    RIP Brian Kinwald...so sad.

    I think I read a while ago that he had Crohn's Disease. Not sure of anything else.

    Outlaw Rampage Pro

    I own the non-pro version of this now, but never had the original vintage. I was intrigued by the chassis design with the solid axle gearbox and motor assembly. Reminded me of a Tamiya Hornet. On tarmac it tilts enough when turning to allow one rear tire to spin like crazy. Extremely plush suspension. If Kyosho sells the option parts separately, I'd probably buy them.

    Kyosho Turbo Optima Re-Release!

    Go for the Turbo Optima. Kyosho needs us to show them that we want them to continue with the vintage re-releases. (plus I want Kyosho to stay in business)

    Lazer ZX restoration finally complete

    Manual: http://www.retromodelisme.com/manuel_page/24/lazer-zx-kyosho.html It's not a convenient PDF, but seems complete.

    Display Stand Options

    I use Plazmost stands for some, Tamiya paint can tops for others. I've also used old wheels/tires stacked up and even old NiCd battery packs. Blocks of wood cut to size would be cheap as well. You can even paint the wood to jazz it up.

    Lazer ZX restoration finally complete

    Hi mrbroons and welcome to TamiyaClub! I bought the reproduction body on eBay from Team Bluegroove. Jonathan's bodies are nice to work with, though the finer details are less pronounced than the original in most cases. I'm not a purist, so I don't care to spend $$$ for an original body. I bought the reproduction decals from marwanrc.com. Marwan is a great guy who also frequents this forum and answers questions from time to time. I've found that dipping decals in soapy water (a few drops of dishwashing/fairy liquid in a bowl of warm water) before application to the body allows you to position it perfectly before it sticks or peel it off again, dip again and retry the application until it's perfect and then press/squeegee out the water to make it stick. Use a hairdryer on warm/hot on curved decals that don't want to stick well. Use a wet toothpick + hair dryer to press decals into tight corners/crevices.
  8. If the Kyosho 240S 19.5T numbers are to be trusted, but the 15.5T ones are not, then how about this: 19.5T: Max Power=280W Efficiency=89% KV=2580 If we take 280W and multiply it by the efficiency, we get 280 x 0.89 = 249.2 W actual working power. (the rest is heat) 2580 KV divided by 249.2 W = 10.35 KV / Watt If we can trust the 15.5T ratings for Max Power and Efficiency, but distrust the KV rating and Max RPM, then: 15.5T: Max Power=320W Efficiency=90% KV=? If we take 320W and multiply it by the efficiency, we get 320 x 0.90 = 288 W actual working power. (the rest is heat) If we assume that the 15.5T motor has the same KV per Watts value as the 19.5T, then: 288 W multiplied by 10.35 KV / W = 2981 KV which yields 22059 RPM at 7.4V Is that more in line with expectations for a 15.5T brushless sensored motor? Note: I'm making a huge assumption that the 15.5T has the same KV/W value as the 19.5T which may not actually be true. But considering both motors are made by the same company with similar efficiencies, it shouldn't be too far off from reality. Unless....the numbers are actually correct, but the 15.5T has way different timing for increased torque compared to the 19.5T. Beats me, I've never used them.

    Kyosho Turbo Optima Re-Release!

    Not that I actually know for sure, but they will most assuredly be one-piece rims. Three-piece is too expensive/complicated these days (screws to hold rims together in 2019?). It will be the same as Optima and Javelin re-re rims.

    Kyosho Turbo Optima Re-Release!

    Awesome! Surprised given the dire financial situation at Kyosho, but extremely pleased. I really hope it sells well. I'll be buying my usual two kits.

    Kyosho Turbo Optima score- easy resto

    Huh, I had no idea Brat tires fit Optima wheels. I feel dumb.

    Schumacher Topcat Re-Release

    U7599 Alloy Front Shock Rocker Conversion - TOP CAT is listed as an option in the manual, but the Schumacher website does not list it and a search comes up empty. Anyone know what the status of it is?
  13. Jim was a good seller and nice guy. Sad to hear. I bought many parts from him over the years.

    Tamiya 47381 - Super Astute (2018)

    6mm?! That will certainly not flex under load. Is that stock or a hop-up item? Edit: Never mind, it's stock after looking at the enlarged photo of the gearbox on TamiyaUSA's site. https://www.tamiyausa.com/shop/-road-buggies/rc-super-astute-2018/

    Tamiya 47381 - Super Astute (2018)

    According to the original manual, the Super Astute used a 20T 0.5mod pinion on the motor, part #3515019. The manual also shows 18T through 23T pinions as options, but no real part numbers. Robinson Racing makes 0.5mod pinions, but they are for a 2mm shaft. What/where do we get spare pinions that fit on a 1/8" motor shaft?
