Here is my Volantex RC Vector 80 PRO 798-2 Angry Shark 32" self-righting Mono 100% all stock with gps speed test. I think low 40's is attainable with a good s&b prop and is probably a realistic number for this boat. The hatch leaks like crazy when upside down, so it must be taped. Overall it's a pretty fun boat and seems to be going much faster than it actually is (I guess that's how Volantex comes up with their speed estimates) . It will be a lot better once I get the speed up a bit more. More to come.
