Inspired by guys like Daniel Rowland, and other vintage car fans I met here and elsewhere, and having discovered the extra options the internet gives compared to 25 years ago, when I was running my first cars, I started rebuilding classic RC buggies. At first it was more like getting at least one Optima Mid, as that was my first competition grade car ever, and I remember how impressed I was with it back in the days. But one car just isn't enough, right? So "a couple more" followed over the last year or so. Instead of spreading these over various topics, I think it will be better to just group all together in a single topic.
I've divided this topic into several parts, here's an index: Posting 1: 2WD cars: - Kyosho Triumph - Team Losi JRX2 - Team Associated RC10 Posting 2: Kyosho Optima and Optima Mid: - Turbo Optima - Optima Mid Posting 3: Kyosho Optima Mid and Mid Custom - Optima Mid Custom Special - Optima Mid Custom ZX-R (Lazer/Optima hybrid) Posting 4: Kyosho ??? - Optima Mid (RaceCraft shell) - Kyosho Triumph: I will start with my latest rebuild/refresh, a Kyosho Triumph. As a few of my other cars, it was bought for parts, in this case the golden shocks. But upon closer look, the car impressed me, it had been well cared for, so I opted for a good clean, partial rebuild (front steering and suspension) and a repro body to replace the somewhat battered stock body. It looked like this: ![]() ![]() And now it looks like this: ![]() ![]() ![]() ![]() ![]() ![]() I think it's a "slight" improvement, don't you? ![]() Fully ready to run at the moment, 6 cell 3000 mAh NiMh, Hobby King 45A brushed ESC and same brand receiver, Futaba servo (S3003 I believe) and Trinity "Joel Johnson" motor. Top speed around 35 km/h, car is currently geared for short tracks, so it accelerates like a rocket, considering the mere NiMh battery. Team Losi JRX2: Another 2WD car I had the pleasure of restoring, is this Losi JRX2, which is also present in a different topic here, but is part of the cars I currently have. Before: ![]() and after: ![]() ![]() ![]() No electronics present at the moment, except a motor. Body and wing are reproductions from Team BlueGroove. Team Associated RC10 (runner) One of the most iconic RC buggies is certainly the RC10. I didn't have any past with this car, like with the Optima Mid, but gradually the RC10 started to grow on me. So when the opportunity presented itself to get a runner with some spares, I gave in. ![]() This car came with gold pan chassis, but I replaced that with a black one, to preserve that golden for later. Motor is a Brushed Conrad GZ2000, ESC the X-Car 45A from Hobby King, Conrad 6 cell NiMh pack, and a small but strong digital servo. The first pic does show a different battery pack, but this old and somewhat tired pack was quickly replaced, as it didn't have enough punch, and caused the ESC to go into LVC right at the start of running. ![]() ![]() ![]() ![]() ![]() And here's a short vid of it running: http://vimeo.com/110085792 Last edited by OptimaFan; 07-12-2014 at 09:05 PM. |

My old Turbo Optima already made an appearance in the general picture topic, but it certainly belongs here as well. This is how it looked when I got it:
![]() And with fresh Schumacher tires, some updated electronics and partial refurbishing, including a fresh painted repro classic Optima shell, it looks like this: ![]() ![]() ![]() ![]() Motor is a Technigold, ESC the Hobby King 45A I use a lot for my vintage runners, as it's cheap, reliable, and has very smooth throttle control, also in the low throttle range. Servo is a HCT5010, receiver from HK as well (small and has programmable failsave, so no cars running off if control is lost) and power comes from a 2S stickpack LiPo. It still has the original chain, which took quite some effort to get a couple of malformed chain links, causing the drive to run with "hiccups", back into shape. Luckily I was rewarded with a light and smooth running transmission after that. And this is the car that started my love for Kyosho stuff. Bought as a "vanilla" Optima Mid, it made a profound impression due to the high quality materials used, smoothness of the transmission, ball bearings everywhere, and great looks. After years of driving, it was in need of some spare parts. Also I wanted to reduce slop in the steering, and make the car lighter here and there. Amoung the upgrade parts are alu ball raced C-hubs, ball raced bell cranks, and alu turnbuckles. Also new A-arms were fitted. But after that, I started losing interest in RC, plus I thought the car was now too nice to risk scratching the new and upgraded parts, so it was mothballed. But even without it's stock wing (was damaged during a crash) I think it looks great: ![]() ![]() Btw, it was not my intention to only use the orange band of the stickers that should go in the sides. I just had so much trouble applying the large stickers, and using only one smaller part was the best solution at that moment. |

Here is my first Optima Mid rebuild, a Custom Special, bought as second hand runner. The chassis needed some work, mostly updated electronics, after a glitch during driving made the car run into the sidewalk, which almost cost me a steering knuckle. Also the old silver colored Custom Special body wasn't much of a sight to behold. As in that time I was absolutely convinced I couldn't get acceptable results when I would paint a body, I was happy when Dan offered me to sell a Custom Mid body and matching wing and undertray. And put together, it looked like this:
![]() ![]() Another car, that I haven't presented here before, as far as I know, but one of the cars I am the most proud of. Encouraged by Daniel's "Lazer Mid" I decided to make a "hybrid" as well. Using the complete suspension of a Lazer ZX Sport, that I had lying for spares, including the steering bell cranks, combined with Optima Mid Custom chassis and transmission, hoping to combine the best of both buggies. For body a SWB Optima body was used, but trimmed longer, so it would fit the LWB chassis. ![]() ![]() With wing painted in colors matching the body, and same for the decals: ![]() ![]() ![]() And with wing with custom decals, printed by MCI Racing: ![]() ![]() It's running a Corally 17 double motor, on 6 cell NiMh. HobbyKing 45A ESC and same brand receiver, servo is a HXT5010, basic servo. Body is from Marwan RC, wing is from Team BlueGroove. Strictly speaking it's an Optima Mid Custom ZX Sport, since it doesn't have the turnbuckles, but I do plan to add these in the future, and the ZX-R logo just looks better than "ZX Sport", I think. |

Optima Mid (runner)
I've posted some pics of this one before, when asking for why made the body shell. This is my main Optima Mid runner, just to relive the fond moments I had when driving the white Optima Mid from the 3rd posting. I came with shell painted as boxart, but with the windows painted white as well. Then I got this "graffity-style" RaceCraft shell, and "married" it to this Optima Mid. Also came with stock LeMans 240ST motor fitted, but even on 2S LiPo, it wasn't as zippy as I remembered my first Mid, and that was running NiCads back then. Mind you, those were top NiCads, Sanyo SCRC 1900, matched cells, probably better then average quality NiMh of today. ![]() Anyway, I looked at the brushed motors I had lying around. I didn't want a too strong motor, like an 11 turns high rpm for instance, as this might seriously reduce lifespan of the gears, and may also need additional cooling, as the secluded motor position of the Mid doesn't allow for much airflow over the motor. My eyes fell on a GM Racing Purple Beast 15 turns. It seemed to run a fair bit faster than the LeMans 240ST, and has good airflow through the car. I dropped a tooth on the pinion, from 20T to 19T, and gave it a go. Now the car was more like it. More wheelspin if accelerating hard, and better top end. Previously it clocked in at about 37 km/h at most, now it was almost 44 km/h top speed. For a better comparison, check the vids listed here below: http://vimeo.com/110719347 (stock motor) http://vimeo.com/110715841 (GM motor) (Reserved for some more cars) Last edited by OptimaFan; 07-12-2014 at 05:49 PM. |

Very nice Turbo Optima. I really like the paint scheme.
