    Hi chaps, I just purchased a Thunder tiger for a bit of fun. First test in the gold fish pond found that the front section which is not sealed from the water makes the sub nose heavy as it fills with water dragging the sub down. As anyone on the forum who owns a Thunder tiger and knows how to over come this problem please let me know how they dis it. Without the front section the subs works fine.thanks

    The dome in the front does fill with water, it is supposed to. I added larger holes to drain quicker when I pick it up. Water leaking past the plate in the front is bad. The balancing will come from the weights on the bottom of the sub. There are round disks that you can move forward or backward to get you sub leveled out. on the surface you need very little out of the water.

    I do own and love my Neptune.
    Here are some mods I did: https://forum.rc-sub.com/forum/builder-threads/2740-thunder-tiger-neptune-sb-1

    Hi, thanks. I will open up the drain holes at the front and rebalance the sub in the bath tub. The only add on is a GoPro 7 camera. I may add some more lights at a later date. But it looks like it will be fun playing around with it.

    You will need to counter the weight or add buoyancy of the gopro. If you mount the GoPro behind the dome, you can make any floatation or weights removable with the camera. That way the main ballast weights are not constantly moving depending on you running setup.

    Hi, I am going to mount the GoPro on top the sub. By removing the dome section allows me to mount the camera on the flat section. I also have the front video camera. However you need to run the lead from the camera to the screen, and the GoPro is a much better camera with better resolution. The sub will be back in the fish pond over the weekend to test the camera out.
