How did you end up with programming? I have the same card with the Turnigy Marine 120A esc but the card will only access the first 4 basic satup options. I want to change the timing but can't get the card to get past option 4! front cover states I need to get to option 9. Any suggestions?

Hello
The ESC itself (T 180A) has only 4 options: 1.Running mode 2.Lipo cells 3.Low voltage cutoff 4.Timing The other options are for the ESCs that have those options. As for the settings,you can use as folow: 1-1 2-1 3-3 4-5 Please see the esc manual (under files in product description) as the settings order is different from the card picture. Regards |

Paul_t,
Thanks for the info, I now understand this esc only has 4 programmable modes. I'm having problems cooking batteries the 120A esc's seem to be ok with temperatures keeping below 50 Deg C, but 3000,4s,40C Turnigy Lipos are heating to overexpand. I even tried a cooling plate, which helped but did not stop save the batteries. I have destroyed several in the last few runs. The only conclusion I can come to is to turn down the timing. Does this make sense? Boat is an apparition with Lepard motors 28/60 which also stay relatively cool. |

Kruisen,
I have changed to the nano-tech batteries with a high c rating. They seem to handle the quick discharge a lot better. |

Hello
I would suspect also the props.What props are you spinning? How many KV have the motors? How many amps do charge back after use? Also you can decrease the timing on the esc. I use turnigy 40c also with T180 but never went above 40 degrees Celsius. Regards |

Guy's
Here is my set-up. This is cooking the the battries (see my post 18 July) - Apparation twin motor setup - props as per supplied with boat 35mm dia (4 pitch I believe)sharpened and Balanced - motors Lepard 2860, 2730kv, run at approx 40-50 degrees C - Turnigy Marine 120 ESC's, run at approx 40-50 degrees C - All batteries charging to 4.23 v per cell, balance within 0.01v between cells - Aluminium cooling plate installed on top of batteries brings battery temp down about 10-15 C but not enough to save the failures. - run times kept low, ie 5 to 6 race laps only - Batteries tested to date and results include - Turnigy 4S, 2650, one per motor, heat to 60C then cooked one only on 2rd run - Rino 4S,3700, one per motor, heat to approx 60+C expand but still just OK, as seem to be overexpanding and won't survive or long. - Turnigy 3S, 3300, one per motor, cooked one only on 2nd run (opposite motor to last cooked side) I know the calc of motor 2730*14.8V = 40,400rpm is high so tried 3S batteries also as 2730*11.1 = 30,300rpm but still too much amps. Have even melted solder on the battery leads. So I suspect that each motor is pulling 100+ amps (have not measured? not sure how to measure in situ). Also not both motors pulling at the same rate, but random which side overheats. Options may be a)smaller props to allow higher revs to keep amps down b)reduce the motor timing which has been set at factory setting of 5 (15 degrees) c) New motors with lower KV rating d)other?? The next test will be with one large Turnigy 4S 5000 battery setup with 2 motors in parallel as may handle the higher total combined amps, also with motor timing turned down. Any help/advice welcome as cooking batteries ie becomming an expense hobby. Regards |

Hi.
I checked out that your motors are rated at 60amp max so 100amp is dangerous and probably explains your battery heating problem. Propping down to 30- 32 mm props will bring the amps down. Keep on going smaller until you get in the 60amp range. A great way to measure your amps is to use a Turnigy 130amp and watt meter. Plug it between the battery and esc. I wrapped mine in a plastic bag with rubber bands to keep water out. I had a look a the original set up for this boat and guess you have followed the same layout ie just the one rudder with it's built in water pick up. If this is the case you may not have sufficient cooling for both motors and esc . This could be affecting the boats performance too. Maybe a pick up behind each prop for each motor/esc might help. Cheers Grasshopper |

GH, thanks
I think water flow is OK as the temp of the esc's & motors seems OK, but would still like to have more water flow as you suggest. Has anyone ever seen a small rudder setup with dual water pickups? the Apparition hull is not well suited to fitting separate pickups. Regards Kruisen |

HI,
generally in boats you need at least 5000mAh and 40c. my stock genesis set up is heating the 4s 4000mAh 40-50c packs to 60-70DegC!!! So far no failures... I got 8000mAh 30c zippys and no more temp issues with the batteries also near twice the run time, I use a metal 440 prop from HK balanced and sharpened. So I suggest your pulling more amps than your batteries can handle hence the heat. I would change down in prop till I got bigger mAh batteries if I was you. |
