Good vertical climb ! 3 S 2200, 41,82 Amps, 10,71 Volts, 460 Watts with 10 x 4,7 prop (max size possible for this motor). Motor fits perfectly.
Stock motor is crap
... Gear too
. Made a solid one with 2 mm alu : very strong, then the fuselage broke
under trailing edge at first landing. With spruce longerons inside fuselage now it's finally OK.
Very good flights with 20 grams lead in the nose.
Throws : MAX with 25 % expo.
Paint : the original blue is a joke... paint it black !!!
HK should pay attention to some of it's products quality
