Hi All,
Looking for help and advice! Would appreciate your comments and tips.
Here there is my story: I had flown 4 batteries today without any problem: taking off and landing were smooth and nice each time and especially the later ones never were hard. I put the 5th battery flew the bird yet again without any problem and finally set off to land very last time. To my great supprise one of the landing gears (legs) did not lower. I would play with the landing switch 2 or 3 times without any help - the leg would stay at its upper position. I thought that the only option left would be to perform a hand-landing. So I would lower the thing so I could reach out for it with my hand and then would press red button on ST16S to disarm the engines. All for vain. The button would not turn the engines off.
I hope you can imagine how desperate situation I was in - one leg down the other up. How to land safely for h520 and its camera?
Fortunately as lucky as I was after giving it another few tries the leg, step by step, went finally down.
After landing the bird I would notice that the leg in question was not stiff at its lower position as the other one. It has a little degree of slack.
I tried to see whether the problem would persist so after taking props off I pressed the red switch on, the engines started to spin and the gear was not working. Unfortunately h520 didn't turn off neither in response to the red button nor the drone power switch. Had to lift it a bit from the ground and sit back to get the engines stop.
So now I would appreciate your comments and advice on:
Has it happend to anybody, have you heard of such/similar situation before?
Looking forward to hearing your comments,
Pawel

So now I would appreciate your comments and advice on:
- what to do - send the h520 to the nearest Yuneec service which is Germany? Or ...?
- how to safely land the bird when the engines don't respond (stop) to the red on/off switch on st16s? Is there any other option to hand-land when sth goes wrong? I can't recall manual would give any instructions on this.
- is it normal that the red button fails to switch the engines off when the drone is say 2 m ATO? Will it turn the engines off at all when the drone is airborne at low altitude?
- is it normal that the engines start without props on? I believe I read somewhere that they don't, but I might be wrong.
Has it happend to anybody, have you heard of such/similar situation before?
