Its scratch built off the USCG plans I got the plans from the USCG museum. it is self righting I have 6 12v 3.4ah batteries in it 4 for the motors and the other two run the misc electronics. I built boxes that hold the batteries in place into the bottom of the boat and since those batteries are low profile all the weight in the boat is at or below the waterline. so it has no problem rolling back over.

Hy, escuse me for delay

I am interested about photos during execution of the model, and some with principal plans (at the final stage)

thancks a lot

Beautiful work!
