UAS Build, Airframe HK FPV 168

Posted by UAS_Pilot on March 15, 2012 at 6:30pm

Well I just recieved my FPV 168 from HK.com. The only damage I was able to spot from shipping was the tip of a horizontal stab. Here are my plans for the build.

I want to have a pan and tilt camera hanging on the underside of the fuselage. I bought the pan and tilt system from ServoCity. I got 2 continues rotation servos. My second payload will be a 12 mega pixel still camera to take pictures of the ground for mapping.

The telemetry is using a 2.4 GHz with a 1W amplifier on the ground xBee.

I have allot of planing to do to get it up and running. Still awaiting all my parts to start the build. I will keep pics coming once i get started.

Not the problem. It was the video 900 MHz. I have flown another plane with. The same set up minus the 900 MHz video and no problems for 3-4 months. The 900 MHz video at 800 mAh swamped the specktrum Rx and locked out the Rx. I had the antenna too close to the Rx on the plane. Completely my fault. I have a new plane now and will test 1 step at a time. I should have had my fail safe for the radio system to rtl not manual. I also have changed the Tx to utilize frsky 2.4 Sys freq. hopping to avoid a repeat. Specktrum find a freq and stays with it no matter if it gets interference or not. The frsky will change to another open freq to avoid a lock out. Many test flights in the future and I will keep you all informed on me findings.

Sorry to hear that mate!! Thought it was going to be a winner with your set up. With this hobby, there is always a failure mode waiting that comes to the surface.

Have you thought about that big black Flying wing that is on HK?

You would need a launcher of sorts, but looks like it has a very big bay.

Well the UAS 168 did not make it. My JR 9303 and AR 7000 stoped talking on the 2nd flight and down she came alsmost in slow motion. Everything else worked great, Motor, ESC, Batt, Plane, But the Radio gave out for the first time ever. I even did a range check following all the Recommendations from JR.

Oh well *#@^ Happens... Its all part of the hobby. Looking for a new airframe now thats not on backorder.. any suggestions?

Sorry I am unaware of the empty weight, nor the full up weight as of now. I am planning on weighing soon. I hav completed the build and I will have some new info on the site soon. I have not maidened it yet as I have just completed it today.

I will get some pictures soon and some flight info.

Looking like a fun build. Would you happen to know the exact weight of the airframe as delivered from HK? As usual the sight does not give the actual weight of the aircraft.

I have been thinking about one of these airframes as a FPV aircraft, but wanted to do some wing load calcs before hand to see what it can carry.

I finally recieved all my parts from China.... Yeah...

Now the install of all my gear will begin.

I will add more pictures as time goes on.

I am sorry for the dead space on the build.

I am awaiting parts from both china (HK.COM) and from mexico (UDRONES.COM)

I have decided to put together a tracking antenna because I recently found out from Oborne that the v1.1.55 of Mission Planner now supports Antenna tracking. This is a great addition to a great GCS. I will be able to maintain link with the plan at much greater distances. I am poking forward to testing it all out once it it put together.

I will start providing more updates as soon as all my parts arrive.

I have received my turret gimbal. It has 2 continuous rotation servos. It move very smooth. It does not retract but it should never touch the ground. ;P

Still awaiting all my other parts to complete the build. Slowly but surely I will get it complete...

Latest update on the build.

I have the servo wires route in the wing and in the tail. I mounted the Pitot tube in the leading edge of the wing and glued the wings together. Once my electronic show up I can start mounting everything. I should have the pan and tilt gear this week and hopefully by the end of the week I will have my motor/servos etc....

I have a few pics to see the progress...
