    New Product: Engine Kill Guard

    Fellow Gas Boaters;

    Been looking around for a reliable way to shut off the engine. My personal experience is if somehow or rather power gets disrupted to the conventional failsafe, it fails. If you are at WOT, there goes your expensive boat.

    Happen to read the following from Warehouse Hobbies, chek the link. Anyone of you interested? I am planning to do a mass order from them. Gathering more info.

    http://www.whobbies.com/releases/release2.htm

    The EKG “Engine Kill Guard” is a new product designed by; Frank Ackinno and Tony Castronovo of Warehouse Hobbies Inc.
    prompted by a overseas customer to produce a device that is actually mandated in Europe, that will shut a gasoline ignition down in the event of low radio (receiver) batteries or worse a complete loss of power. This customer contacted Tony and asked if anything could be done to get a unit and at a better price.
    He came to the right place. We are very fortunate to have a electronic circuit designer such as Frank Ackinno at our disposal and Tony also has a electronic design background.

    Between the two they quickly came up with a circuit that would do the job and be manufactured at a price point that enables a low retail price. Within a couple of weeks the EKG “Engine Kill Guard” as Tony named it was being tested and ready for pre- production. At the time of this release this product is in the final stages of pre-production awaiting a final printed circuit board. We anticipate that production will start the first week of September 07, and product should be ready to ship about 3-4 weeks later.
    Here’s how the EKG works. There is no battery required and can be hooked-up in a matter of minutes by almost anyone. Industry standard J-series connectors are used. The female end plugs into the male end from the radio switch. The male end from the EKG then plugs into the (Battery In) of the receiver.

    The device hooks-up between switch and receiver power-in. In this configuration you are also protected in the event that a radio switch fails.
    There are (2) 18” leads that rout through the radio box and are connected, one to the engine block (ground) and the other to the magneto “kill” tab or wire. The tiny device, slightly larger than a quarter is housed in the radio box, with only (2) wires exiting to seal.

    The circuit has been calibrated to detect a 4.0 volt output that at which time it will electronically latch (close) the loop to the (2) leads attached to the engine, which in effect will stall the engine. If power is lost completely such as a mechanical failure or a battery “pops” out of the holder the EKG will also immediately “kill” the power from the engines coil and stall the engine.

    A regular radio “Fail-safe” is only good as long as there is power to the receiver, in conjunction with the new Enforcer EKG to your system you have now assured yourself the best possible protection for almost any unforeseen situation.
    In today’s day and age we have to be very conscious of safety for both ourselves and others, and you can not go wrong by investing in devices of this type that can eliminate or minimize a bad situation.

    Some product pics I obtained from the site. From the look of this thing, can any expert out here comment how good this solution is?

      The EKG seems like a great device if your radio does not have a built-in programmable fail-safe function

      For those using 3PKs and other PCM radios that come with the fail-safe feature, the EKG should not be necessary.

      My PCM radio is programmed to cut throttle and turn rudder by around 10 degrees to the right when there is a loss of signal or rx battery is low.
      If in doubt - add more horsepower!

        The EKG is just a Low Voltage Regulator, closing the circuit when voltage is below 4 or zero. If you freshly charge your RX batteries and tape them up, you don't need EKG

        To me a Fail Safe should kick-in when the signals between TX n RX are weak or none, that will prevent your boat from smashing into the concrete wall or hurtin a human turtle and tortoise are constantly accidentally Don't let the SPCA know
        Gone Gas...but Petrol went UP !!!
        now burning NITRO !!!

          Just get a good radio with the fail safe feature.

          These radios can usually store settings for 6 to 10 seperate models so you'll save $ in the long run.

          Although PCM receivers are not cheap, you'll only have to use them on your biggest and baddest boats. Other boats can use the standard FM receivers with the Transmitter in PPM mode.

            Ya.. Agree with Siao Ting Tiang. Bro Dragon, Pls time for you to invest in a good radio and stop using the AM set for your prize boat.

            Everytime I see you run the boat I also stress!!!!
            Life's a joke. Keep laughing....

              You may also want to use a 6V receiver pack like the one below in conjunction with a LED battery voltage monitor.

              The upside:

              1. No chance of cells jumping out of their spring terminal case.

              2. Gives 6 volts which maximises the torque from your servos.

              3. Can be cycled and fast charged using buggy style delta peak chargers.

              I got mine from Hobby Link at Far East Plaza, but they are probably sold by other LHS' as well.

              If in doubt - add more horsepower!

                  The EKG can be DIY yourself going to Sim Lim to source for the component.

                  It's just a simple theory of <4.0V and >4.0V which way it'll go to complete the circuit.

                  It's time you get a good TX and RX with PCM fail Safe.

                  Life is a gift. never regret a day in your life.
                  Good day gives you happiness,
                  Bad days gives you experience,
                  Both are essential.

                    Thanks for all the concerns and recommendations, my TX/ RX is a Sanwa Blazer although it is AM it is quite reliable. Had been trialed and tested to sufficiently meet PP requirements. I am using 7.2 V Nimh Batt Pack for the system. I am looking into geting a Futaba PCm system for flying though

                      Hahaha... Kanna suan by everybody. Get a new tx to use for planes and boat also lor.

                        Haha....even expensive PCM system get glitch yah!! My $30 Am TX and my $15 AM RXs on my TS2 and my Vegas so far never failed me leh....drown in water recover blow dry still running....

                        My Blazer is by far the "most advance" of my system.

                        For Flying Nitro, I went as far as using cheapo china (WFLY) electric RX on my Arising Star 40 Trainer....go as far and as high as my eyes can see and back....I am a beginner in flying btw....

                        Shows one thing...cheap doesn't always mean bad, and expensive not necessarily means GOOD I'll add a failsafe to my Magnum though

                          Actually I had experienced some glitch on my Arising Star Nitro Trainer with teh WFLY Rx/ TX when flying towards me....I figured out might be antenna placement/ routing/ cabling/ pladment of RX...so i rerouted the antenna, put foam wrap RX, and the tested flew an hour without glitch.....

                            Don,
                            Let set this issue straight, Let not sent a wrong idea out. All gas & Nitro powered model boats required fail safe. ''Am set'' or even some ''FM set'' most doesn't comes with fail safe built in, you've been advice on this issue verbally. I hope to have your understanding and comply with the safe boating requirement. Sufficiently does not meet PP requirements.

                              Let me set this straight to you too....I am not sending any wrong idea out. There is no where in the club rules that say that we MUST have Failsafe inside our boats to run, and NOBODY ever told me MUST HAVE FAILSAFE. The rules say to practise wise radio freq check.

                              How many of those running in PP HAVE FAILSAFE, and what makes you think that I DUN HAVE a failsafe. Must I spend a few hundred dollars in expensive radios to run in PP?

                              What I mean by PP requirements, I mean I have run there with my cheapo radios and it works and there is no disruption. Have I caused ant disruption to anyone? So what is the problem?
