  1. OK! I have the one RX-7 body parts set I need, so I don't know if it's now hard to find, but Seidel has the body and sticker set in stock. A suitable chassis isn't hard to find. I guess you would want either the M06L as included in the RX-7 kit or the newer M08L. If sourcing the kit, or the body and a chassis should turn out to be difficult, I will happily help. At no additional cost, of course.
  2. Do you need the kit, or would a separate body parts set and a suitable chassis (M06L / M08L) be adequate?
  3. Of course I don't know anything about Tamiya's or MRC's (back then) logistics, but as you also indicate, the Grasshopper sold very well. Also, (storage) space is expensive in Japan, so I think it's rather likely that Tamiya, MRC and US hobbyshops had depleted their stocks of initial production Grasshoppers long before you got your Grasshopper in 1986. I generally don't support the conception that allows a Tamiya model to be clearly categorized as Mk. I, Mk. II etc. depending on when they were manufactured in the model's production lifespan. After all, rather than having distinct irreversible break points, Tamiya generally tends to do running changes, which sometimes aren't even in chronological order. With this in mind, I reckon that there may have existed more than one variation of each that can be referred to as "initial" and "early" production Grasshopper. Furthermore, I reckon that if Tamiya for some reason had Grasshopper tubs in stock after principally having replaced it with Hornet tubs in the Grasshopper kit and after the release of the Hornet tub as the spare part for both the Grasshopper and Hornet, there's really only two things they could have done with them; 1. scrap them or 2. include them in Grasshopper kits, of which option 2 makes by far the most sense in my humble opinion. So, as your Grasshopper came with a 6V connector, resistor cage and Grasshopper tub, it seems pretty clear that your kit wasn't from initial production, but probably of early early production and that MRC and/or the shop had it in stock for an unusual long time before you got it. I don't remember when the MSC in the Grasshopper kit got the 7.2V connector, BEC plug and bullet connectors, but probably a bit later than 1986. If I recall correctly, the colour changes of the MSC and resistor plate happened even later. I wonder how many different versions of the Grasshopper kit that ever existed, not counting the re-re? Definitely more than three.
  4. I don't know how long the site have existed, so it may be well known to those of you with a special interest in the FAV already, but I guess sharing doesn't hurt. I stumbled over this site yesterday: http://www.fastattackvehicle.com It's full of information about the FAV from early to late history, including how it came to exist. It also covers how inadequate the FAV actually was for the tasks it was intended for, so unless you already know, you may be up for a disappointment! A couple of appetizers; 1. FAV as used by the US Forest Service, 2. FAV dropped from 100 feet by a Blackhawk, 3. 20 first production vehicles as delivered by Chenowth.
  5. About 75 EUR anodized silver or black and 84 EUR anodized blue. (Edit: I just noticed that despite shipping included, actual price varies with the buyer's location. So, between 75 and 100 Euro is seemingly the more appropriate answer.) Auction links: Black and silver Blue
  6. I apologise if this topic has been covered in the forum already. The aluminium chassis for the Wild One offered by Aidong RC has been available for some time, but yesterday I stumbled over their new "Blockhead" version, and my already existing urge to know other fans' opinions was revived. I haven't seen any photos of the chassis actually fitted with all the needed Tamiya parts, so I can't say anything about fit or durability, but judging by the photos, the manufacturing quality is high. Also, a lot of considerations and technically qualified thoughts have obviously been put into the design. Or in other short words; the chassis seems to be pretty good! What I wonder however, is if it's not a missed opportunity? I mean, the original chassis has ample flaws and back in the mid/late 80's, I'm confident that an aluminium aftermarket chassis would have sold pretty well. Being released pretty much at the same time as the Fox, the Wild One wasn't chosen for racing by many, but a robust and well designed aluminium chassis would have been attractive anyway. But what about now? If I was to specify an aftermarket chassis for the Wild One just for my own preferences, I would have wanted it to get rid of the flaws of the original of course, but the most important feature would have been scale looks. Also, I wouldn't have wanted it to have all the openings of the Aidong chassis, as I prefer to run the Wild One on loose surfaces and would want the chassis to keep debris out. What do you think? Has Aidong nailed it, or is it a missed opportunity because of the "racing" rather than scale design? Btw, the chassis is available in black and silver anodized too.
  7. I realise that my reply is very late and you and other ATC owners who have looked for repro stickers probably know already, but anyway; MCI now offers repro stickers for the ATC and it's not because of my effort. I started scanning and photoshopping my used original stickers about two years ago, but never finished, I'm embarrassed to admit. Anyway, I bought MCI's stickers and though I haven't used them yet, a comparison with the originals and knowing MCI's general quality, they seem fine. Also, Kamtec now offers a repro body, which I bought yesterday after getting another ATC without body. Kamtec's body looks good in the auction photos, but as the original body is a tight fit over the chassis, the dimensions of the repro are absolutely crucial and I'm excited to see if Kamtec has nailed it. The front number plate seems to not be included with the Kamtec body, but it's easily enough to cut and bend from ABS stock anyway, so no worries.

  8. Yes, they are just sprayed, probably decades ago. The auction included several more photos and in one of them, it's visible how nuts and screws also have been sprayed. I need to replace them with unused original wheels I have. The model hasn't arrived yet, but I've already dug out the parts that can be identified as missing from the auction photos. I'm also excited to get the included initial production Grasshopper manual. I didn't care to get one "back then" and it's one of relatively few manuals I don't have.
  9. The colour(s) you've used shouldn't by chance be fluorescent? Tamiya's PS fluorescent colours tend to flake quite much easier than the "normal" colours. As a matter of fact, I have tried a lot, but haven't found any method to make the fluorescent colours stick equally well as the other colours.
  10. Exactly. Initial production Grasshopper came without connector, early production got the 6V connector and late production the 7.2V connector. Similarly; initial production Grasshopper wihout resistor cage, early production with resistor cage as a separate part mounted with a screw to the resistor plate, late production with installed cage held with folded tabs.
  11. Yes, but that was changed to white relatively late. I don't remember when the change happened, but unlike many of the changes mentioned by you and me, also later (than initial) production Grasshoppers came with black ball connectors.
  12. I intend to make a comparison with the later production original release Grasshopper as soon as I receive the one I bought tonight. To be honest, I don't think I can list all differences from the top of my head.However, but a few are easy: 1. When the Grasshopper was first released, the Hornet was still in the pipeline, so the initial production Grasshopper has chassis tub marked "Off Roader" and not "Hornet", and doesn't have the hole for the front body post. The Grasshopper/Off Roader chassis tub as a spare part was available for only a short time, being replaced by the Hornet chassis tub for both the Grasshopper and Hornet. Initial production Grasshoppers that have survived typically have had the original tub replaced with a Hornet tub decades ago. Original tubs in good or like new condition are very rare. 2. The initial production Grasshopper was prone to broken "axle tubes"; ie. the axle tubes would break off from the gear box pretty easily. Tamiya improved the design for later production. 3. For some reason I still can't imagine, the initial production Grasshopper came without battery connector on the MSC. The buyer thus had the choice between 6V and 7.2V connector explained in the manual, but as the typical Grasshopper buyer would be a novice, I honestly think it was pretty stupid to leave the task of fitting a connector to the buyer. 4. The initial AND early production Grasshopper came without bullet connectors for the motor and MSC. 5. Intial production Grasshopper came without protective "cage" for the resistor. 6. A change that was made relatively late was including a 850 bronze bushing for the spur gear as the initial (and early?) use of the black 850 plastic bushing caused many ruined gear boxes. I can't remember exactly when that change was made, but I clearly remember the bronze bushing being provided in a separate plastic bag (in the kit) with a small instruction sheet explaining how to use the bronze bushing instead of the plastic bushing as according to the manual. In the later revised manual, the bronze bushing is covered. Also, the part itself was packed with other parts and not separately. 7. Initial AND early production Grasshopper MSC's included a fuse. Later omitted. I've probably forgotten a few details.
  13. I guess some "professional" first aid kits may have high quality scissors included, but surgical scissors are of a much higher quality than any scissors I've ever seen in first aid kits. One of my my ex girlfriends is a veterinarian and during our relationship, she gave me some surgical scissors after I had complained about how quickly the relatively expensive Tamiya decal scissors would wear out. At 2-300 Euro, I would never have bought scissors like that, but after using them for some time, I realized that they are worth it. I've mostly cut lexan and stickers with them and haven't been careful, and after 10+ years, they are still virtually like new. Highly recommended!
  14. I used to have a big interest in aviation, including collecting models. So, I've had some basic knowledge about the names of Japanese planes from the World War 2 era for quite some years. Names like Kikka (orange blossom), Ohka (cherry blossom), Shusui (swinging/sharp sword), Shinden (magnificent lightning), Shiden (Violet Lightning) and a couple of others are pretty well known. Tonight I stumbled over the Ki-201 Karyu, the successor of the Nakajima Kikka. Karyu => Fire Dragon! So, is there a connection between the names of Japanese planes and names of (some) Tamiya buggies? I simply had to dig deeper. Well, what about the Nakajima Ki-49 Donryu => Storm Dragon (suddenly the name change from Super Dragon to Super Storm Dragon doesn't seem so stupid after all!) Or Aichi B7A Ryusei => Shooting Star Or Mitsubishi Ki-21 Rairyu => Thunder Dragon Haven't found any Thunder Shot or Saint Dragon among the planes though. The ORIGINAL Fire Dragon and Storm Dragon:
  15. Won an auction tonight for a never completed and obviously never run Grasshopper, but it's incomplete and the stickers poorly applied on an unpainted body. Who cares?!?! It's an initial production Grasshopper with all the small peculiarities and flaws that were corrected after just a couple of months after release! And I paid less than half the price of a re-re for it. I feel lucky!
