3). Highly efficient bevel wheel design is used in mesh between main gear and motor gear (except 59# and 60#).
4). 59# series' tail blades driven by axis provide easy adjustment, stable flight, and prompt reaction.
5). 60# series' tail blades driven by belt provide easy adjustment, stable flight, and low noise.
6). 380 carbon brush motor, matched with 20A brushed speed controller, provides more power to your helicopter.
7). 7-ch transmitter PCM701 with adjustable PIT parameter, throttle curve, and servo exponential function.
