Darin's Voracity "Race-Prep" - Taking it "One-Step-Beyond"

[LuckY07]

Hey gang... anyone who might have followed this thread... Found out 2 things from racing it at the 2016 NAMBA FE Nationals.

1) Dynamite 160A ESC has a 180A "Safe Mode" limit. When you hit 180A, it engages "safe-mode", and you are now stuck in "limp-home" mode. Will get you back to the dock, but not at any kind of speed. Only way to reset is to remove power and rearm. Cost me several laps off Offshore, as I'm pretty sure that the motor could have handled the additional Amps. Not sure if this can be disabled. That said, the ESC is ROCK solid and performed great, so this IS a nice fail-safe to have for sport boaters who may not have the tools to tune to the levels racers do.

2) NEEDS BIGGER TURN FINS! At racing speeds, if you want to keep the boat cornering at high-speed, you need much bigger turn fins. The ones I added in this thread are NOT adequate. I need to make some new ones, but in the meantime, I dug these out of my spares box and did a makeshift fix, which allowed me to run WOT through the entire Offshore course. Had I done this earlier, I think I would have placed much better in the class, and might have even won it.

Finally, I ran the boat on a pair of 4000mAh 6S packs in parallel. The extra weight helped a lot. Batteries were placed about 1" forward in the battery trays, and the balance seemed about perfect.

Just wanted to provide a little feedback. Boat definitely handles race conditions great, once setup as described!

Great info Darin!

I was checking out a build online (45" Thurgarcraft) and came across these turn fins from Australia.

I wonder if these would be a good upgrade on this boat.. They are 90mm x 43mm.
