Small EDF ordered

I recently found this cute little EDF and just had to get it. The plane is only 660 mm wingspan with a 40 mm small EDF. It requires 2 micro 2,5g servos to control the two ailerons/elevator.

Tech specs (HK info):
Wing Span: 610mm (24in)
Length: 390mm (15.3in)
Flying Weight: 140g
EDF Unit: 40mm (Required)
ESC: 15A (Required)
Servos: 2 x 2.5g (Required)
Battery: 2s 7.4v 500mAh Lipoly (Required)

EDF Unit: 40mm
ESC: 15A
Battery: 2s 7.4v 500mAh Lipoly
Servos: 2 x 2.5g

I got the EDF 40 completely assembled with a 8400 KV brushless motor, which should fit perfect. It can only handle a 2S pack, but I'll try to find another motor for better performance.

Tech specs (HK info):
Weight: 28g
Kv: 8400rpm/v
Size: 42 x 39mm
Battery: 2~3S
Voltage: 7.5, 8.0, 8.5V
Current: 13.0, 15.0, 17.5A
Thrust: 130, 150, 170g
Watt: 97.5, 120, 148.8W
Efficiency(g/W): 1.33, 1.25, 1.14

As soon as all parts arrive I'll do a build log and a test run.
