Exactly like mine. Now with the YGE205HVT on auto timing, all is fine.

Sometimes it's weird with ESCs.
The ESC is confirmed working with the GA8000, but some users seem to have problems with it.
I have a similar problem with the BEC of a Scorpion Tribunus 130A.
It's working on one plan and on the other it quits the job immediately. Of course manufacturers blame everything else but their ESC, but let's see, if this issue is solved by a replacement ESC.

I actually started using the motor with a Scorpion Tribunus 200 - that worked very good with no heat build-up in either esc or motor. One day the esc just stopped working...no drama, no smoke, just turned into an aluminium brick. If the Hobbywing esc does not work, then I will change to either YGE or Scorpion.
We do agree that the regulation frequency (PWM) is not an option to adjustin the HW200, correct?

I've nearly never adjusted the PWM and I don't think, that it will have a huge impact.
Timing is very important with HW ESCs.
I set it up to 25 degrees of timing, which is the minimum on motors with 24 or 28 poles.
I set once a HW 130 to 18 degrees and the ESC stopped working due to timing issues.

Hi,
the Timing depends not only on the number of poles, it depends on the rotational speed of the electric field (shaft rpm times poles/2),
winding R and L (not known), and the motor load (proportional to current). Turning on the voltage on the winding,
it needs time to reach the max. current (U/R) depending on the Time Constant L/R. To compensate the timing responce of the
winding and the resulting magnet field in the winding, an advance timing must be used to reach the max. torque of the motor.
If the timing is set too high, the direction of the magnet filed in the winding could be in the opposite direction of the rotating magnet
field of the rotor. As a result the motor stutters, it is like a backfire ignition on an IC engine.
Using a low timing is normaly not critical, you will have less power. Seting the timing too high you can damage your motor due short
torque ripples in the opposite direction and too high currents. Also the Timing e. g. 15 deg (mid timing) can be different
on the various brands of ESC's, the Timing is not a normed value/unit.
Your motor can run very good with 18 deg with an ESC brand XX, with brand YY and 18 deg maybe not. It is sometime hard to find out
what is the best setup. Running a motor with various loads from CT to WOT, the auto timing setup of
premium ESC brands like YGE, Kontronik or Scorpion is perhaps the best choice.
PWM frequency:
The PWM frequency has a big impact on part load operation efficiency. Turning On/Off (PWM frequency) the supply voltage leads
to high ripple currents in the motor winding depending on L/R, higher PWM frequencies reduces the amount of current ripples and
thus you have a higher motor efficiency. Most ESC's have freewheeling to reduce the power loses of the FETs during PWM operation,
thus higher PWM frequencies than 8 kHz could improve the overal efficiency.
Best regards

I have done some more testing with not that good results. I still cannot get the setup to work properly. Started on 22° timing and went down to 18. THen the esc cut off at low throttle, just like the first edition did. Luckily I got it recorded and have sent it to the distributor in order to have them take the esc back:
It is very strange to me that the esc just juts off like this. I might try one more time at timing set to 25° on the HW esc, even though I agree with Micha that lower timing should lower the amp usage.
I contacted Dualsky, and they recommend the Jeti Spin Pro 200 HV. I contacted Jeti to get their view on combability, and they says okay, but make sure the filtration setting is set to High.
The Spin Pro 200 has been ordered and arrives next week - but I agree on the auto timing function on the Scorpion has proven to be very good. Should I cancel the Jeti and get a Scorpion Tribunus II 200 instead?

It is a good suggestion - the Spn Pro 200 arrives tomorrow, hopefully it will be able to operate the motor...
The newest software for the Jeti Spin Pro 200 has a Filtration option, which should eliminate problems with high pole count motors, please see the photo from the software update. I hope to make the final tests tonight.
Dualsky themselves recommends a timing setting of 25° for the Jeti Spin Pro 200.

Noch nicht gewogen, aber leichter als mit DLE111 (Ich habe auch eine V1 mit DLE111)

+/- 6 - 8 Minute.
Leistung ist mindestens so gut wie mit DLE111.
