Testing the Sea Perch 0.7 amp Jameco motors mounted on the Sea Hawk.
At Mother's Beach in Marina Del Rey in California EZ Money Harper, his dad Roy Harper and I tested how the Sea Hawk drives with Sea Perch motors (Jameco .7 Amp motors) running off of a 9.6 V NiCd rechargeable hobby battery. They drain the battery fairly quickly and the craft doesn't move all that fast, but it does work. One issue we found we needed to resolve is to make sure we get counter-rotating propellers. In this test we had propellers that turn in the same direction and of course this made the boat turn slightly to the right.
Below are earlier tests of the craft, starting with a series of flotation tests.
The above video shows that, yes, you can test out your Sea Perch in your bathtub - you just can't dive very deep. The up and down thrusters can also make a bit of a... splash. As the Hitch-hiker's Guide to the Galaxy tells us, "don't panic... and always carry a towel."
The following two videos show the appropriate winter use of a condominium swimming pool is for testing your Sea Perch/Sea Hawk/Manta Ray. Wet suit optional.
