After todays maiden and consequent testing, I when home and did the following.
Changed the ESC timing to high and raised the frequency to 16 (maximum) and removed the ESC to motor extension wiring. I drilled a hole through the tubine housing and routed the wiring directly out the side (to negate the need for the extension harness) same as your setup.
Then I removed the ESC and ran it at idle (I mean just spinning) behind the EDF to assist with cooling, after 1 minute it was warm at 2 minutes it was hot and after 3 minutes it was 43' C.
Pretty sure the ESC is dodgey!
I redesigned the rear of my canopy with a cutout to lift the ESC into the airstream and fitted a wedge to lift the ESC up into the airflow.
As luck would have it I had another DLUX 100 amp ESC, and after some snappy soldering and a few programme changes I tested the new setup as before.
After 2 minutes the speedy was cold after 3 minutes it was just starting to get tepid.
Then I reinstalled the whole shooting match and did a full power test.
The amps spiked at 97 for 2 seconds then droped back to 85.
Seems to be OK but I will find out tomorrow with a flight test down at the field.
Just have a funny feeling that the 40C battery may be an issue and may need to go with a big Nano, either that or as we originally thought, maybe the DLUX just cant cut the mustard.
