Why does my Picco not trim properly?
– When trimming your Picco Z make sure you are pressing the directional key in the right direction relative to how your Picco is rotating. If you have done all you can in this respect, try straightening the tail shaft out gently with your fingers to ensure optimum tail rotor performance. Also, ensure your tail rotor blade is not damaged or cracked. If needs be, replace it with the additional blade that was included in your packaging. Also do a quick check of the tail rotor for any hair or string that might have gotten wound around it which would cause it to not spin properly.
