JYU Hornet S


Hello !
I see here is much good information about JYU hornet s.
But I can not find my problem.
It begins with that the drone dosent always get green light. Only some times. And when I try to fly it immediately get ted light and want to land.
And I try and try but now the drone donít get green at all only flashes fast red.
Do someone know what can be wrong?
I search every ware and I do not tone what to do.

I have basically inherited a couple of Hornet S's and spare parts. My manuals and Tx markings are all in Chinese. I downloaded the English manuals from JYU.com and used a P-Touch to label the Tx controls. I've got the Hornet and Tx charging so I'll surf through the manuals to see how big the learning curves going to be.

Any advice for a Hornet S newb?

How do you guys transport your Hornet? I have a Hornet backpack and all the OEM boxes.

In my pile of Hornet S stuff, I have 2 batteries and 2 chargers. 1 battery is at 2 charge lights, the other has 3. When I plug either batter into either charger, the green light stays solid for about 2 seconds then starts a flashing red warning to unplug it. Only one of the chargers beeps when the red light flashes, so that's probably an issue with that one charger. The order of plugging in the battery and wall outlet does not make any difference.

Have you guys tried replacing the cells in the battery case?

Edit: Finally figured out that you have to turn the battery on with a short press & then a long press of the on/off button. Now seems to be charging normally.

Yes Agree with Sebydocky, Possibly Damaged Battery as i had one like That a while ago. Charges up but does not last when load is applied, goes red, flashes red shortly after takeoff.

I'm Thinking you have only one battery so you cannot test with another battery.

ANd as i said always make sure your Hornet s has the latest updated firmware, which has been working fine for me for a long time, if will reduce the software glitch fly aways that happen to several hornet s in the past.

Yes Lots of mods with Batteries has been done ive even done quite a few., but to be honest the stock battery that comes with the Hornet s is the best to power/weight/discharge for the hornets and it locks into place nicely and flies the way it should.
You Just need to buy a few extra batteries when there on sale.

Type of connectors


Could anybody be so nice and tell me whats the name/type of these connectors.
It is my GPS cable, which have gotten trapped in the frame when assembled.

TIA

After having changed the cable to the GPS module, there is still no flashing light in the GPS module, neither does the four GPS leds under the motors flash?
When I turn on the quad, the acustic greeting are heard, and it does bind to the remote control.
Would the leds under the motors flash even if the GPS module is dead/disconnected?
Any suggestions are welcome.

BTW everything worked before I put the shell together, so it does not fail due to a crash.
Can't see any damage wires.

Could the GPS module been fried from the faulty cable
