The New Skywalker 1900 has been around for sometime. I just finish mine and test fly it last Sunday in strong wind condition. I barely able to trim for straight and level and P gain in stabilized mode.

It feel more or less like my old Skywalker 1900 but the rigidity of the tail section had been much improve. No more flimsy/Shacking tail boon and stabilizer.

Although it was advertise as modular/easy to dismantle and install  at field, but I doubt the durability of those orange plastic. For better reliability, glue the stabilizer and tail boom may seems a good option.

For me, the best improvement over the previous version is the enlarge fuselage. Now I can put my camera inside the fuselage with proper orientation. ( Horizontally relative to wings ). The only issue is now I had to add about 90 gram of ballast in the nose for proper CG because of the main battery sit right under the wings with no room for CG adjustment. 

A lot of user reported the left turning tendency but I didn't notice mine had this problem. Some of them suggested a twisted wings but if that is the case, than most properly all the wings should be the same because it was made in the same aluminium mold. May be I just lucky to get a good set of wings.

Nothings much to talk about the build. It is fairly simple and straight forward. I had good success with my old Skywalker so I just transfer all my equipment, i.e motor, ESC, APM 2 with 2.63 firmware to the new one. For telemetry, I use RDF900. Hopefully with this long range data modem, I'll had full connection through out the mission within a few KM.

I'll update the flight performance after I had it trim out. My flight gear as below:

Servo : Servox SH0257MG

Motor : T motor 2814-8 1000KV

Prop : APC 9X6

ESC : Hobbywings Funfly 60 A

Autopilot : APM 2. 2.63

Telemetry : RDF 900

Battery : FlightMax 4S5000mah. for motor. 2S 2100mah for avionic equipment regulated by Castle Creation 10A BEC

Were could someone buy a Skywalker 1900 ? :-)

Actually, the 2013 Skywalker is an 1880. Seemingly, only Bevrc sells it with the 1900 wings :).

Ah thanks for the infomation.

The 1880 mm wing is Got better perfomance than the 1900 mm wing. This wing Was also used on the skywalker condor version.

Bevrc having web page problems but fpvflying working great. gonna check her out

seems a nice platform for fpv and uav.

What's the flight times with a 4S 5000?


100KM

I didn't really test the endurance of the New Skywalker. But given it is more or less like the old one, I think we can expect at least 30 minutes in normal condition with 4s 5000mah

Actually flight time is very much affected by the all up weight, Cruise speed setting, motor/ESC/prop set up and weather. It will be good to monitor the voltage of the battery through telemetry constantly and set 3.3 v per cell as warning level and make sure if your voltage approach low level, you plane should be in visual range so you can call it back immediately.

Sorry, what does "I barely able to trim for straight and level and P gain in stabilized mode." mean?

I was contemplating getting a 1880/1900 Skywalker as a big platform for some video/camera gear. 30mins on a 5000mAh 4S doesn't sound like much?

Because of strong winds, it is quite difficult to trim the plane until it can fly straight and level for a reasonable distance so the trim setting may not correct. and the same go to P gain tuning.

If you want more endurance, try using low kv ( 400-500 ) motor and 12 inches prop and 6 s 5000mah battery.
