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...

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...

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 ST-1/917K was built with a dedicated remote control set, so I can hand the car to anyone so they can try during events. The remote is a crappy super cheap set, and may not be the best for this, and while everyone who got the car in hands complained about the remote, they also noted the chassis has quite good potential, and they mentioned it as comparable to a Fantom in terms of handling...
The feedbacks were overally super positive, and even more when the people understand that cost for a build is not much at all...

Another Video in Belley, but this time with 2 ST-1 chassis...
The Vaillante was running a Brushless 21.5T motor, while the 917K had a brushed Kyosho Le Mans 490. For the 917K, the driver was used to drive 1/8 GP cars, and it was more or less his first venture with an EP 1/12 car. The Vaillante was drivern by someone who tried the 917K already and complained a lot about the remote. My own remote allowed him to sense how much the chassis was well behaving, and based on his feedback, I may have to add some cuts to the chassis plate to give a bit of flex to the rear pod. That said, with the better remote, he clealy said as well the chassis was a very sharp and good basis (he compared it to the Fantom, which is quite a nice compliment already).
