Not exactly today, but over the week-end, I was in a vintage RC event in Belley, France... First set of pictures...

The 917K required some colors... I thought about red/white, green purple and blue orange, and that's the last one I chose... Normally, the 917K should be ready for Belley

The Zerda ran at Montluçon few weeks ago. But it was with the main belt longer than what was required, with adjustment of the tightener rollers diameter to make it fit. The proper belt arrived the day before Montluçon, and I had no chance to change it before the event or during the event. I decided to do it today... I can't imagine doing this on the field... Anyway, it's almost done now...

It's a bit too hot right now to do something else, so I finalized the 917K and published it. Again same process than for the others was applied... The accessories for the Delta Plastik Porsche 917K (available at Mantua Models) are now published on Makerworld as well : https://makerworld.com/en/models/1469621-accessories-for-a-porsche-917k-body-and-st1-chassi#profileId-1533759

Finalizing the files takes time. I first added all hardware in Fusion360, then made the joints, then organized and then took snapshots... And all this to make a simple instruction manual... A few hours of work! The 917K should be quicker as there is way less parts... And finally, the accesories for Sabulatech Ferrari 312 can am bodyshell and ST-1 chassis are on Makerworld : https://makerworld.com/en/models/1468588-accessories-for-312-can-am-body-and-st1-chassis#profileId-1532479

Just published an alternative battery fixation allowing for quick release... Battery Quick Release for ST-1/EF-209 RC Pancar by SilverTriple MakerWorld: Download Free 3D Models The principle is simple, it replace the bridge I implemented initially with 2 parts and a reusable cables tie with scratch...

During Montluçonnaise, my friend Benoit put a box with some goodies in my truck. I was aware of the NIB, but did noticed the assembled one only later, and I only check the content once home. So in short there is a Tag Jet 1/10 NIB and another one, assemble. There is few differences between the two : the NIB has gold anodized chassis parts while the assembled one is not anodized. It may or may not be a Tag Jet, although the decoration of the bodyshell claim it is a Tag Jet. But it could be very well a Robbe Geronimo... One thing missing in the NIB box is the sticker sheet with the colored grid (I'm 100% sure it was stickers as it is stickers on the assembled one). The plan will be to model the chassis, repair the broken one to run it (eventually with some improvements), and for the NIB, I'll see later if I'll asemble it or keep it as NIB (this type of NIB screams "Assemble me, please!" :-)

I procrastinated a lot recently... The publication for the 312 bodyshell accessories is still awaiting I do the instruction manual, and I had to finish the 917K accessories... I defined the cut line for both arches and the side line. A printed part will do the job... The way to set it is pretty simple : set first hole using the rear wheel center, then fix the part, then set front hole. I also reviewed the rear end and front end slightly in order to have a better correspondancy to light positionning with the real car... The target is to publish both the 312 and 917K accessories over the week-end...

I ran the Zerda 2GT on the Track in Montluçon during the event, and TravelinTravis from rc10talk was there to take a short video -Thanks Travis!

There is a DXF file on Makerworld for this, within the files I provided. I got my Kydex chassis cut at the local fablab, and one friend told me he was going to cut one in a nylon piece with a scroll saw, like they were doing within the old good times for prototype... Somehow, I'm way more advanced that what it was in the vintage old good times... So, yes, anything is possible as long as you know what you want to do... And in anycase, the G10 chassis plate is available via Factory Works as well : Silver Triple 1/12 Pancar chassis - Codename EF-209

well... I'm assuming printing a set of parts would probably cost online about the price of a very capable printer such as a Bambu Lab A1 mini (without AMS lite - about 200 bucks), based on a recent experience from a friend who tried to price a lunchbox junior rc transformation. When discussing with him, that basically what decided him to jump and buy an A1 mini. Now, if you have a fablab near you, you may contact them and them may be able to help to cut a chassis plate or to print the parts you need. That being said, I designed the car with ease of print in mind, basically to help any one who would start printing with this... In terms of material, this is not much (you may rely on a single roll of PETG for the whole set of printed part - colors are really optional, and it is even not consuming a lot of that roll of filament - about 150 gr of filament). And 3D printing is way more easier than what it was a few years ago... And I tend to forgot that the chassis plate is not printed (although the STL is available), I made the kydex chassis at my local fablab, and the cost of the cut was very minimal, to be added to the kydex sheets. What cost the most on the 2 cars are the bodyshells, the G10 chassis plate cut by Factory works on the Vaillante and the set of wheels (Kyosho Fantom) as I did not found better solution yet...

On the sunday, there was less people, and most of the guys of the club wanted to try the pancar. This gave me the opportunity to gather reliability data with a quite intensive stress test... The car ran for about one hour and a half with a few pilot. One of the guys changed the diff settings after playing with the radio settings... And the car got an even better handling with a diff set hard... I suspect that would not be suitable for all the tracks, but here, and within those conditions, it turned perfect. The Kydex chassis flex seems to behave slightly differently as well from the G10 chassis. I will need more testing time at some point... The key thing is that the PETG diff, to my surprise, did not fail. The car is light, and that is certainly contributing, as well as the 100% infill which reduce the risk of distortion due to the temperature, although the diff tooth are small 48dp). I still have the third one to build, with the 917 chassis, and fortunately, one of the guys built the chassis (again as an experience to gather feedback) : the feedback was positive, and the chassis should be ready for next vintage event...

The Vaillante won the 1/12 race, although I suspect the organizer got this framed looking at the first curve events :-) The car handles great, and both configuration were running great, as long as we have the right tires (Kyosho Fantom wheels with the center hole redrilled to the right diameter is the right solution). I will publish a video later with the other configuration, but here is the Vaillante driven by TravelinTravis from rc10talk

Back from the event yesterday... It was great, and I have a few elements to sort out : in particular pics, vids, and getting the vids from my cars that my friends took while I was getting nice runs with them... I will have to properly write about it but it was a very nice event... And awaiting the pics/vids being sorted out, a few take aways : the offroad track was super pleasant this year, and for both 1/8 GP and 1/10 EP cars, with a very nice and vintage dirt, which looked like a mid eighties offroad track and definitely not a modern one few cars had their first runs there : Racing Buggy, Zerda 2GT, Optima Mid 60th, Pancar 1/12 in Vaillante (Fiber chassis, Kyosho shaft) and Leader (Kydex chassis, M3 threaded rod shaft), with different tires, allowing for a clear validation of the chassis, with a lot of run time, and even some validation by pilot who tried the cars There was a guy, there, his pit table was fully old school mode, up to the batteries charging and discharging pod- And none of us were as vintage spirit than he was, even the GP old school guys :-)... The Zerda 2GT is great on the track, and it did not belt slip :-) The 380 RS well geared is a quick as a 540 silver can and the Racing Buggy was way quicker than I expected The Fantom tires are really suitable for my pancars. The TPU 60A may still have interest for drifters while the EVA Foam may be very interesting if we find the proper density (what I had until now was way too hard) We race a bit, for the fun. Got my first victory with my pancar 1/12 EF-209. Also finished 2nd with the Turbo Scorpion during the Offroad electric race stress test on the PETG pancar 1/12 differential has been surprisingly good - 1 hour and a half continuous run and no broken diff. I broke a nylon printed differential on the second pancar. I'll have to make some check, but I believe there was two element caused the problem : the ESC was not set in F/B/R but F/R, and the motor pinion was not tighten enough which made it more difficult Beside a broken diff, the Optima mid ESC died before I made the fourth run with the car. The on/off button appears dead, and I will probably have to replace this ESC. And there is so much more to say, but first I need to sort pics and vids...

The Montluçonnaise is nos in less than 4 days. I decided yesterday there will be one car built on the track during the event... I did print a full set of part, and tires will be delivered onsite during the event. And I rushed the design of the bodyshell supports for a Porsche 917K by Delta Plastik (available at Mantua Models). I'm still not happy with the rear end, I need to rework it. But the general idea is there, and the position of the lights at the front is trying to mimic the caracteristic light positions of the 917...
