When my Typhoon H is started it emits 3 beeps and 3 red lights per second which indicates an initialization failure. I hooked it up to the GUI and it indicates a Speed Controller failure. I enabled testing on the motors and none of them ran.

All 6 props were damaged when attempting to get the drone on to the ground because the winds had severely picked up. A gust of wind flipped the drone and it landed upside down in a flower bed. The propellers and 5 of the 6 arm latch clips were broken.
The motors spin by hand and provide minimal resistance.
How do you fix this? Does the ESC board need to be replaced or just the 6 motor fuses?
Just to give an update and to hopefully resolve the problem:
1. I replaced the entire ESC board. Not a single one of the 6 motor fuses blew but several of the capacitors were damaged.
2. After replacing the ESC board the drone still didn't work and upon examination a chip in the Main Control Board was cracked.
3. I replaced the Main Control Board and everything passes in the GUI. However, I can't get the drone to bind to the ST16. Tipping the drone forward to 45 degrees twice does get the drone to go into bind mode and the main LED does blink orange but it doesn't show up under the aircraft Model list after hitting refresh.
I'm thinking that the antenna or its chip must have been damaged when the drone landed on its head after it flipped. I've reached out to the Yuneec service people and haven't received a response back from them.
This has taken a long time to get even this far. Yuneec was extremely slow in shipping parts. I replaced the ESC board back in October but there was a long delay in shipping the spare Main Control Board. We had to move onto another construction site in Texas and the spare Main Control Board actually arrived after we left for Texas. We're back in New York and I just put in the spare and now the binding problem has popped up.
We had to shoot back in October and November with a back up drone and it got damaged when a bird flew into the rear right propeller. The drone actually flew with half a propeller on that arm before the other half broke off just before I started its descent. It went into an uncommanded yaw in the counterclockwise direction before it was brought down. It went into 5 motor mode which is not as stable as you'd hope. To avoid damaging the camera I hand captured the drone. Upon examination, the arm was actually broken completely through at the attachment fitting. It was amazing that it flew like that with just half a propeller too! A repair was made by using boat epoxy. I ordered a spare arm from Yuneec along with the spare Main Control Board but it didn't arrive until after our departure.
I bought a 3rd drone off eBay to add as a backup for Drone #2 and had it shipped to the location in Texas. It was up 400 feet in the air and went into 5 motor mode and I brought it down right away. It also was not stable and was pitching erratically and I hand captured it too. It had lost half the left front propeller and the motor was extremely hot. I tested it on the GUI later and it wouldn't run so I replaced the motor with a spare I bought on Amazon. It works fine now. Also it was easier to pass the motor wire down the arm then what I've seen shown in videos on YouTube. Getting the lamp shade off the motor was impossible so I bought a lamp shade tool from one of the resellers. It's definitely worth the price!
I've also bought the composite propellers from MayTech. They wouldn't go on Drone #2 or Drone #3 but the replacement arm that came from Yuneec didn't have the propeller quick disconnect base on it but when I put the quick disconnect base I bought from the reseller on it the composite blade went on just fine. It turns out that the OEM quick disconnect bases have a slightly different slot in them than the aftermarket ones do. I've ordered more bases from the resupplier and they are arriving today and I'm hoping to fly with them either tomorrow or Saturday. Nothing flies without some testing first.
I also bought the Flight Simulator from Yuneec. It arrived with the spare Main Control Board and arm. I was able to bind it to the controller without any problems. The simulator itself is okay but it doesn't seem to do what I hoped it would. It doesn't seem to be able to send simulated camera images back to the ST16 controller. It does have value in that I can try things I wouldn't dream of doing with an actual drone and I'm sure that it would help a novice get up to speed fairly quickly without the risk of crashing but it won't do any of the advanced tasks that a real drone will.
