So i am completly new to boating and got myself an M41 and got some questions about the boat. I have run it a couple of times and after the first 2 runs there was some brown liquid coming from the near the prop and after about 5 runs i noticed the bottom is not completly flat. I have flipped tve boat 2 times at high speed but thats about it that could have messed up the hull. I got some 3s 5000mah traxxas lipos and after the first run my charger showed that it charged 5020mah and i do have the lipo cut off on so thats wierd. Also when the lipo cut off cuts off the led on the esc doesnt change color like on the most esc's.
