URGENT: Tighten your props with wrench

mad in nc, how do you access the data you 1st mentioned above? I have been involved in so much other stuff I missed out on how to do that.


DJI in 4Q last year published the SDK (Software Development Kit) for third parties to develop apps....
Lvl 1 - GPS, Telemetry and camera
Lvl 2- complete access to operating system for control (i.e. follow me program development as an example)

.... and I'm not going into the belly of these beasts to figure it out :D

That's a lot of info posted. Apparently I took your original post all wrong. You gave me the impression that yorlik was using some part of the sdk to read his .csv files after a flight. I obtained Lvl 2 access and downloaded my own copy of the sdk last year when the option became available. Since I'm not a software developer I did not spend a lot of time with it. I knew of some that could use it that at the time did not have the level 2 access and I had planned to allow mine to be used so we could get under way on getting new stuff developed. They opened it up to everyone around two weeks into it.

So anyway....kilroy I mean yorlik is actually just using the flight logger that Ken has. Btw, I haven't mentioned it but Ken and myself has been the two working on his flight logger in between when he himself works on the other parts of the app. When you get version 1.61 the flight logger should work at about 95% now. The flight logger part is almost finished. The few columns that are not working are waiting on dji to fix with in the sdk. You can also blame me for pulling him away from other parts of the app. But that will soon change as I said the logger is almost complete. Reordering the columns is the largest task remaining on it. Ken adjust the formulas on several columns early this morning which a few may be still off some. I will do a test flight soon with the v1.61 and see where things are at. Thank you Ken for getting it to the level it is now.
 
I used my supplied wrench on my v2p about 6 times when I was trying to land via CSC before learning that is a dumb way to shut down. Yes, the wrench fits well (just come down over the top of ridge, not straight into it from the side as it is triangle shaped).

Better than explaining would be to point to the detailed work Paul did showing how the pre 2.1 units were electronic fuses:

In recent discussion with Paul, he confirms the 2.1, although same hardware, do not blow FETS like that anymore (firmware update fixed it).
Please explain how CSC is a dumb way to shutdown? What do you suggest is proper shutdown? Left stick down?
 
Is this on all Vision Pluses?

I'm not sure dumb would describe it but CSC, many believe, if for emergency use only mostly due to the instant nature of the shut-down response.
When using it after landing some people have experienced issues likely caused by the directional controls which are part of the 'pattern'.
Once the a/c is stationary left stick [only] full-down will shut-off motors in about 3 seconds without the risk of the Yaw, Pitch, and Roll inputs causing unintended operation.

HeisenbergAR15, a CSC can be used to shut down the motors, but it's not preferred way since it's hard to cleanly do. If you do not put the sticks exactly in the corners, the motors will accelerate briefly -- which often causes the Phantom to tip over. If that happens, you will most likely damage your props, ESCs, and/or motors.
 
I find that if you perform the CSC exactly as described in the manual as shown above, the CSC works fine to shut down the motors. You need to have the throttle full down before you do the CSC. If you try to do the CSC without the throttle being completely down first, that's when you will have problems.
 
Why chance it though? Holding the throttle down to shut down the motors will never cause the Phantom to tip.

What if a child runs up to it as soon as it lands?

Maybe it should be used only when needed, but known by all. ;)

It shuts down just as quickly by holding down throttle than CSC. Not much of a difference anyway. If a kid is close enough to run up to it you are not being responsible anyway. Just dont land around dumb kids who dont listen. I agree that using CSC when landing is risky because of the possiblility of a tip over. I have never tipped over using the the throttle down method. I mostly just catch it in my hand to land now anyway. To me that is the safest way.

3 seconds is a long time when a child is running.

I'm not trying to tell you what to do. No reason you should think I am irresponsible either. :p
 
A child running towards your powered on Phantom = Time to activate CSC and risk damage :)
 
IflyinWY, I hope you're kidding about landing your Phantom around children. That could be extremely dangerous.
 
Jeeze,

Do what you want.

The pros/cons are short and sweet.

If you're introducing [unrestrained] kids into the situation it's too late, as the pilot you're responsible.
 
msinger and N017RW I always thought of you two as being able to understand the language better than you have just demonstrated.

Read it again and this time try to think of what I said, in a logical way.

ccase39, before you infer, outright state, that I am being irresponsible, you should have read this:
http://download.dji-innovations.com...Phantom_2_Vision_Plus_User_Manual_v1.8_en.pdf
It's the P2V+ manual and it clearly states there is a difference in time to stop the motors.

The risk of a tip over, as you mention when using CSC, is a result of doing it improperly.

Maybe it's just the way you wrote your reply when you quoted me, but it sure looks like you tried to state that I was wrong and irresponsible. I am neither.

Sorry to contribute to "Troll Talk" in your thread yorlik.

This thread is about the importance of using a wrench to tighten your propellers.
Shall we carry on with the topic now?
 
Use medium or light locktite, if you don't take the props off then great, if you do take the props off, after a few uses of loctite the threads become gummed up a bit acting like a nylon locknut. helps to stop the prop from backing off the little bit that starts a prop falling off.

Not trying to be a troll but many sites, as well as the manual state that these things are not toys and are not meant for children.
I would suggest to people not to land (intentionally) close enough to a child that they have a chance to run up to it and shove their body parts into the blades. As far as CSC shutdown, yes doing it properly does work, but landing by keeping the throttle down takes the use of another hand out of the equation which to me lessens the chance of a tip over. I never got very good at the CSC shut down and one tip over is enough for me
