I inverted the props
Inverted the NAZA
Had to switch the motor wiring on 1-2 / 3-4 as when it is up side down they are not correctly positioned

I have been having so much fun flying it this way that I still haven't taken it back apart to fix the LED and reverse it.

DJI is taking care of its distributors, that is what's most important.

The other pot is fixed.

A balanced prop and motor will create a gyro and actually stabilize the quad.
We will all have to wait and see what the new props look like or what has been done as the camera its self is mostly responsible for the Jello

That's what I said!

I had to do similar to make a U816 LB-sized quad fly upside down, although I had to invert the entire legs+motors and swap them as you can't invert the props. The main body stayed upright (same as you flipping the whole thing and then inverting the Naza)

I don't know how you know what they mean, but this is what they said about 4/5 flashes:

"They means the same. The only solution is IMU calibration. If that does not work, you need to contact your dealer for after sale service directly. We will unify it as 6 flashes in next firmware to avoid confusion."

I read that as they will make 4 or 5 show as 6 instead in next firmware.

And then they can avoid telling is what 4 or 5 flashes actually means.

You added this: (which also effectively swaps CW<>CCW as the motors spin the other way)

Moving the ESC wiring does not make the motors change rotation.
Otherwise you had it nailed.

What they did say was: they are going to 'unify' the different light signals in the next firmware, so there will only ever be only 6 flashes to 'make it less confusing'.


This is what I am referring to as fewer (codes) as I call them. Each color and flash is a different code that can be looked up.

Unify was not the best term to use.

In your list is missing: "Disconnect Compass or GPS"?.

What about send your "Inverted Phantom Easy Flight" video to DJI ? give Collin's team some additional to "innovate" around. (not send how to... )

At least if people search for it they will have access to the correct information. Not the CEO's false claim.

Also guys, regarding the gimbal. You are paying 1k for a GoPro3 ONLY gimbal. Keep that in mind. When the GP4 comes out (in about half a year) you will need a NEW gimbal. With the alexmos solution all you will need to do is change out the front plate (in Viacopter's BL gimbal).

The Alexmos gimbal is easier/faster to use/attach than the DJI gimbal. All you need is power, with the DJI you need to open the shell, connect the wires, etc. The only wire you need to connect with the Alexmos is the power lead that's in the legs.

However you want to paint it, it is Ranting and false information

These are your assumptions based on NO personal experience. You own neither gimbal and are touting how much better one is then the other.

Members here can think for themselves and make their own decisions.
Regarding needing a whole new Gimbal if the GoPro changes could not be more false.

The DJI Gimbal frame is a small part of the whole offering and can easily be changed and I will bet DJI will be the first to know if a different sized "GoPro X" will release. The GP3 is the same size, length and width as the previous GoPro's, only thinner so the piggy-back accessories still fit.

Compass is still connected and GPS is working but I flew in ATTI mode.
I did do a manual compass re-cal so I should have added that but don't know if it was needed.

Jello is caused by vibration and how that affects cameras with a rolling shutter, like the GoPro. A perfectly balanced, vibration-free, propeller will for sure create less jello in the camera. It's definitely worth the effort to balance your props and motors. But after just one crash, taking a nick out of a prop blade, it ain't gonna be perfectly balanced any more.

However, even a perfectly balanced prop is still going to create vibration. There's no such thing as a "jello-free prop".

Even if the props and motors could all be perfectly balanced, both in a static and dynamic sense, there is still going to be a pulse generated every time a prop blade passes over the Phantom body shell. The outboard blade is flying out in free space, whereas the inboard blade of the prop is flying in "ground-effect" as it passes in close proximity over the Phantom's arm. That source of vibration cannot be cured, unless you find some way to raise the props well clear of the Phantom body.

Moongel, sorbothane, isolation mounts of various stiffness, etc, can all be tuned very effectively to absorb vibrations of one particular frequency, and harmonics thereof, if you happen to know what that frequency will be. It's relatively easy to predict with a 2-bladed prop rotating at a known rpm. Two pulses per revolution, multiplied by rpm.

If you change the rpm, or number of blades, obviously the vibration frequency changes. The sorbothane that worked perfectly to isolate and cancel the vibration at the previous frequency, now might resonate at the new frequency and actually amplify the vibration.

Our quadcopters have four props, with two blades each, meaning 8 individual pulses of vibration for every combined rotation of the props. It would be really nice if those 8 pulses were spread evenly apart creating only small single pulses at high-frequency (8 small pulses per combined revolution x rpm).

But it's just as possible that four blades could simultaneously pass over the Phantom body shell, causing a pulse that's four times as big at a frequency of only 2 times per combined revolution.

Worse yet, our props are hardly ever going to be rotating synchronized in phase with each other, or hardly ever at the same rpm as each other. So good luck trying to solve that source of vibration.

After watching, reading, comprehending all that is involved, reducing jello during these sophisticated aerial video's I have developed a solution that completly resolves it. Available now for $99.99. Wait why not just give it away. Here it is! Simply eliminate all thrust,click the shudder and pan your camera in any and all angles and note the high quality clear images. Folks for me this now jello thread has become a real red harring. Enjoy your jello and turn the page. humbley,donnie

Why is DJI introducing a new phantom when you can't even get parts for the first one. My mount ( the white piece that screws to the phantom body) that holds the gopro frame is breaking and won't be able to use it much longer. Many others are grounded because they can't get parts. When is the ship coming in with our parts?
