Join frame dots to frame dots. Wheels need an axle diamond. A motor drives connected wheels; a connected battery supplies finite energy. A propeller pushes along its arrow. Foam is light and floats; steel is stiff and heavy.

Choose a part and tap the paper, or drag an existing part. X/Y, Rotate and the part list support keyboard editing. Undo restores whole graphs. Loose parts and builds over the course limits cannot Run. Open Course sketch to plan for the actual road and ink.

Drive with A/D or ←/→. Space brakes. Choose wheels, propeller or both to conserve power. Reach the flag upright with a functioning cabin and hold it briefly inside the goal. Impacts damage the cabin; sustained loads break joints. Stop & edit restores the sketch for repairs.
