HM 4F200 is a very unique tri-blade Collective Pitch(CP) rc helicopter. Besides its Tri-Blade Rotor, even its tail rotor is in tri-blade as well. With its 3 blades, which have greater torque and very resistant to change in direction. Together with the 3 axis gyro, you will see how awesome is the stability of HM 4F200. Such powerful design usually put on real helicopters, 3 blades in collective pitch imply it can change angle and generate larger lifting force in a shorter time. So, you can imagine it has move very quick in response to your thumb.
Tri-blade 4F200 is as unique as other multi-blade helis, because of the unstable condition with the absence of flybar. Computer system is required to monitor and adjust the movement of radio control helicopter in order to stabilize it. But now, Walkera has made it real by transplanting a 3-Axis Gyro on this 3-blade rc helicopter, and equipped a fully programmable Rx-2612V which works with Tx-2801 Pro. 3D aerobatics have been able to perform after some tunings of pitch curves and throttle curves. Without dampener even makes the bell rotor head much sensitive.
As you see this heli is fully equipped, it may not be the best choice of totally-newbies. As you have to tune the pitch angle for 3 blades, certain degree of understanding on pitch curve and throttle curve. However, HM 4F200 not bad to be the next challenge for co-axial pilots.
Someone flied this heli already said it is stable in hovering, impressive fast forward flight, smooth action, solid tail in full pitch climb. From a video, it show that it can fly under quite strong wind. All and all, it is an amazing small 3D outdoor helicopter.
