Yuneec Typhoon G.
Up at Lake Tahoe California.

Things going well until trying to land.

Then accelerated decent again.

Tried to land in Angle mode.
I never use HOME any longer trying to land it.
I will use HOME trying to bring it back to above

- - -
Here is the video. it is pretty cool. Until the crash


- - -

I have some more air frame damage.
An old crack opened and a new one started.

Time for more JB weld

Three props broke.

I still want to fly so I had two Yuneec props on hand
and a third prop which is fiber glass.

Maybe this will get me to ditch this air frame and move all the parts to a new one.

I am getting the red light flashing and the tones upon turning on the Typhoon G now.
So I must have broken an ESC board? Or damaged internal electrics. There is not much to damage in there really. I don't think the main flight CPU board can be damaged easily by a crash.

All my clear reflectors below the motors are cracked from multiple crashes.

I really wanted to get a few more videos up here. But not going to happen,
Too hard to fly it up in the mountains.

Landing it at altitude is way too hard.

I don't think it has to do with altitude. I live at 5800' and fly frequently at 8000' ft with no issues. I've got another friend who has a Q500+ and has flown above 10k feet with no issues. So, I don't think its altitude related.

Could be the ring vortex "thing" if you were coming straight down. I couldn't tell from the video. But I don't do that I always move around like descend coming down in a circle, basically "flying" down....

I have seen the bounce happen.
I just bring it down in Rabbit then move to Turtle mode.
I will hover it and catch it with my hand and turn off the motors if I can.

If I have to land it on a surface, I go to Turtle speed mode and then force it to land by keeping the stick simply
down to keep it going down.

As soon as it is on the ground - cut the power to the props.
If a gust of wind tips it when landing then at least two props will break.

I am really thinking about a more unbreakable drone now.
One that I can crash and it will survive my mistakes.

The Gimbal has survived ALL my crashes so far.

The Gimbal lost a round cover on the last crash but is still working.
The Hero cam interconnect wire has snapped three times and I keep soldering it and using epoxy.

I have NOT found a replacement video wire to the hero 4 cam from the 5ghz transmitter yet.

My Yuneec Typhoon G will now not pass init.
I get the flashing red light.

Guessing that an ESC has broken on the crash landing.
This would be the 2nd time I have had an ESC fail due to a crash.

I don't have the terminal USB cable up here, or a spare ESC or a soldering IRON.

Does not matter. We have high winds and snow for the next few days.

OK well.
Got the Typhoon G back home.
Took JB Weld to the frame.
Replaced a blown ESC board.
Bought 4 new props.
Good to fly again

How to fix if you can't pass INIT and you get the flashing red light and the tones.

After I crashed on the dock in Tahoe, I could not fly again as I did not have
the USB cable with me. I did not have a spare ESC with me or my
soldering station and solder.

Did not have props either.

So I went thru this sequence to fix the Typhoon G
starting with liberal application of JB Weld again.

All right then.
Got the Typhoon fixed with JB Weld Epoxy.
Put on the Maytech props (which are said to fly off due to bad threads).
and had three successful fights.
Two over the ocean.
Half Moon Bay California Ritz Carlton Hotel

Did NOT crash. Did NOT crash.

Gateway to Cape Cod
The latest updates to both the ground station and the airframe firmware help tremendously with the bouncing landings. Almost totally eliminated the bouncing.

Vortex ring state will happen only if you land faster than 300fpm with a tailwind. Be mindful of wind direction and if you have to land quickly do it into the wind.
