Yesterday, 60's sailng club gathered at a lake, and had yacht racing meeting.
At a break time, I released my flying boat as a F1 powerboat.
It has an only 100w powered brushless motor, its speed was about 40 mile per hour, great! And it showed the funtastic action accidentally.
Please enjoy it. Thanks.
