FPV Flying Wing Build

FPV (First Person View) if you don’t know is probably as near as you can get to real flying without being in one of those big simulators costing lots of money.  Basically you can see what the model is seeing (if it could see!).

I did try the FPV gear on my smaller flying wing http://www.rckeith.co.uk/hot-wire-cnc-ymf-38-flying-wing/ which I built as a first test on my CNC machine.  But it made it very unstable so hence I’m building this wing.

This  CNC build of a FPV flying wing, very similar to the RiteWing Zephyr II which is very popular.  The middle section will house the electronics.  Its made from XPS foam which I get from http://www.wickes.co.uk

I’m using a small LCD screen with a shroud before I decide to buy  Fat Shark googles.  I need to see if I like this type of flying.  The FPV gear I’m using is all based on Bruce Simpson RCModelReviews youtube channel recommendations.  He’s knows his stuff.

Camera is http://www.securitycamera2000.com/products/600TVL-SONY-SUPER-HAD-CCD-D%252dWDR-Color-Board-Camera-with-OSD-Menu-DNR.html

Transmitter and receiver are from Foxtech FPV http://www.foxtechfpv.com/ts832-vtx-rc832-vrx-combo-with-raceband-p-2125.html

Maiden Flight

Maiden flight of wing was without FPV just to get it trimmed out, and whew it was very lively until I got the throws and rated dialed in.  The motor I selected was a bit under-powered so I updated this for 3528 1400KV which was a lot better.  Second flight was with FPV powered up but not using the diy googles just to test the picture was getting back OK.  Third flight I took off without the googles on and then got one of my club mates to take over the controls while I got use to watching through the google.  After a couple of minutes I took over and it was a bit scary and I didn’t last long.  Wing was a bit lively so added a Hobbyking gyro  the OrangeRX RX3S 3-Axis Flight Stabilizer to get the wing more stable, before the next try.

Crashed it

We’ll the gyro didn’t work very well and caused the demise of the wing.  First flight with it felt strange and so I decide to land and turn all the gyro pots right down so they would have no effect.  On the 2nd launch the wing went off OK for about 30 feet and then just did a nose dive into the ground for no apparent reason and destroying the wing.  Luckily the camera and all the electronics survived.  Not sure if this gyro was faulty but I’m going to try it on my Extra 300 park flyer http://www.rckeith.co.uk/ex300/ and see what happens.  On reflection I don’t think I got the design right to suit FPV, I had to add a lot of lead to get it to balance.   I will build another but I think I will add more sweep to the wing.  Anyway I now have the Hobbyking  EPP-FPV http://www.rckeith.co.uk/fpv-plane/ which should be a better option for my FPV adventures.
