Greeting from Malaysia. I am new to drone and have just bought a P2V+ about 2 weeks ago (still in the learning stage) . I need some advice here and would highly appreciate if you can help me out my question below......

I learnt that the gimbal clamp MUST be removed before the drone can be turned on. But yesterday, I have just forgotton to remove the gimbal clamp and turned on the drone with motor activated (without props) just to discharge my unused LIPO battery. The sooner I realized my carelessness 15 mins later, I immediately powered off the drone and subsequently removed the gimbal clamp and powered up the drone again. I observed no abnormality of the gimbal and camera as it can still function well (touch wood), except that I could feel some heat on the steel part of the camera.

May I know if my gimbal or camera will slowly damage later? Will its performance be affected? Is there a threshold for how long the gimbal can hold without removing the clamp when the drone is on?

Thank you in advance for your guidance!!

You could possibly overheat it and may cause damage to the board and electronics.  You might be able to get away with forgetting a few times, but repeated mistakes like that will eventually cause the major damage to alignment to the gyros and heat damage to the circuit boards.

Hi Gerry, thanks for your tips. I will be more alert next time. Hopefully it didn't cause any damage so far.

The software recognizes this when the protective bracket is forgotten and this indicates.
In the next revision, the firmware should be extended, then the Disable the engines to prevent damage.
Can you improve this proposal forward to the developers.

The gimbal clamp should have been made out of red plastic instead of clear which is hard to see. I ran a ribbon through mine for now but plan to get a red Remove Before Flight ribbon. Just looks sharper.

Hi all.

I have a newly purchased DJI Phantom Vision 2+ v3.0 with the latest firmware.

The second time I turned it on, I forgot to remove the gimbal clamp and left it on for approximately 5-6 minutes before the Phantom itself started producing a noise that sounded like a high frequency audible alarm.


I have 5 questions and I am wondering if anyone can help in answering them

1) I am wondering if the bird itself has such an audible alarm feature on it to remind users that they should remove the gimbal guard or whether this sound was the gimbal servos being tortured?

2) This happened just once and the gimbal seems to be working OK since but I am wondering whether such an incident has damaged the gimbal.

3) Are you aware of any safety features on the gimbal mechanism or the bird's control unit to detect that something is impeding the gimbal's motion and prevent further attempts to move it in order to save it from being damaged?

4) If I turn the bird on and lift it up by hand, the gimbal tries to remain stable and does so well. If however I turn the bird sideways or up or down to the point where the gimbal can no longer remain on the horizon, it seems to turn itself off. Is that normal? It comes back on soon as I re-establish an angle that it can cope with.

5) When I turn the bird on, the gimbal stabilises itself and within a second or two after it does that, it flicks once (by flick I mean, a sudden tiny shake or small movement). It does that always once, right after the first stabilisation when turned on. Is this normal? Do your gimbals do that too?

Sorry for the many questions but I haven't been able to find answers to these exact points and it would be nice to get that information from someone.

Best of luck with your flights!

p.s. "Remove before flight" ribbon is in the post ;-)

Reporting back.....

The props came out *great"! Pretty much a match with the 'snap on' prop guards I'm using.

The gimbal protector OTOH wasn't having any of it. Nothing. May as well have been made of steel!

Oh well, I tried. Key chains will be here Friday.

Maybe just get a brighter gimbal lock. This one fits well, is easier to clamp on, and is impossible to miss if you leave it on:

adrianjacobs, all versions of the P2V+ do that. The problem is that can damage the gimbal if it happens often and/or for an extended period of time (per the discussion above).

The gimbal was most likely not designed to stabilize itself in positions that the Phantom is not able to fly. And, considering that you won't be flying at that angles, I don't think it's something to be concerned about.

Yes, they do that, that is the automatic calibration of the gimbal extremes of movement programmed into the flight controller.

I have forgotten to remove the gimbal clamp at times when I download the images to the computer.  I think the remove before flight tags will help with that too.

I'd like to ask if anyone has actually damaged their gimbal by leaving the clamp on. I've seen a lot of talk about it burning out and a lot of warnings but I have never heard/read a first hand experience where a gimbal was actually damaged.
I ask about first hand experience because to me it seems more like an urban myth that actual fact. For a brushed motor I can see this being a potential problem... locked shaft, high current on the brushes and damage is possible but in the case of brushless motors it is unlikely. Oh, and actually it makes no difference if the gimbal is locked or not, it still uses about the same amount of current and has about the same cooling. With the clamp removed the gimbal holds the camera in one position so it's not like it's completely off.
I believe that the warning to remove the gimbal lock and the screen pop up is just to make sure you get good quality video. Otherwise the gimbal simply doesn't work, there is no stabilization and the video will be of very low quality.
BTW, I have left the gimbal lock on and even made a few flights with it. There is no excess heating, so damage whatsoever but the video feed was very shaky. Recording is not possible with the gimbal lock on because the app will not let you press the record button.
What do you guys think?

Wow! Thanks to everyone for your replies. Good to hear some reassuring stories. Still, can't believe they built the clamp out of low-key transparent plastic! :-)

My drone arrived today. I've already removed the gimbal clamp but I still getting the message "Aircraft Motor Overloaded. Check that the whether gimbal clamp removed". I suppose it's broken.
Any advice?
