H-King Composite North American P-51D MUSTANG 1200mm (47")

H-King Composite North American P-51D MUSTANG 1200mm (47")


Well, I just love warbirds, there are couple of them in my hangar, all of them are foam models.

When this nice airplane was announced , I just said to myself that I've got to have it.



To say the truth, it is not cheap plane, you need to purchase all electronics, ESC, servos, motor, propeller, battery and have your own radio and receiver. It comes with servoless retract gears which is nice surprise. But it surprised me how well built the model itself is.



Starting from the fuselage, which is made of composite material and painted extremely nice, with all possible details, over to wings and control surfaces. One minor issue is that on some spots on the wing you will need a little ironining, but that is no big deal.

Unboxing:



 Assembly


Getting it ready for flight takes some time, at least 2-3 full afternoons of work if you want to do everything right. Installation of servos take time, because you have to prepare servo mounts and glue them, glue CA hinges (yes all control surfaces are hinged with CA hinges) and do a little drilling and adjusting. And there is additional work to do, install servoless retracts which came with the kit. This is a kit which requires some knowledge about building airplane models.

Servos used for wings are Corona 929MG, you can fin them on HobbyKing.



Fuselage


Since fuselage is in one piece, there is not much to do except install servos, glue horizontal stabilizer and hinge control surfaces, but it also takes a lot of time. Of course, like on the wings, after gluing everything together, you still need to mount control horns and use supplied push rods to connect it with servo arms.

Now, after that you can install motor on provided motor mount. I had to use all spacers provided plus added some washers to set correct distance for propeller.

Suggested NTM Prop Drive 3548 1100kv which I used is worst choice possible. I only did maiden flight with that motor, and replaced it immediately, very poor quality motor which produces a lot vibrations. Here is video about that poor motor:



Don't buy it, better solution is Turnigy D3548/4 1100KV which I use now and can also be found on HobbyKing. Used propeller for this setup with 60A ESC is 11x6 carbon prop. I am flying it with 2200mAh 3S battery around 4 minutes, and with 3300mAh 3S battery around 6-7 minutes.

Servos used in fuselage are HK15148B Digital Servo also available from HobbyKing. Last part is canopy, it takes some time to cut canopy on marked line, I didn't glue the canopy but used 4 self tapping screws to fix it to fuselage



Maiden flight


I was alone at the field for maiden flight so all I could record is from onboard cam and static cam on the ground. But after one week friend of mine helped me with second flight, so I will put that video instead of maiden.

And what to say about this model ? It is sports scale model , so prepare that it is quite fast, not like foam models, but extremely stable and acrobatic. Build quality is excellent and I can suggest it to all warbird lovers.
