Hey guys,....I am by no means new to RC Heli's, built, owned and flown many 450's and 500's but never a 700 size electric heli and I have recently hit a wall. I am now the proud father of a Goblin 700 that is nearing completion and all that is left to purchase the batteries. This is where I need your eperience (and thanks in advance for any given).
I have searched the forums on this and many websites but found nothing specific to my question....How do I match the best batteries to my specific motor, esc and flying style? I know it sounds kinda like a nub question but this is my first 700 size heli and I cant quite wrap my head around the numbers. Here are my specs;
Scorpion Commander V 12-50V 130A ESC (OPTO)
Specifications
Max Continuous Current 130 Amps
Operating Voltage Range 12 to 50 Volts
Max BEC Output No BEC
On Resistance 0.68 mOhms
Scorpion HK-4035-560KV
Stator Diameter 40 mm (1.57 in)
Stator Thickness 35 mm (1.024 in)
No. of Stator Arms 12
Magnet Poles 10
Motor Wind 8 Turn Delta
Motor Wire 23 - Strand 0.29mm
Motor Kv 560KV RPM / Volt
No-Load Current (IO) 2.24 Amps @ 10v
Motor Resistance (RM) 0.014 Ohms
Max Continuous Current 100 Amps
Max Continuous Power 4200 Watts
Weight 460 Grams (16.22 oz)
Outside Diameter 49.98 mm (1.97 in)
Shaft Diameter 5.98 mm (0.235 in)
Body Length 61.8 mm (2.43 in)
Overall Shaft Length 100.0 mm (3.93 in)
Max Lipo Cell 12s
Peak Current 120A (5 seconds)
Peak Power 5200 Watts (5 seconds)
Motor Timing 5deg
Drive Frequency 8kHz
Now I know from reading the literature that I can use up to a 12 cell LiPo but how do I decide what's best in terms of mAh? 5000 would obviously last a bit longer, but would it run my electronics too hot? Does a single battery pack have any discernable advantages as opposed to dual 6 cell packs? My flying style is very light 3D. I usually only fly once or twice a week at the most. Any thoughts or recommendations would be much appreciated.
