As the speed run thread has started a new category for silver can cars, I thought I'd have a go at it with my Mad Bull. I've been wanting to mod the chassis for a while now to improve on the stock steering installation, and also want to be able to use LiPo battery packs. So the first thing to do was to remove the excess protrusions from the inside of the chassis and make a slot in the back of the bathtub: to allow fitment of the LiPo into the chassis: After that I made a new plate to install the steering servo. The plate allows the servo to be mounted lower so I can bin the stock steering connecting rod, which I replaced with a old 3 step speedo connecting rod. I also machined a slot into the back of the plate to retain the radio tray, which is going to sit behind it: This next pic shows the steering servo fitted, and the foam I fitted either side of the LiPo to hold it rigid in the chassis: This is new radio tray, which when secured also holds the battery in the chassis: It's held in at the front with slots machined into both plates: Made some brass 'body mounts' to screw into the chassis to hold the radio tray down: Radio tray fitted with body mounts. I can remove it by just pulling the 2 body pins. The next pic shows the radio tray populated, there's even room for the GPS speed meter: I can even read the GPS through the drivers window Not bad for a (long) days work, tried it out on the drive in the dark but it's been raining so nothing but wheelspin and white sparks coming out of the motor at full throttle. Need to wait for an opportunity now to run it and get a good speed measurement.
