Thanks for posting this! I really appreciate the support from people at the event:

1. Cool responses and advice as how to improve the car or what could be worth trying out on it.
2. Video and photo footage!
3. The support on getting the car up and running (when it broke down).

Break down? Yes, it did. The end of the video shows the car sagging, and it was one of the ball connector nuts undoing themselves of the screw (no loctite, woops)! However, I had some breakage of 3D printed parts - hence why I was not jumping the car. I hope though it still gives an impression about the car.

Some info about track, conditions, car and setup:

Track & Conditions:
Clay surface, dry, very bumpy and quite dusty.

Car:
12T/3100kV Motor, Sensorless
Total weight: 1470 grams (just a few grams too light for BNK regulations).
Weight on front: Approx 1100 grams.
Weight on rear: Approx 370 grams.

(For comparison, my TRF201 was 1560 grams in total, 1030 grams on the rear, 530 on the front).

Setup:
Front Tires: Proline Caliber M3 (nearly new)
Front damping: #300 oil (Tamiya)
Front spring: Associated 'Rear' Red
Rear Tires: Proline Holeshot M3 (nearly worn down to slicks)
Rear damping: #300 oil (Tamiya)
Rear spring: Associated 'Front' Blue

The setup proved to have too little damping (not surprisingly actually, I just threw them on there on the build, my TRF201 uses #400 oil on the rear and #500 on the front. The springs seem slightly too soft up front, and I may need softer ones on the rear. I don't know how visible it is in the video, but from the rostrum you could see the rear wheels bouncing like they were on drugs

PS: The applause was for finishing the first lap, as the first time they saw it run it broke down on the first jump!
