Fly stable and easy to control, ungentle landings are well cushioned. But the little one is too sensitive. Charging via USB never worked properly only on the remote control. The on / off switch at the Pebble is extremely tiny to detect the charging contacts hardly, you are constantly afraid to bend slightly. After several flights then the board was moved to the switch and the charging socket and probably had a loose connection. We now have a comparable Hubi from Carrera with metal chassis, looks much more stable.
