THANK GOD,
i found this article at your web page!, (Silverlit Toys Manufactory Ltd. - Flying Club) recently( before X-mas)
i purchased what claimed to be a Silverlit PICCO Z , from hobbytron.com and when it arrived i was confused because the box read (PICO Z) and NOT PICCO Z nor it had any trade marking of Silverlit on the box..
I ended up opening it and it was terrible, the helicopter is uncontrollable, it does not trim correctly, and in flight it just spins out of control then nose down, I have tried modifying it using the aluminum weights it came with, but no luck...I took it to a local hobby shop and concluded it was NOT a PICCO Z, but a "counterfeit knock off".... i was very, very disappointed.
I tried to contact hobbytron through emails NUMEROUS times, if I can recall 7 emails. and after about a months period of forwarding emails NO response at all.. IF it helps the Email i sent to hobbytron.com AND receipt i got from hobbytron.com is below, claiming i purchased a PICCO Z , when in reality I received A "PICO Z".... and till today i havent got to a response or the experience of flying a real picco z
