Here's a SOLAR powered R/C  barge I built.

I rewired the panel from 20V to 10V. The barge is made of balsa frame and birch ply. It's about 18" wide and 24" Long

That's a 2 1/2" brass prop and custom steerin assembly made of stainless allthread, aluminum plate and other misc parts.

Yep, it's just a very basic barge shape.

I wired it so I can put a battery pack inside if I want.  It will charge the batteries when not running and use the batteries if it gets shaded.

This makes a good "rescue boat".  If any of my other boats malfunction I can send this one out to retreive them

I'll post some videos when I take some.
