Thinking of Buying a 920

Once the autoland kicks in how do you override? Does it land where it took off from or does it go to where the controller is? Is the autoland feature different on the + then the 920?

I don't have answers for those questions as the one and only auto landing I've experienced occurred after I aborted a landing from low level after deciding I didn't like the location. Right after I started an ascent auto land kicked in and showed me the landing zone was OK after all... This was during one of the battery tests where i took the voltage lower than I normally would. The aircraft was within about 15' of the controller so RTH was not a factor.
 
Does DJI have proprietary 360 software? I use MS ICE for mine. Have you got the non small world 360's? The discussions on waypoints on the + vs not on the 920 seem much like the differences on the 520 vs the H+.

The DJI FC App DJIGO4 has preconfigured Pano & 360Pano, but not a clean export other than a pre-stiched JPG. The MS-ICE program isn't bad for a free toolset, but after experimenting with many free & cost photo tools for Pano Toolset the best is PTGUI Pro, available for Mac & Win. Every imaginable method of Pano's & HDR are supported and supports Raw DNG and PS files. You can control your overlap & stitch sections easily. It's not low cost at Personal @ $126 & Pro @ $253.

This is the stuff I'm looking for and the better part is you are blowing the $ to test this stuff out!;) Once the autoland kicks in how do you override? Does it land where it took off from or does it go to where the controller is? Is the autoland feature different on the + then the 920?
Haven't read through the 920+ manual, and Pat would be a better resource.
On the 920 the RTH doesn't have a auto return for battery, only auto for a loss of signal . The RTH (auto & manual switch) returns in a straight line towards direction of take-off position. Also NOTE, while in RTH, you loose aileron & pitch, only Rudder is controllable until landing is initiated at which time all controls are returned. You also can switch out of RTH anytime for standard angle mode.

Another handy function, I have not tested yet... but per Manual you can turn OFF GPS functions with the S3 switch if you enter a area that is disrupting GPS signals.

I looked at PTGUI. I've got ICE so it configures pretty well now. I use Lightroom to correct all images and export out of ICE using TIFF. If you get a lot of lines like a track then both programs have troubles stitching. PGGUI does everything for you much better than ICE.

Good to learn about lack of low battery auto return. Makes sense actually as those participating at this level should be expected to operate with awareness of the need for "fuel" reserves for operational safety. A legal requirement in full scale operations, both private and commercial. When this system first came out it cost over $7k, which is not a price point the reckless and fool hardy would normally participate in. As prices have fallen considerably in order to clear them out they have achieved a price point relatively equal with systems where user routinely demonstrate reckless behavior. This is cause for some concern as the 920 is absolutely large enough to cause a fatality or serious injury should one strike someone. The props themselves can be lethal.

I have not had reason to explore the very low battery auto responses, nor bothered with the RTH switch, but can confirm GPS can be switched off on the 920 Plus in the same manner it is done with the Typhoon H. Max flight speed increases with GPS off but not substantially. I don't know if I was dealing with an optical illusion because of size differences but it seemed the 920 experiences a little more drift velocity than a 480 in the same amount of wind when GPS is turned off. That may have been an illusion or fact due to increased "sail" area. No big deal either way.

As for flight modes, I've only flown in Smart mode one time, briefly, and found it functions the same as the 480.

There are some nice features of the Yuneec's FW on FC's. When you popup the dialog box to turn off GPS, it stays up so you can revert settings or continue to experiment. Other FC's once you make a selection it fades & clears from screen, meaning you have to hunt it back up a 2nd time while watching the AC.

I've seen several H480 videos testing GPS ON / GPS OFF fly by passes. It looks like it can easily get 10 mph faster based on ST16 screen with GPS Off on average.
I'll test the 920 in Spring, Interesting what the big bird will do Off / On since it wasn't designed to be agile.

Got a couple UK guys that have tested top speed on the H with GPS turned off. Closer to 50 MPH from what they've reported. Pretty quick in my opinion for a 480.
 
Opps, one of those knew it, saw listing and focused on the wrong one. Hopefully you didn’t order yet.
Short; xT90 male to EC3 Female

The short no wire adapters are a “No-Go” for fit.
They’re actually a connector with 1/4” wire between under the heat shrink with a little flexibility. But not enough to make it a workable connector.

Don’t bother purchasing the short connectors.

As hard as it is to insert the pins and lock them into an EC-3 connector body when you have an inch or more wire flexibility to work with I can’t imaging how much more difficult it would be with only 1/4” of wire. Gotta be a cast iron beatch.

I've come across several old reviews & advertisements where their tests show the H920 (original) normally was rated at 48mph. For a big bird, that's moving! Now the reviews didn't indicate GPS off, so assumed on. I've also come across a few video tests where they've compared GPS on vs GPS off... and obtained ST24 indicated speeds of 48-57mph with GPS Off.

How come u always gotta be a wet blanket?
That won't happen with a 920 Plus. The conversion reduced the max speed to roughly 25mph.
 
I try real hard not to lie to or mislead anyone;) The speed limit on the 920+ is one of those things I'm still trying to figure out. As the batteries, motors, and props are the same for the 920 that speed limitation has to have been incorporated into the firmware, FC set up interface, or via an ESC limitation. Perhaps it's something that can be bypassed or "corrected".

Completely agree... not enough finger or probe room to lock in connectors.

Since the stubbies won't work (never do :rolleyes:), had a place give me a quote to make 4 leads XT90-EC3 and was shocked by their cost... wanted like $92!! :eek:

Well that spurred the motivation to setup the soldering bench. Was looking up the connections to purchase when I had a dah-moment... if I'm making connections, why not just change connections on the LiPo's. I've got some EC3 on the way to just change leads.

You’ll be hard pressed to fit tinned battery wires into an EC3 bullet connector[emoji6]. Solder splash to the outside of the bullet prevents them from being secured inside the housing. It can be done but...

$92.00!!?? Think I need to revisit my pricing structure[emoji56]
 
Pat and Doug, for once I won't ridicule either of you. I had previously asked if you guys were putting the conversion connectors on the batteries. If this is what your suggesting then do you take them off for charging with the 920 charger or some other alternative?

Since I don't have the 920 hear until tomorrow I have to make assumptions. Pat are you saying that if we put a non-wire adapter then we'll have a hard time making a connection to the connector in the 920?

Sorry for the novice ?'s but it's hard to visualize what the issues are.

Hey R U reneging on the $12?:eek: Whatda think Doug, should we trust him anymore?

The connections are whether to use adapter leads or change the LiPo Lead-Ends.
The adapter leads is a short 2-4" set with XT90 on 1 End and EC3 on 2nd end.
The H920 battery chamber receptacles are EC3 and the LiPo Battery Leads out of the Box are XT90. Thus the need for the adapters... interface between the two.

In the above chatter... I was indicating to remove the XT90 from the LiPo and replace with EC3 connectors, no longer needing adapter leads.

I personally don't use the H920 Charger, but it was made to accept Yuneec batteries with the EC3 connectors. If you use the H920 charger with the Zippy LiPo's you'll need the adapter leads to interface in same manor as the H920.

I'm pretty sure I understand the issues. If you convert the leads that are on the 920 then you have issues working around the batteries with the non-wire connectors. Pat is making wired converters that allow you to snake the wires around the battery. If you convert the lipo's then you either need a converter for each battery or unplug and move to each battery which could lead to worn out connectors.

Is this a fair assumption? I'll leave it to you guys to come up with the best solution. Tomorrow is suppose to be a heat wave so hopefully I'll have the 920 here and can start playing.
