... And after MCX2 and the MSR followed by the 120 SR (BNF because DX6i is available). This sequence is actually "normal" and the SR 120 is basically a big MSR. In the living room with plenty of open spaces is alledings also much more than hovering barely possible, the real fun begins outside. Quality must be the default 120 SR compare with a clear conscience with the aforementioned. Even the consumption of spare parts will have to be limited - just as long as one takes into account the larger footprint and just in case time turning off the engines. I have after pairing with a DX6i (setting area not Hubi, ranging as FP) can use it out of the box float immediately clean easily. Only fix off the ground, yet easy to steer to the right, as right-handed Hubis happens to naturally drift off to the left at the start. Not necessarily suitable for beginners In my opinion, some experience with a coax or a housefly as the MSR should already be available.
