I was sent a Naza H to Test by a supplier in the UK, i have a Wookong H and an ACE One.

The Naza H will not do nitro, Gas or Turbine Which is the main reason why i didnt test, after a few mails back and forward this was the conclusion of the factory at the time. I suspect but not 100% positive that the damping will not cope with the vibrations or frequency of the engines, turbine.... The accels Gyros are in the same case as the rest of the electronics.

The Wookong H has a sperate unit for the accels & gyros, which copes with my Spectra G FBL 231PUH. Fair amount of vibration even though i have balanced everything.

It will not not do way point, only GPS Hold, I have had a friend at a field who has never flown a heli before do a perfect figure of eight with my spectra in GPS mode. This was just a test at the time i dont not consider this a good idea, always learn to fly to a good standard before fitting one, if the IMU fails it will revert to a flybarless controller!!

The ace one Will do GPS Hold, Single way Point (point and Click), Multiple waypoints, auto land, Joystick Control etc

From this u can draw your own conclusions of why one costs more than the other.

I do not work for DJI, A friend of mine has a company that deals in DJI systems in the UK, so i get to test stuff.

hello, I just installed a Wookong am on my logo 600.

I have two questions:

1) When I have a good flight speed in "ATTI/GPS" mode, it is virtually impossible to lose altitude even strongly lowering the handle of the swashplate ... the only way is to go is when the helicopter is hovering. Is this normal? Is there an adjustment to do?

2) If I put in "ATTI" mode, I get to take off, but it goes no more than 2-3 meter, but impossible to elevate the helicopter with the handle of Swashplate ...

sorry for my bad english

Alain

Alain - No that is not right, you should be able to alter the height of the helicopter in atti or GPS when flying or hovering, by moving the Collective.

Can you post your settings?

Thanks Malcolm,

here is my current settings.

The settings of flybarless are OK in manual mode it works well
just like I use a vstabi

I tried to increase the vertical gain, but that does not change the problem of up / down when the helicopter advance has good speed,
i can not seem to get a few meters down with the stick of
collective almost to the bottom

Thank you for your help

There is nothing wrong with the settings you have there.
How have you set the collective +10 : -6 ?

When the helicopter is on the bench in GPS mode and the collective is moved can you see the swash plate raise and lower slowly?

Hello Malcolm,

I found that the curve was not very good, now have changed and it is easier to get altitude down.

question: the curve must set it to go from -100% to +100%
like drone with wookong M ?
or set it as a normal helicopter without wookong h ?

I still have that "ATTI" mode, it is totally impossible to climb over 2 meters! I can not find the error, someone has an idea?

if I want to get a better reaction from my helicopter (more nervous), which setting should I change?

Is it possible to make a loop? in "attitudes / gps"?

thank you very much for your help!

Alain

This from the manual

"B5 Pitch and Throttle Curve Setup
We suggest you to use the following pitch curve for better lifting power and safety descending speed.
+10 -5.5 "

You have to get a pitch gauge and set your collective pitch curve so that at 100% you get 10 degrees of collective pitch and at 0% you get -5.5

Alain do you know how to set the blade pitch with a pitch gauge?

We have -7 to + 13

these values are measured in "manual" mode
in GPS or ATTI was no idea what those values
as the helicopter did not take off ...

should we do something in "ATTI" mode so that the elicopter
mine would climb higher than 2 meters?

special procedure for take off?

in GPS mode, we have no problems...

or a fault in the Wookong?

thanks

Alain

Those -7 to +13 should work, they are a little high.

The semi auto take off and land i have never got working and read somewhere that it dosent.

OK this is what i normally do to when i fly it.

Helicopter in manual mode. Let the blades spool up, take off and hover the heli at about 5meters, Flick in to GPS mode, let the heli come to a stop and then just using the collective, Rudder, and elevator like a 3 channel toy fly it to a point where i want to loiter then let go of all controls.

The only thing i can think of is that maybe the sensor is getting hit by the downdraft from the blades, the altimeter is a pressure sensor).

Can you take a picture of your Installation?

Hi Alain,
I have read this thread with interest. Try doing the TX stick calibration. It may help solve your problem.

Ahmet

The price is higher because they know one of two things either you will pay or by something else. They could care less.

Hy, Ahmet, the TX stick was fully calibrated

Hy Malcolm, in semi automatic takeoff, you see a difference
behavior between the mode "ATTI" and "GPS" when up to a height of 5 meter?
I put the photo tomorrow

thanks

Alain- if you have followed the manual there should be no change in the helicopter attitude.

Here are a few pointers that might help.

Firstly make sure you do the compass calibration, this is important!

once you have done all the setup including the one above, you have to do a manual mode test flight, this is so that when you flip between flight modes, manual - atti - gps the software knows the central trim position, best to do it on a calm day.

Follow the instructions above, fly the heli and trim it so that when all sticks are centered its stays virtually in once place, if it wanders a bit don't worry, but try and get it the best you can.
Once you have done this, land the heli, dont move the trims!!

Fire up the software and follow the fail safe procedure. This will teach the WKH your trim points. Otherwise the system will think your giving an input when you are not, because the trims will be off center.

Ok once you have followed the fail safe instructions and saved your center stick positions to the WKH then proceed to the GPS test Flight instructions.

Forget the Semi Auto Takeoff!
Turn on you heli and wait until you get all the Sats. Spool up the heli take off and hover at a height of 5 meters.
Switch to GPS mode and the heli should stay in one place without moving any sticks, if it is moving slowly then your trims have changed and you need to go back to fail safe and teach the system the new trim offsets.
So if your heli is now holding station, move the collective stick up and it should start to rise, bring it to center and it will stop. Push the cyclic forwards about half way get to a speed of (10-15mph) and adjust the height of the heli, by moving the collective.

Hope this helps.

Thanks Malcolm,

in GPS mode, everything works fine, including the take-off semi-automatically.
My problem is that it is not possible to raise the helicopter
in mode "ATTI" (without GPS) is more than 2 meters,
I do not dare take off in manual mode and switch to "ATTI" if
this mode is broken!

can you try to take off in ATTI (without GPS) mode?
and tell me if it works?

Alain

ATTI mode
ATTI mode is the same as GPS mode except that it will not hold still. I don't understand why it raises up in GPS but not in ATTI mode. Your install looks fine.
The only thing I can think of is that your mode switch might not be set up correctly so it's not engaging ATTI mode, go into the software and move your mode switch and make sure that it engages the 3 different modes.

If that all is working then I think you will need to go back to your DJI dealer and get them to Email DJI.

I can't test it at the moment as my Spectra G has the ACE ONE on it, the WKH is in its box.

One last thing to check, when you switch to ATTI mode, which colour does the LED flash.

The LED lights up in purple. I wrote DJI support, but no response.

I just saw that there are other flybarless module can recover the helicopter in case of error and return a flat!

I think I made ​​a mistake in buying this Wookong H which is very expensive!

If its flashing purple then you are in ATTI GPS, yellow is for ATTI mode only and blue means its in fail safe,
Recheck the mode switch and make sure it is flashing the correct colour. Check in the software.
The WKH is a good piece of equipment, but it is not a bail out system. It is meant for scale and camera type helicopters, if you are after a bail out system for learning 3D then buy a helicommand, skookum, APS or co-pilot.

After a boom strike, gps/compass from wookong-H was damaged.
I know this wookong is discontinued.
It happens to be difficult to get a replacement.

Gps/compass from wookong-M would be compatible?
Gps/compass from naza?

Saludos cordiales,
