Default Align 470L low head speed result

Specs:
Align 470L with stock blades
Scorpion HKII 2520-1580
11tooth pinion.
Hobbywing Platinum 60 ESC.
Turnigy 1.55 6cell lipo.


I run at 2000rpm very comfortably with plenty of tail performance.
I can get > 8 minutes of sport flying down to 80% on the battery.
All component are just warm to the touch after the run.

I will try to find the lower limit on this setup and report back.

Stock motor and HW 60a 6s 1800 I'm getting 1603 rpm at 50% throttle curve. With the HW v4 ESC I find RPM stays the same on a 3s 2100 (if below around 60% throttle).
Tail holds nicely as long as your carful even during fast inverted backward circuits. Just don't expect to do tic tocks on 3s.

After a 5 min flight only using 700-850ma out of a 2100 3s.

Had a lower rpm with 15 deg of pitch but to easy to loose the tail. Went back to 12.5.
