Mike if you could make something like that cause I would like one, I can't seem to find any of those killguards in Oz m8.
But for sure I will be doing something to the battery connectors before I get the boat back into the water.

Hi, looks like i better start making a new boat for you Iam glad the boat did hold together but sad it happened , send me your email and i will send some setup photos
for you

Like I said before m8 shes a solid boat and still will be after I fix her up, Thanks for the offer of the set up pics will be sending you my email addy. Would like to get the 100kph and Im sure Daniels motor has it in her just have to set it up right.

RE: A lesson learnt
Here's the info for the ekg you can get from WH.
Enforcer EKG (Engine Kill Guard)
Our Price: $39.95
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.
http://69.49.183.35/SearchResults.as...11&Search.y=14
And yes m8 had a run in with a buoy a few months ago so this boat had its fair share of dings m8.
Hopefully in the next few days she will be back in the water.

If the boat is at full throttle and you loose battery power the servo stays in the full throttle position .

Not if you use the type of servo that floats when there is no power. Coreless servos will not remain locked in a given position when they lose power and the return spring on the Zenoah engines will close down the throttle enough to either kill the motor or make the boat go slow enough that it will likely not be a danger or incur significant damage.

I seen that these coreless servos are quite expensive especially if you were to buy them down in OZ, Think I will go for the killguards with 4 boats thats expensive enough..
Just a pic of the Jordo all fixed up, just needs a touch of paint and back in the water she goes,, ????? um with a killguard this time.. lol.

The engine kill is a great thing to do however. I use coreless servos since I am already using digitals. Once you are looking at diigtal servos coreless in many cases is not any more.

Also on all my HD applications (BIG boats or planes) replace that totally inadequate conntector with an industry standard Deans high current connector or such. It may be overkill but I've had the same thing happen using those itty bitty battery/reciever connectors!! Shrink wrap all your connections and get good at soldering, it won't happen again.

Ah,, These plugs I have them on my Electric Plane battery, Now why didn't I think of that. Good idea m8 Thanks..

RE: A lesson learnt
I use heavier gauge wire and higher amperage plugs on big planes and helis. I don't bother on a boat. OEM plugs are rated at 3 amps continuous. This means full they can handle 3 amps all day long without any heating or increase in voltage loss. It does NOT mean as many people think that the plug can only "handle" 3 amps.
The highest load you will get on a boat would be if you fully stalled both servos. This does not mean fully deflected under load, this means stalled, as driven against the stops, etc. Even then you would be very unlikely to get greater than about a 4 to 6 amp load depending on the servo.. Since stalling servos is bad for them and a properly adjusted linkage will prevent that, then the average real life loads are well below that.
Interesting bit of info. Several sources indicate that during flight on a large multi-servo plane that average current load is around 3 amps. Spikes of up to 20 amps are known to occur, but 3 amps is the average. Helis, with 5 servos thrashing around in hyper-aggresive 3D see average loads around 3 to 5 amps.
So I doubt that a 2-servo boat will see loads in excess of what a 14 servo airplane does, or even the 5 servo heli. Hence my thinking that high amp wire and plugs are not really needed in a boat.

Issue is not the amps. It's the itty bitty gauge wire, and puny press fit connections, that in something like a gas boat or plane that is subject to very high vibration, WILL fail over extended periods of time. If you replace all your wiring regularly, then i guess its not an issue, but once you've lost a multi thousand dollar model to those connectors/wiring, that tends to change your viewpoint a little

RE: A lesson learnt
OK, that has not been my experience. I have never had a connector or wire from a battery to the RX fail.
And amperage IS the issue for the wire and connector. On high amp load installations they can become the limiting factor causing a dramatic drop in voltage. But in a boat it is just not a concern.

RE: A lesson learnt
And more practice is what im getting at the moment, while the jordo is in dry dock I was adviced that if I wanted to get more speed I should move the strut to the read pod and offset the rudder to the right. So now have more holes to fill in..
