Thank you. Pics are below. The following are included: 1. P3S complete (Drone + Modded Controller), with original box/manual/stickers (not shown in photos) 2. Propeller Guards 3. Official DJI backpack case 4. Neweer Neutral Density Filters 5. 1 Extra battery (Genuine DJI) 6. Leg Extensions (in...

In Excellent condition, flew few hours at most. Comes with extra battery, DJI case, lens filter set, screen shade (iPad mini), and prop guards. Never crashed, I no longer have time for it. Make reasonable offer. Manual/paperwork and original packaging available. Photos available upon request.

That was my educated opinion .. of course yours differs. We can also beat this to death and do an FEA calculation to see which combination of load/temperature/torquing affects durability of plastic. That’s an overkill of course, but a fun project if you have access to FEA software. In the end...

I did not imply they operate helicopters at resonance. Yes, I agree about not operating near a critical speed. My point is that, the physics of the problem make it such that the resonance frequency of the blade up-down depends on the RPM i.e., the resonance is NOT fixed. For typical turbine...

Plastic cracks like that occur because of 2 main reasons. 1. Screws are overtorqued, and 2 thermal stresses when operating drone in cold weather. Any temperature gradient near the screws and motor area (especially when u have cold shell and warm/hot motors) will more than likely generate...

In addition to unbalance, there is an even more serious condition that could lead to large vibration. The up-down (flapping) motion of a propeller blade has a resonance exactly at the rpm of the blade. That is why helicopters blades always operate near resonance, and the designs are tuned to...

Sorry have not come on this board for few days. Glad to see u’ve resolved the issue.

There are really many aspects to propeller noise and 'tones'. Not meaning to lecture anyone, just my 0.02. Fans/Propellers generate two types of sound: Tonal and broadband. The tonal component is due to the blade-passage-frequency and is calculated from: Freq = RPM * #blades / 60. Typically one...

I mis-spoke, I meant to write the PRO version. I've had such stuttering/glitching on lower speed cards, on the Phantom 3, Mavic Air and Samsung 360 ... all of those were resolved when I switched to the Extreme Pro. Really not sure what the issue with your setup is then ... sorry.

... for 4K recording, you’d need something similar to the Sandisk Extreme Plus. Correction: I mis-spoke, I meant to write Exreme PRO.

Possibly the speed rating of the micro SD card ...

Correct, if one has both quads (original and V2), all is needed is to run them quads with the props removed ... to assess the difference with the new sinusoidal controllers.

The only USB I see on the Osmo is the one on the camera. Given that it is 'gimbal-suspended', any cable you attach to the camera will undoubtedy hinder the operation of the gimbal and possibly get in the and put unnecessary strain ... unless I'm missing another USB port.

Given that the batteries do not last long, I have been looking for a car charger for my Osmo. The DJI website has a USB cable for charging the OSMO Mobile (plugs into the MIC input of the handle). The few questions I have are: 1. Would the USB cable also work on the Osmo (original, not Plus) ...

Not sure I follow. I have several 'generations' of iPads ... and have not noticed any improvement in brightness.
