Build wakes. Whip the tube. Send it.

Hold throttle and steer broad circles. Your wake persists, spreads, and fades. Loop back and pull the tube across a bright wake to launch.

Published dimensions and propulsion layouts are applied. Exact acceleration and wake calibration still depend on propeller, ballast, passenger load, setup, and measured test data.
