I have been flying CS-10 with 2W20 and 3S 3000mah, Thunderbird 55 for over 2 months now. Even with a good percentage of WOT, the battery was only warm after the flights.

Could you do 1 more test with the same 2w20 on WeMoTec Minifan with 4S, to see if the current is around 50A?
Thanks in advance with your help.


The difference in amp draw could caused by high/low timing, exhaust diameter, ducting ... or the accuracy of the meter .....

How long can you stay in the air with that 3000mah pack? thx.

for reference:
the 2W-20 is used with 3s lipo packs.
3s, 10blade 70mm fan, draws about 55amps
Amp draw was 30 Amps with a minifan
