Hello, recent I also brought the seawolf and would like to use your method to make it static dive. But, I have a queston, when keep pumping the water inside, how did you know the water bag is fill full of water?? Because you don't know the bag is full as the hull is sealed you can't see it. If keep pumping the water inside, the bag may explose if full. So, is it necessary to add an auto-cutoff switch which to stop the water pump motor when the bag is full of water or anyother method to avoid this problem???

Regards, Andrew

yes ....the limit switch is necessary for safety
since you can't see the bag inside the WTC but yu can see the submarine from water line
when she is diving I just take her to the periscope depth never goes too deep

best regards

Hello, I have the 12V lead acid battery available on hand, so I want to know whether can use the 12V instead of the 6V for the Seawolf? Is it too much power for the motor? If can use the 12V,  will also change to use 12V water pump instead of 6V pump, is the 12V pump will too strong for the water bag?</p>

Also, please advise what AMP speed controller need to use for 12V battery, 20AMP; 25AMP or even higher 40AMP?? Is the AMP depend the type of motor I use?</p>

Thanks your advise,</p>

Andrew</p>
