2023 EFRA European Championships tech info: I'm hereby posting both my dry & wet weather set-up sheets for my XRAY X4'23 cars. I've received several requests for the wet weather setup especially. We actually only got to use the wet cars for one practice round at the EC (much less than first expected) but myself and Bruno Coelho RC Driver used the setup listed below to top the time sheets of that practice round! This setup was developed after running the car in wet at the Swedish Nationals earlier in the summer, and I've also made a more extensive post about that car here. About the dry weather setup, I ended up running a setup close to the one of Bruno, with some minor differences to suit my driving style better. Key things on the setup for the Türkheim track with Matrix D36 tires were: 2.6-2.9 progressive rear spring (part number 308166). This spring helped the car absorb the bump at the end of the sweeper better, and it also improved forward traction. 4x1.2 pistons instead of the kit 1.1mm. Made the car feel more "in the track" and also had better consistency. 3.5 degrees of rear toe. To prevent the car from getting loose, especially during the first minute on new tires. The D36 tires are very temperature sensitive and tend to make the car rather loose, especially on colder track temps. I've also posted my Hobbywing ESC set-up. My electronics ran faultless all weekend, and I opted for the 5.0T motor for this medium sized (but fast) outdoor asphalt track. The 5.0T motor provides just enough power, but with a bit better drivability than the 4.5T in my opinion. The 5.0T can be tuned to be equally quick, just with a bit smoother power band. As for the battery choice, I once again used the Nosram 5700 pack (234g) which has more than enough runtime for the demanding Türkheim track, yet still is light enough to allow for a perfect 50/50 L to R balance of the car, with its low weight and thus, an ever so important low CG.
