This is my experience with this little helicopter:
Buyed it this week, about ten flights of 8 minutes average (last minute and half of flight it just can barely hover in ground effect ) using the stock 600 Mah Ni-Mh batteries.
DidnĀ“t touched any setting of the heli, with the exception of the ciclic elevator and aileron swashplate throws, the pushrods are factory installed in the outer hole of the servo arm, I installed it in the middle of the servo arm, it made the heli less twichy and more suitable for indoor flying.
ItĀ“s a good idea to make regular checks at the main and rear motor mounting screws. they like to get loose. be careful to not overtighten.
I buyed a second battery pack, and slow charge them using a common Ni-Cd cycler at 50 Mah, for 15 hours, so every night at home I have guaranteed 16 minutes flying without being worried about burning down the house
Overall it is a fun indoor experience, I will try to fly it outdoors in the club this weekend in the late evening, when there is almost no wind and no light enough to fly the heavier stuff. IĀ“ll post my results here.
Best regards, Enrique
