Too bad. You are so unlucky. Poor you

I think what George is saying is that the peak amps a controller shows without a ramp doesn't really mean much as it's so short.
I know my Jeti setup went from nudging 6kw down to well under 5kw peak by changing the controller from no ramp to a ramped one. |

Err guys, he was using throttle response 5, which is a fairly slow start and takes away most of the peak..
Yes it will be lower when ramping, but still it's a lot of power. Don't forget Arc is using a big pack, which get's him a very healthy voltage under load. Will the HK200 survive this combo? Maybe.. and that's what I told Arc, it may/should be ok but I think it's borderline. Gerben |

I looked at the file. As Gerben says it is marginal as the watts and current is a bit high.
But I understand the motor is a 1512/1.5D 6.7:1 driving a 17.1 x 17.5. Joe, this is not a high power system. I am surprised the watts are so high. Arcteryxxx, are you doing the usual F5B climb of accelerate climb and accelerate? Or just going straight up which might explain the high watts. The controller ramp is only 0.5 seconds so a 1 second ramp will reduce the maximum to a more reasonable value. These controllers are tough. The current and watts will not kill them, only the heating. I suggest try the ICE200. If it fails then fit an HK200 and monitor it after say 5 climbs and see what is happening. |

F5B - SpeedFire
Thanks George. The 1512 is not a stock motor. Bought it second hand from Mr. Mirov, and at least the rotor is modified and rewrapped.
My flying style is kind of irregular compared to the normal F5B distance task, and I mix between long (3sec) and short (1-2sec) climbs. |

The HK200 will do the amps and more for a short period but it gets hot fast if used climb after climb and you will cook it before the battery or motor. The heat adds up and it needs a long time to cool down. The 1512/1.5 on 6S is right on the limit of what it will do for F5B competition flying with a 17.5 or 18 inch diameter prop. This is about 50% capacity out of a 500 gram pack. If you where to restrict the capacity to less, that would be good. But who wants to fly only 33% out of their battery pack? This is the problem. A bigger battery does you no favours here.
If you have the chance to try an ICE200 with a P125/180 logic board, that would likely kick ass as the cooling path and fet resistance is much better. |

I have the ICE200 which I modified some posts ago. I also think the logic board from the P180 survived. Is it a plug&play solution you are describing and what will be the gain over using the ICE200 logic board?

Some pics from a recent fly in, Speedfire+Backfire+Radiant in the air at once, playing chase and generally looking and sounding awesome.
Some interesting observations between the Speedfire and Radiant, Both running the 2026/3600 Phasor on 6S. Speedfire with GM V1 18x21, Radiant with GM 17.5x17.5. 18x21 Barks more with low airspeed, has slightly higher top end. 17.5x17.5 Accelerates from woah noticeably harder. Speedfire seems to keep slightly more energy going in a glide. HK200 with firmware upgrade died twice.. Ice 200 lite out of the box continues to perform flawlessly All 3 models rock and roll |

A 3600kv motor on 6S with those props you mention is a lot to handle for any ESC but a properly reflashed HK200 should handle it until the point where it gets to hot from running the motor to many times. This ESC has a poor cooling path and high resistance. |

Yeah I killed it from too much "fun button".
First day I desoldered one of the motor phase wires from the circuit board (factory soldering job). I fixed that, and then the next day I killed it again. This time I had no brake so I'm assuming it's more than the single phase again, but to be honest I haven't pulled it out to inspect it. There is a very strong smell of burnt electronics and the ESC caps were too hot to put my finger on... Fully aware I killed it with my own actions, but I was having plenty of fun doing it EDIT: Battery was a nanotech 65-130 2700. Your firmware with the "good" fet board. Capacity used - Quite a bit I would say! I didn't have the unilog in place and I haven't recharged the battery yet. |

Which firmware on Ice 200 lite? |

4.02, Ill probably update it too 4.14 when It gets plugged in next though.
Setup is - Brake - No Delay Strength - 100% Ramp - Very Fast Start pwr - 59 Current Limiting - Disabled Power on beep - Enabled LVC is in Nimh mode, 4V total (ie off) Timing - 0 PWM - 12Khz Throttle is fixed end points in airplane mode, with throtle response 7 I have a 0.6 second linear ramp programmed on throttle switch, |
