I'm putting my money on the cells.

Have you tried changing to KAN 950 cells? They should work wonderfully with the amp-sucking 480 motor. Get it from SHS. Or PM me.

base on what you said, it will be drawing rather high amps on 7x4

try 7/8 cells kan 1050

6x4 folding or 6x3 folder.

run a 30amp esc from SHS should be ok.


full throttle run time should be around 3 to 4 mins. flight time.

thanx for e detailed infos n help bro!!
i jus replaced e cell with a new kokam 2-cell 7.4V 1500mah(super high discharge)...doesn't cut off anymore...

That's good to hear.

With lipos, you gotta be careful again. Those lipos do not like getting discharged to less than 6v. Your ICS400 will CUTOFF AT 4.3v/3.2v which will totally toast the battery. Be careful.

According amp draw, I suggest you fly a maximum of 6 minutes.
