These are the classic Kyosho electric buggies originally designed by Akira Kogawa according to what I could find online (years may be wrong):

Yes, indeed, I saw the same with the Turbo Scorpion and the Javelin. If you have something left, it is because you forgot it during the mount, or that they was a choice within the mount that justifies it. i do not or will not race the Ultima or my Optima just to go out and play a little bit the motors I have are brushed motors and are old but still work they have all been rebuilt many times! From what i have read between brushed and brushless the brushless motors In place of the mini steering servo that was fixed with double-sided tape, the modern version of the ULTIMA uses a servo mount compatible with modern low-profile servos that are popular today. The shape of the servo saver arm has also been changed. Included motor guard (was only available as optional upgrade on the original ULTIMA) is made from A6061T6 material and delivers increased durability. Resin wing mount provides choice of 2 height settings and angle can be set between 3 ° - 6 ° with shims. Previously made from polycarbonate, the resin wing delivers improved crash resistance. In addition to white, there are 5 color options to add extra style to your machine.What with all of the rumours of Kyosho restructuring and the possibility of the Legendary Series being scrapped, I feared that the Turbo Optima would be the last one that we would see.

it is just the internal parts to build the re release trans right??? I am not trying to be a pain about this just clarification pleaseSpecial carbon main chassis with skid angle in the front! New updates for a screw fixture battery holder and servo mount. Plan is to use Kyosho's Le Mans 240S 15.5T 4WD brushless motor and Kyosho's 60 amp ESC, a combo I am already using in a re-release Javelin and a Turbo Scorpion. The Turbo Scorpion has a top speed of over 37mph (60km/h) on 3S Lipo. In wet weather on 2S, it provides a top speed of about 25mph (40km/h). Both re-release buggies are fitted with front and rear sway bars, providing improved cornering. Started to assemble the slipper clutch this morning and I might get the updated pads from the Scorpion. Is an option and seems to make sense with my planed motor setup.

Opened the B bag and prepared the upper rods. 21.50mm is what the manual recommends and I'm pretty close. The only way I'd recommend using anything up to 10T or so brushless motor is with a belt drive conversion and OT-74 limiter gear set (for the Optima), hard final pinion gear in the rear diff and a modern ESC that you can dial down the punch so that the car doesn't have too much torque on acceleration. The punch adjustment functions more or less like a slipper gear. Note that the limiter gear isn't a slipper gear, it just has a beefy spring or a set of spring washers (there are 2 variants) that protect the counter gear from damage while landing jumps. I did all those upgrades with my Barney Optima build and went with an 11T Tacon 3200 kV motor, I wouldn't recommend going any more powerful than that with a vintage Optima or Ultima...and far less than that if you don't do some serious bulletproofing. To celebrate the 60th Anniversary of Kyosho, we announce the release of the 1987 World Championships winning Joel Johnson replica Ultima!This design was so successful that Associated kept it in production for twelve years, making running changes and improvements along the way. This RC10 is a hodgepodge of leftover parts; ten or twelve years ago, I bought two large lots of broken and used RC10s, about ten cars in total, along with boxes of parts. I restored and sold nearly all of them, and built myself three examples using the leftovers, because I don’t really care about originality; I just want to drive them. I fully agree, and as you mention the RC10 versus the (Turbo) Scorpion, I'd like to add that a Scorpion actually won the (rather inofficial) ROAR World Championship against RC10 prototypes/preproduction carss at the Anaheim Convention Center in 1984. The Scorpion was admittedly very heavily modified with aftermarket parts, if I remember correctly, with 1/8 scale Kyosho dampers, Holiday Buggy rear tires on CRP aluminum wheels and a lot of other CRP parts. The gear box UT002 is the same gear box that I currently have in my Ultima and i have a spare gear box I just found in the old parts box so from the list I got from here http://www.kyosho.com/jpn/support/instr ...

I have seen some very nice picture of old Kyosho cars on this forum and that is what I am aiming for with my cars!!! Maybe one day I will get a grandson that is not destructible as my sons were well still are, and I can pass these cars to him one day ULTIMA has been faithfully recreated, with component upgrades for compatibility with modern power sources.The next step was trimming the body and painting the driver in orange from the outside. The Helmet looked too plastic like, due to the inside paint job and I have painted it a second time from the outside. Gear module has been changed to 48-pitch from the original model’s 8-pitch to deliver reduced drive loss. In addition to the newly designed 46 nylon 57T 1st gear, all other gears are upgraded to the sintered metal gears from the OPTIMA. Upgrade with optional diff OTW101 to improve driving feel. https://www.hobbytown.com/castle-creations-sidewinder-3-wp-1-10-esc-motor-combo-5700kv-cse010-0115-06/p618577
