yeach, mine too. I just finished installed the kit and I got auw about 2.2kg with no fuel. I'm not glad with this . I remember to my first katana is got 1.8kg more than 5 years ago. easy to hover with my os 46ax. I think It's contributions of wider wing, more more weight on fuselage. so what is the advantage v2 than the first version? very dissapointing.
