I was worried that water would get in the hull as the deck had only 7 tiny screws screws holding deck to hull .So i put 7 blocks in the hull so that I can replace the tiny screws wthe 7 #6 3/4 inch metal screws. Now the deck is secured way better. P/S I haven't been down to the pool to do a test run yet . I forgot that I also updated the Transmiter & receiver to Fly Sky transmiter
