WOW!! Those are slick!!
What are you using to make your ROV sink?? Do you have a small compressor and relief valve or what?? I would guess it would have to have something that would release air or something so it could sink? Or does it use pure propulsion??
What are you using to set the hook and reel on the pontoon?? Are you using a large servo and levers? Gearbox and motor on reel?? Thats a slick set up! I was into R/C cars and trucks for a while I still have the stuff, and I have REALLY been tempted a few times to get them out and put them all back into running shape. My fav was playing with timing on a 50,000 rpm motor on a 1/10 scale monster truck. She would FLY!! The tires would spin so fast when you were holding it in your hand that they would go from about 4" to about 1 1/2 to 2" wide...much like a dragster on a burnout. lol
"But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your ancestors served beyond the Euphrates, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord.” Joshua 25:15
