i have soldered both the parts of dean the other way :p so ultimately should that matter??
and i had 1 sucessfull flight as well :p :p all this i've mentioned before

its not a problem.as long as +ve connects to +ve and negative to negative there will be no problem

Something-This word doesn't hurt to type it completely.

My inference.
Those ESCs can run on both 3s and 2s and might be warm for a full throttle.
and i have overpropped a 9x5 prop instead of 7x5 on a Emax 2812 motor and it still gets a little warm after a complete run.
so over propping and battery issues are ruled out. wolfpack comes with those dean connectors readily soldered for 3s and 2s so there is no way lance got it wrong on the Lipo. either it is a faulty ESC or a short circuit or you have reversed the polarity on the ESC. and i dont see a heat shrink sleeve on the ESC soldering this might have short circuited the Lipo,
Please bother some reading instead of considering this forum as a one stop solution for all you wooes. i have used a 6 volt 3A power supply to check a ESC without prop on the motor.

Bring your Cub (just the fuselage only) next time you visit.  After I check the wiring, I'll use the watt meter with a new 3S 2200 mah and the 9 X 5 prop.  Then we will know the power draw.  If it sucks out more amps than what your battery is rated for, you will swell the lipo.

A 1700 kv motor and 9 X 5 prop is an unusual combination and since I've never tried that combo myself, I'm interested in the results.

Thr is no way any short circuit could have happened bcz I told previously all these happened when I was giving a demo and that too with two lipos ., I was able to save one.. Ty v2 for ur concern, but I've tried to engage myself as much as I can with the threads..
Oh you could have pmed me that yesterday lance... Well I'll be visiting again very soon and till then I'll not open the cub.. Surely we'll have to figure out whether I missed sth or if that's a manufac defect
