Hi there people
maiden flight time for this little helicopter then! The weather wasn't super but I just Had to get it flying

Here is how that went...

I did got one some time ago from HK. It seems that my one is not 100% ok: it does seem a bit loud. the flight time is not exceeding 5 minutes (very slow/steady flight) and the battery is "very warm/moderatelly hot" after the flight. Maybe some part of the drivetrain creates too much friction and thus qualifies for replacement; but I'm not the helicopter expert and didn't have time for proper troubleshooting.

Besides that, the heli flies nice and after several minutes of stabilized flight I could safely switch to acro mode.

I can confirm those findings.. Flight times are on the short side.. And the lipo is WARM after that.. From others I've heard that the lipo's won't live very long..

Mine seems to be getting a bit less noisy now.. Maybe the gears needed soms running in.. But it's not quiet by any means..
