Penguin Fart Racing
RCTalk Qualifier
A friend gave me an oooold speed boat. ( FIRE HAWK; OK MODELS / TAMIYA ). I gutted it and am in the midst of replacing its' MABUCHI RS540 SH ( no load 23500 rpm ) with a water cooled TRAXXAS STINGER ( ~29000 rpm ). TRAXXAS NAUTICA ESC, 2075 waterproof steering servo, 6519 reciever and 6s NiMH will replace to vintage electronics . Rudder was smashed so I made a new and longer one out of soldered sheet brass and brass rod stick. The stock trim-tabs and turn vanes came from my SPARTAN upgrade. With the bow facing forward, the battery box is on thevrear left, while the reciever, ESC, and steering servo is rear right ( see PIX ). One thing concerns me. I know about balancing and wing loading for aircraft and how to check aerodynamic stability for rockets. How should I check to make sure this build will run stable at speed, not roll over or imitate a submarine that does not sink ? How much free-board ( gunwal clearance ) should I have ? Should I add some weight to the bow to keep it from flipping over front-to-back ? Have not given her a name yet; maybe ANGELIQUE, or AMPHRITITE, or maybe the Melmacian Sea Goddess GLUB-GLUB ( think ALF ). THANK YOU !
