Richard Ward-Davies Posted January 17, 2017 Share Posted January 17, 2017 Hi Everyone,I'm having problems with my Hubsan Spy Hawk. After an unsuccessful flight today which ended in a light crash in long grass. (No physical damage) I returned home and went to perform a system check. I switched everything on and the plane binded quickly to my tx but then I noticed the port side aileron start twitching. Then it stopped working all together. Then the monitor on the TX froze. I switched everything off and then turned everything back on to find that the aileron has stopped working all together. So has the elevator and the screen on the TX is now black. The grass was damp today so I'm hoping maybe some moisture has got in and it will work tomorrow. I'm clinging on to that hope. Anyone had any experience of this? Thanks Richard Quote Link to comment Share on other sites More sharing options...
Richard Ward-Davies Posted January 18, 2017 Author Share Posted January 18, 2017 Update... Servos now working again?? Camera still blank. Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted January 18, 2017 Share Posted January 18, 2017 Reading the manual Richard, the camera module can overheat, if the plane is not moving and cooling the unit after 2 minutes and the screen can go Blank. Check there is cooling, and am afraid you cannot just leave the unit on without flying Incredibly, after an arrival, maybe 3 minutes walk from you, then the unit will have overheated?

Richard Ward-Davies Posted January 18, 2017 Author Share Posted January 18, 2017 That could be it. I'm wondering if it resets after a certain amount of time. Thanks for the reply Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted January 18, 2017 Share Posted January 18, 2017 It does reset when cooled off. Am afraid you cannot have the gear switched on idling any length of time, just be ready to launch after switch on. Do not be rushed, do all your preflight checks, and launch Quote Link to comment Share on other sites More sharing options...
Dave Bran Posted January 18, 2017 Share Posted January 18, 2017 Newcomers to FPV do not generally appreciate the temperature that a FPV Video Transmitter can quickly reach, I know I didn't! In my case the realisation was nearly being burned by the aerial and that was with a quad FPV all PCB, etc, exposed to air. I had one mini quad where the combo aerial was dislodged, and swung back and down to perfectly short the main flight controller PCB supply. On checking I found the FC board working (well it would as its supply had been removed!), but the camera combo was "dead". On further checking I found that the main supply wiring to the combo had acted as a fuse and had melted apart inside the cable insulation, so quite a current had passed! I rewired it, and it worked and works to this day, so you might well get it all back OK. Quote Link to comment Share on other sites More sharing options...
Dave Bran Posted January 18, 2017 Share Posted January 18, 2017 Oh, and it may be obvious, but bears repeating, never ever turn a VTX on without an aerial load, as she'll noo tak the strrain, Captain Quote Link to comment Share on other sites More sharing options...
Richard Ward-Davies Posted January 19, 2017 Author Share Posted January 19, 2017 Thanks everyone. I'll order a new PCB board. Harsh lesson learnt. Quote Link to comment Share on other sites More sharing options...

Are you sure it has gone ? It could be a wire burnt out check first. John Quote Link to comment Share on other sites More sharing options...
Richard Ward-Davies Posted January 20, 2017 Author Share Posted January 20, 2017 Checked wires. All seem ok. Camera ribbon seems OK too. I'm a bit worried about inserting the ribbon into the new pcb board. I'll update when it's done. Quote Link to comment Share on other sites More sharing options...
Denis Watkins Posted January 20, 2017 Share Posted January 20, 2017 Obviously Richard, connect up with no battery connected. Tether the model for brief checks. Have correct movements rehearsed in your mind so that you can quickly see correct sense on the model to stick movements. The stabilisation arms automatically, but give that a fair chance by having the model level at start up. Quote Link to comment Share on other sites More sharing options...
