HemiStorm RC - Chris de Graaf
Halden, Norway
The X-Carve enables me to build what most likely is one of the craziest RC cars in the industry. Starting from an Axial Yeti XL base, I’m stretching the chassis, reconnecting both halves together using a Delrin 6mm bottom plate, 2mm carbon uprights and custom motor bracing.
120 minutes
The Axial Yeti XL is one of the hottest RC cars of the moment. By stretching the chassis I want to double the power. I want to make enough room for two transmission cases, two motors, two speed controllers and four 3S batteries. Basically double up on everything to get an insane power to weight ratio. The first step involves a lot of guesswork. Add tape om the cutline of the chassis halves. Dare to cut, using a hacksaw. I’m sure the video will explain a lot more.

To connect the two halves together, I will be using a 6mm delrin sheet. To make sure the fitment is correct, I make a test run wih a pizza box before machining the material itself. In the final product I added logos and a magnified finger print, to make it a more visually appealing piece. All these files are available seperate. To get the basic construction, just use the file to machine the top, the outline and the holes.

I made twin vertical braces alongside the battery trays, plus a backbone that will avoid torque twist on the chassis. All these parts use either logical places to drill holes in the chassis halves, or original mounting positions for the various mechanical parts already installed in the vehicle. End specs of the car: 7.1 kg versus 5.8 kg in non strectched version, double motors, double transmissions, and double battery space. Taller gearing, higher top speeds, and even a dig setup in which front and rear drive can be adjusted on the fly all make this a unique vehicle with a lot of potential.
