This is the first pics of DD during his first dynamic test in water. One of the propellers do not work in water (it is not easy to turn), but I have an idea for this problem!!! DD is very slow in water like in 1944, but mine has just one propeller.
water inside, but not much after 1/2 hour of test and my electronic is protected.
You can see one track broken at the end, because this tank do not like the sand...















I promise a video before next weekend.
