know, the one with the throttle control on the right hand side. Those were the days....


Yes, the original owner said it was clean and he wasn't kidding. I opened the box and was very pleased with what I saw. Now I'm just trying to finish it without screwing it up.

I decided to install my old Airtronics FM radio in the car and first up, I needed to button-up the steering. I had to glue the rubber boot to the tub with CA and adjust the steering linkage. I was struggling with mounting the servo and the arm until I figured out the original owner had the steering rod in up-side-down. The instructions are primitive, but after staring at them for a while, I saw what the problem was.





Now I'm ready to mount my servo. On these buggies, the servo gets held in with "Servo Tape" and that's it. This was making me have flashbacks to them early days. Here is my handy work.











That's it for today. Thanks for checking it out.

Thank you Andrew. I do believe we are both on the same continent though...

That sounds like a cool project there Katan. Scorpion+Scorcher=Can't go wrong. I'm sure with your ability, it will be a stunner.

Well, I'm waiting on parts... The motor should be here tomorrow. I did decide on a new lid for this buggy. The Kyosho Beetle.

Kyosho #2138 box art


Graupner #4950 box art

The Kyosho Beetle was an electric buggy based on the original Scorpion platform. With a lexan body in the design of a VW Baja beetle, It seemed to be Kyosho's answer to the Tamiya Sand Scorcher. The Beetle was quite a bit lighter (1,680 grams when it is wholly equipped) and could handle much better than the Sand Scorcher. The body set was not as appealing and had low sales and distribution numbers compared to other models in its class. This makes it very difficult to find one in salvageable condition.

Cox box art


I believe the Cox Scorpion is what my car actually started it's life as. Anyhow, that's what the manual that came with the car is for. I now want to convert it to a Beetle shell. I was able to find a nice reproduction Beetle body from a tamiyaclub member and I now have a complete body "kit" on the way for my roller. Now I just need to decide on how I am going to "decorate" the new shell.

The rolling chassis came with a long list of Kyosho parts that were retrofitted as upgrades, the first of which are the lighter Beetle wheels and tires. The second big upgrade is the shocks. They are Kyosho Gallop MKII front and rear gold shocks. They have been fitted with Kyosho Turbo Scorpion shock collars (dyed Black) and Turbo Scorpion springs. The chassis also came with a new Turbo Scorpion front bumper which is half the size and weight of the original piece. The rest of the car is straight out of the Scorpion box... Yellow tub and all.

Alright, the motor came last Saturday, and I have been busy breaking it in and hardwiring it to my Novak Cyclone. I also installed the receiver so I could test my handy-work.

I soldered a new Novak power capacitor on the ESC, ran all new 14 AWG Novak Super Flex wire, and soldered on a new Deans plug. I soldered the supplied condensers on the Kyosho motor and broke in the brushes using a 4 cell battery. It sounds and looks simple, but trust me, there was a lot of trial fitting and fiddling going on. Let's have a look...




















I bench tested everything and this thing screams. A whole lot of work and not a whole lot to look at... that's the story so far. Thanks for taking a look.
