    I have recently had the opportunity to get this Heli and put it in the air. The packaging it comes in is absolutely stout and this should arrived unscathed despite any shippers attempt to destroy it on its way to you. Assembly is minor just attach the blades using the included Allen Wrench, I would recommend using it so you don't to strip the plastic! The Heli comes with a spare set of Blades, Main Gear, Tail Blade and a small Phillips Screwdriver.

    The biggest downgrade is the manual, Yikes. We are working to get a better version of it soon but for now the Throttle and Pitch Curves work and a general understanding of Heli programming may be helpful. The Flying part was the best. I have flown Helis for a few years so I was ready for anything. In 6G it will not allow you to roll or flip the Heli but you still have to fly this thing. Do not let the 6 Axis Gyro fool you into thinking it is an Auto Pilot cause it's not. Is it a stable Hover, Yes but you have to maintain it thru stick inputs otherwise it will stay level but drift off on you. Can a Beginner teach themselves with it, Yes but one needs to have patience and not get ahead of yourself. Stick to Tail In Hovering first then graduate to flying simple circle patterns working up to Nose In Hover.

    Flight times are in the 3-4 Minute Range and the RTF Radio is more than adequate to do the job and I recommend the RTF if you are new to Helis. As always feel free to call us to get more in depth information and we will gladly get you taken care of.

      If I have the transmitter for the K124, can I put this model on that transmitter as well? Or the transmitters can only hold one model at a time?

        Yes, the XK X6 transmitter that comes with all the XK RTF helis has 10 memories (and all their helis use Futaba's S-FHSS protocol so they can all be flown using the same Tx).

            Just received my XK K123 micro heli, have a question. the TX comes preprogrammed for the heli, however what swash plate do I use. I changed to 120* and it seemed to fly better
            is this the correct one to use or put it back to factory. Still need to trim it a little, but I like it.

              No, don't use the 120° swash type - the one you want is the factory (90°) default. Even though the swash (on all XK helis) does indeed have 120° geometry, the cyclic and collective pitch mixing (CCPM) is actually done inside the Rx/FBL (flybarless unit). The CCPM mixing is not done inside the transmitter.

                Thanks for the info. went back to 90*, fly's great after setting trims.

                  I am having some trouble with the gyro on my K124. At times it pulls in a certain direction, mostly to the forward or backward direction and I do not have enough swash throw to counter it. Why does this happen? Does it matter if its on 6G or 3D mode? Since the explanation in the manual is really confusing on how to re-calibrate the gyro, I would like to know what every does in calibrating? Do you calibrate in 3D or 6G mode? I have been flying helis for a long time and have all sizes, from scale to pod and boom. I must say these little guys have really hit the nail, except when they start acting up and have a mind of their own.

                    Thank you - I don't check this forum much but looks like I will be from now on :)

                      After six years hovering micros indoors, I recently started going outside and trying my hand at inverted flight. (I moved from the city to rural central Utah last summer so I now have a flying field in my back yard!) My current favorite micro is the XK K123.
