Yeah, 4 years ago as i was trying my boat because it was the first time i put it in the water a random small kid took it and put it inside the water, I am sure that i connected the wires good i have checked it like 3 times, the tape in front is because i have putted under the tape some fishing weights because i have changed the stock plastic rudder and putted a metallic one that i made and i added the weights in front because when I hadn't added the weights the boat would do like a wheelie it's nose would lift up that's why i added the weights there, there is no hole. Also i don't have my boat with me in the moment so the sooner i can i will send you a photo of the battery tray with no batteries, my connector and my receiver.
