    The Lancia 037, too. You can message me if you happen to like Lancia-related nonsense, spam, and/or tangents...

    You can also message me if you want to share your RC concepts or projects. Most of the time, the only thing I can contribute is a listener, but I still enjoy hearing about new ideas!

  1. ... Well, there goes my attempt at Round 30: https://imgur.com/a/nFwkQnq If the 1:1 cars can't drive safely, the 1:10 cars stay parked... ... unless I manage to take out the Bruiser before the deadline
  2. Nice find! I like the provision for a centrally-mounted steering servo, but it looks less obvious if it will fit the ORV's original torsion-bar suspension with internal coil spring. Just when we thought the Frog couldn't get tougher...
  3. An intriguing proposition... ... However, I thought the F104 wheelbase was 270 mm. The GT-One and F103-based cars had a wheelbase of 260 mm. It could be easy enough to cut new wheel arches, though, to make up the 10 mm difference (that is, if I recall correctly). Basing it on the F104 might mean better handling, too... I have been on the lookout for GT-One shells, and they do tend to cost more than a complete kit these days (it's all greed at this point...). At least they are around, though, which is a good thing.
  4. Go for it! What I went for today was a motor swap; my pinion puller finally arrived, so I was at last able to remove the stock motor from the chassis. What replaced it? Having realized that the chassis and Tamiya Mini 4WD cars both use 130-size motors, it was impossible to resist! However, I did need to drill and tap two screw holes for mounting the motor to the chassis: I soldered the wires myself, having found the appropriate connection for the motor to the ESC-receiver combination. I made a slight modification by removing part of the motor mount to fit a small heat-sink, even though installing it would cover up the motor decal: My choice of motor was actually quite conservative; I arrived at the Hyper-Dash 3 after comparing advertised RPMs and torque across each of Tamiya's Mini 4WD single-shaft motors. Of them, the Hyper-Dash 3 offered a few more RPMs and similar torque to a standard 130 motor, which I felt would be a decent upgrade without making the car uncontrollable. Of course, with the experience of installing one motor, I now know what to do should I find myself wanting more power We will see how it runs with the Tamiya motor!
  5. This looks like a challenge! Looking forward to putting tires to pavement for this one
  6. I had the exact same model; it was my first Tamiya. As junkmunki mentioned, it seems that the MSC parts were standard-issue for the F103RS and RX, possibly to add value/lower costs relative to the other F103 chassis of that period. The chassis from the listing looks like the F103RS; the F103LM's wider plate allowed the steering servo to be mounted on its side. I would figure that it is about as valuable as any used F103, whatever that price may be (I personally have no idea what an example might fetch on the open market).
  7. Any pictures of the underside? That otherwise looks like a standard F103 with the mechanical speed control tray installed (without said mechanical speed control). It would be easier to determine if the shape is that of the chassis plate itself or any sub-assemblies if we can get another angle, please.
  8. Wow! Congratulations to our podium @Andreas W @TurnipJF @Tamiyastef! What a round! I did my highest lap count and thought "surely that will be enough for the top 3," but how you all found the extra laps is impressive! Great work, everybody
  9. Today, I gave my Lancia 037 a "sympathetic" restoration: everything was washed (if not using an ultrasonic cleaner), lubricated, and reassembled. Under all that dirt, the car shows plenty of signs of hard use. When it drives as well as it does, though, it is hard not to push it! I take great pride in it being a car I simultaneously worked hard on and get to run regularly. I even managed to get the lights working again: Saving up for a set of Pintopower's Lancia 037 light buckets as we type... It feels good to have it clean and working again: And as part of my mechanical restoration efforts, I trued several comms on my treasured comm lathe: A big technological step back, to be sure, but part of the appeal of this hobby to me is to work on something. Short of going back to mechanical speed controls, this level of involvement is something I enjoy. I can hardly wait to get the car running with its refreshed motor! I was so happy with the results of this refresh that I nearly made a thread about it But this thread exists for endeavours like these.
  10. Thank you! And today, it was on the road for Round 29 of the TamiyaClub Racing by Post series: This is actually the second attempt at this round; the first one resulted in a DNF when the battery died after the first minute. This time, the battery merely died with one minute to go (races are 5 minutes long), but until that time, it had been going quite well. The steering was quite twitchy compared to the 1:10 cars I was driving in the same session, though not impossible to manage. In fact, it became easier to find a rhythm around the circuit with the little Lancia, since turns took less time and there was more time between said turns as the car was negotiating a circuit used for larger scales. It should be noted that almost every round of the Racing by Post series takes place on rather technical circuits for ease of setup, so the 1:24 Lancia eventually got comfortable on a course that requires a lot of concentration at 1:10. And until that battery died, I was well within the possibility of challenging my best result for the session! Throughout its brief run, the little car looked magnificent, a tiny flash of Martini stripes zipping around the chalk corner markers. I can say I am quite happy with how it drives The good handling also puts the bodywork at less risk than I expected, despite rolling the car twice now and damaging some of the decals. An overflow parking lot (which is where I usually drive my 1:10 cars) is more than enough for a chassis of this scale, and it looks a lot happier with room to go full-throttle. For a 130-motor-powered device, this thing is fast! The issue then becomes: how do I repair the bodywork? I am entertaining an order of downsized Lancia Martini decals in vinyl to replace the fragile waterslide types. Replacing damaged body parts with genuine model kit parts also costs at least $50, since I have yet to find someone who will part out Lancia 037 model kits in 1:24 scale. And unfortunately, polycarbonate Lancia 037 bodies in 1:24 scale do not seem to exist. Such is the tradeoff for scale aesthetics at this size... One thing is a bit more certain: I would recommend a WLToys K989 for anyone thinking of a similar project!
  11. Round 2 at Round 29: I had my radio, cars, and all my batteries for this session. Entries included my WR-02C Opel Ascona, F104W Ferrari 312T3, Lancia 037 4WD-H, and the Super Striker. The Ascona posted a DNF when the battery died before the halfway mark. I had high hopes for the Ferrari 312T3, winner of one race and runner-up in another: However, conditions were not quite perfect; as I had not run a pan car recently at this location, I did not notice all the gravel/road salt that had made its way onto the surface. The results were: a persistent grinding noise; terrible understeer, and a disappointing result. It was a shame, as the 312T3 has proven to be one of my fastest cars. So then the SUPER STRIKER made its appearance: Still wholly unsuited to pavement, still controversial-looking, and still putting up results! The lap count was not exceptional, though there is not much more to ask of a Tamiya Striker! And so, it was another attempt with the Lancia 037: I was just short of my previous best lap count despite rolling the car thrice during the 5 minutes. I took the radical step of removing the rear damper spacers, hoping to cure some of the grip-roll that was no issue at all during the previous run. I call it "radical" because this tail-heavy stance ensued: But it worked! I was amazed at how the car's handling transformed for the better with this adjustment. It is clear to me that the 037 is overdue for some maintenance, however... The idea inspired me to try the Ferrari again: This looks familiar: In a bid to improve ground clearance/reduce the surface area for gravel to get under the chassis, I removed the front wing. This meant no front body mount, but it was a (low) risk I was willing to take. It did not solve the problem completely, though it did mean more laps! The motor sounded horrendous at this point. Another one to service, then... With one battery left, it was back to the Ascona: I managed to roll this one four or five times in the 5-minute race. Despite this, it went well beyond my expectations; keeping the speed low to reduce the rolling meant its surprisingly-sharp steering could get to work, and this car was unusually-good in the tighter turns. I even managed to pop a wheelie with this one during the run! (albeit following a post-roll recovery) I had put in well over an hour at this point, but before I went home: The 1:24 experiment continues! The chalk writing is visibly faded compared to the first photos in this post; I made "good" use of the runoff areas! Coming from an hour of 1:10 scale cars, I found the 1:24 chassis difficult to adjust to, feeling it to be quite twitchy compared to the larger entries. However, I eventually found a nice rhythm through the corners, made easier by the longer times between turns (which are also shorter to execute) as the little Lancia negotiated the course. I was actually on pace to challenge my best result for the day until the battery died with just over a minute to go! I really need to figure out a better solution for that... I elected to submit this result despite the car meeting all the criteria for a Not-Classified in the final standings: the way I saw it, a pit-stop to change batteries would have taken over a minute, meaning the final count would be effectively unchanged. Nevertheless, the 1:24 experiment is showing a lot of promise! I just need the car to last longer than 5 minutes... Back at home, the Lancia was disassembled ahead of some long-overdue maintenance and maybe some cleaning: And though the results have not come his way lately, at least Gilles still draws a crowd! (apologies for the lack of taste I need the levity, as you will see...) On a more serious note: my grandfather passed away today, so while it is a small gesture, I will be dedicating my best result to him. But regardless of where my entries end up, I would like to think that getting out there and doing what I love would be the best tribute I can give. After all, it is thanks to him and his hard work that I am here today, and can enjoy the things I do. Best of luck with the round, everybody! I am looking forward to seeing who finishes where, as this looks to be quite an intriguing round
  12. I took a shot at Round 29, and with an experiment to try: If 1:10 requires a lot of room and concentration, could 1:24 strike a better balance of flat-out driving and cornering? I would have found out, but the battery died after minute 1 of 5! I may need some pit-stops to go the distance Unfortunately, one minute was enough time for me to barrel-roll the car, and so the front fender has some nice scrapes! It was hardly the fault of the chassis, though; it handled nicely for a small car on tiny tires, and the roll was due to some previously-undetected debris on the racing line... Being able to go full-throttle was nice, too! I then switched to a larger car: Much more battery on this one! I made two runs, and managed to improve my lap count considerably on the second! I turned my fastest laps in when I nailed my line through corners 2 - 3 and then 6 - 7. The bigger Lancia was a pleasure to drive throughout The chassis design really keeps the weight low down, and as a result it behaves very nicely. Having put in some good results with this car (if not a win... yet!), I hope to place somewhere near the sharp end of the tables Alas, the battery in my 1:1 car died, so I had to suspend further activities! A shame, too; I had the Ferrari 312T3 and the Opel Ascona on deck for some attempts... If only I could have put the juice from all the batteries I brought into my actual car!
  13. Good catch! The map is correct; the labels are not. Guess I went the wrong way on the y-axis
  14. Sorry to hear about that, Grumpy pants! Today, I learned that I can use Imgur to download and post pictures on a mobile device; I am using one now to update the status of my 1:24 Lancia 037 RC car. The day's work comprised tire decals and tiny mudflaps: For more information on this model, a small build thread can be found in the "Other Makes" subforum!
  15. I went further today with the addition of tire decals and scale mudflaps (both provided in the kit): I used the yellow Pirelli decals since I already messed up the white ones, making the mistake of treating them as regular waterslide decals instead of special tire-specific types. I do not anticipate either feature lasting too long, but "scale model suitable for radio control" perseveres as the mantra! The extra care I now need to handle it made comparisons of this model to a precious gem quite apt...
