Hi Bo , Thanks for the feedback , this is something I will confirm later , the worrying thing was when I tested the setup with a 11.1V 2Amp Lipo, I did not hear any clicking sound from the ESC and the motor attempted to rotate . ( which I took as a good sign ,seeing as it was so underpowered with the small Lipo) but as soon as I connected a 22.2V @: 5amp Lipo Pack ..the ESC clicking sound could be heard , so did not want to push my luck ...

Do you have a list of your default settings for the USB AP Programming screen ref Your C120xx Motor ? Sorry to be a Pain , but I'm this close to start some serious testing at last .. Cheers

No worries. That's why we are here. I need to connect it all to get my settings. I'll see if I can get it done later today. Busy, busy busy :-)

yes he's back with tales of woe and some progress , OK just spent the last 2.half hours trying to program my monster 450AMP . ESC .. No matter what I tried I could not get the AP software to see my BIG ESC (BUMMMER) . I then tried the software with my test ESC ( 150amp Alien unit as well ) and it connected more or less every time within seconds , I was able to change parameters and upload the new settings fine ..so I knew that side of things was ok (dongle /Cable /Connections) ....

After many more attempts at connecting the 450 Amp ESC, came the Nagging suspicion I had somehow killed my ESC without ever powering it up in anger, started to creep in ( Grrrrrr :-( ) .. in the end I resigned myself to the fact I may have done damage somehow , so removed the 450 amp ESC from the paramotor ready for shipping back for repair if possible . and decided on one more bench test with just the ESC totally disconnected and plugged into laptop... well (Expletive entered here) the damn thing connected up to software more or less as quickly as the smaller ESC and after several go's to check repeatability it was fine ..was able to check the settings and upload new settings OK ( MEGA PHEW )

Only one more conclusion ...I have a wiring issue I have not picked up (damn ) good news is I may have gotten away with my ham fisted attempts ... Just a bit Happy at the moment in the hope that the ESC is OK and I can move forward with this again...

Just another Thank you Bo for the Setup info . My version of the AP user interface is older I think but all the info I needed was found in your photos . Cheers my man..

One last request ..how did you come by the 18° timing figure ... seeing as I have Hall sensors in mine im not sure about this aspect ? :-)

I have been experimenting a lot with the timing. 18 is just my last try. My setup did not work perfectly due to a too large propeller (still waiting for a smaller one).

By increasing the timing you should be able to get more power from the motor. But also a less battery economy. It's all about finding the sweet spot. None of my enhancements have given me anything noticeable. But yes. It should be irrelevant for you because you have a sensored system. In theory, it should find the sweet spot itself.

Not Gone away guys believe it or not still battling trying to get ESC WORKING tried all 36 Combination of ESC wires and hall sensors 3 times now and getting close to admitting I may have done something wrong somewhere and fried or corrupted the firmware cos at the moment I have a expensive brick that clicks like a time bomb LOL ( ok Ok not the best Analogy ) ...

will be back hopefully with some positive news even if it means Bending plastic again ( Bugger ) ..

"Expensive brick that ticks like a time bomb"

LOL, that's exactly where I am but I didn't put it so eloquently :-)

Turned out that on my setup I'd fried the BEC. There's no BEC on my ESC's so I put a UBEC in (which also made it easy to put my kill switch in here too). But I forgot to check its rating before connecting up a 12s pack. Turns out it has a maximum 20V input so I fried it with 47V. With no power the modded servo box won't produce any signal resulting in the ESC's woebegone "I can't hear any signal" beeping.

I have a new SBEC so there's a day of soldering and making mounts before the next try.

Regards, Paul

Hi Paul , thanks for the info, :-) You Just touched on something I'm currently looking at or at least will be once the ESC is sorted , i'd like to put and inhibitor switch on the Hand Controller to prevent Motor operation once the system is live as it were ( battery Connected Master switch On) .the idea being that unless the hand controller Switch is in run mode then no amount off throttle operation can start the Motor. I was thinking about a switch to the UBEC power ? any one with ideas as to how to do this without damage to ESC or suggestions as to how this can be done ?
i.e is this the wrong point in the circuit to make this connection , i'd rather do it on the low power side of the Power plant circuit ( wont require massive switch to deal with possible high currents ) but where is the question , Thanks guys

Yippee! Got one motor turning anyway :-)

I'm going to post a note on my project thread, pop on over because I'll post a bit about my kill switch and throttle too.

Regards
Paul

Hi Guys Mini update. well my project is currently stalled due to what may be self inflicted ESC Problems . Great news for me is that Bruno At Alien power systems has offered to take a look at it on my behalf if I send it back to him ( Er Express delivery Anyone :-) ) and try to let me know what's wrong with it or me for that matter.

All things considered this is great, I bought this ESC 3+ Years ago just for this type of project and only recently started to connected it up for the 1st time . so even though its been in the box as it were he really does not have any obligation to look at this for me. I'm once again impressed by the service this small company offers , yes I may be lucky, but either way with his assistance i'll be better placed to move this project on once he lets me know if its a Now a brick or can be sorted ..

Will keep you guys posted and hope to have some answers regarding, where I went wrong or my next move, to push this project forward :-) Cheers Guys

One other question ..regarding Fuses and Heavy current Circuit breakers , I Notice a lot of these Paramotors don't seem to have them fitted ( well at least not in the high current side of the circuit ( Ubec switches to inhibit Controller ..yes ))
can any one chime in as to preferences and reasoning behind not fitting them ( other than the Keep it simple Ideal) ?
