In case you haven't noticed there's been a lot of chatter lately discussing the DJI Woo Kong products. Since I haven't had a new multi-rotor project in the works for some time I decided to give the F.450 Flame Wheel ARF quad kit a try and couple it with the WK-M autopilot system.

So just how strong are these frames? With composite support arms they have to be prone to be easily damaged right? Those were my questions before watching the following video. You can form your own opinion after watching the torture test.

Here is a short very well done build video done by Gary Travis.

The thing that I noticed first was the fit and finish of the F-450 Flame Wheel. Things go together so easily that the whole project can be done in a couple of hours with minimal soldering. Forget all those little capacitors and SMDs you won't have to deal with them at all with this little baby.

The F-450 didn't come with any assembly or set-up instructions in the box but it didn't take me long to find it at the DJI web site. Once downloaded and printed the information really helped. This is a link to the DJI download page here you can find all the specifics of the product line, product notes, 32 & 64 bit drivers, assistant software, manual, and the ground-station manual, that's what I call one-stop shopping.

Drivers & Manual

I run Windows XP on my desktop so in that case I needed the 32 bit driver installed. I use Windows 7 on my laptop and in that case I needed the 64 bit drivers installed. The manual itself covers everything from assembly to installing and setup using the Woo Kong assistant software.

What DJI says about the system:

DJI Wookong Multi-Rotor stabilization controller is a complete flight system for all multi-rotor platforms for commercial and industrial AP applications.  Unlike others, WooKong allows the use of regular ESC commonly used in RC helicopter without any wiring modification; Heli mode setup providing a seamless transition for current Ace One AP professionals.  WK-M utilizes high quality components precisely calibrated with temperature compensation in all gyros and sensors, industry renounce flight algorithm in autopilot and UAV.  IMU damping system is rated for gas engine best in the class.

Attitude mode maintains precise altitude hold for indoor flight while GPS mode provides superb position hold outdoor.  External LED flight mode indicator light can easily be observed by pilots under any condition.

WK-M can be flown in one single full auto (GPS-Atti) mode from take-off to landing; or in Atti mode while manual mode has stabilization activated.  The system is easy to install with user friendly software allowing on-line firmware and software upgrade.

The new WK-M kits are supplied with 920KV motors that are capable of using either 3S or 4S Lipos. The GPS is now also equipped with a compass unlike earlier versions that did not require calibration.

Following order of kit assembly

Solder all speed controls to the lower plate which also serves as the PDB (power distribution board)
Solder the PM (power module) and the battery leads with plug to the PDB
Mount all motors to the support arms
Mount all support arms to the PDB
Mount all ESCs (speed controllers) to bottom of each support arm using servo tape, Velcro, cable ties or a combination of all.
Mount WK-M components per instructions in user manual, PMU (power management Unit, MC (main controller), IMU (Internal Measurement Unit, LED Indicator, GPS & Compass.
Test system setup with assistant software per user manual.
Install top plate
Mount GPS
Install props

I wanted to protect the GPS as well as the other electronics and used some Velcro to mount the GPS on the inside of a ZigCap which seems to work out rather well so far.

My only real hurdle with the entire build was setting up the 3 flight modes including failsafe. After using MKTool it was hard to break away and start thinking a bit differently. Tahoe Ed was kind enough to provide the information that I needed to get the calibration performed so I could actually go out and fly. Thanks Ed!

The following info was provided by Tahoe Ed, I hope it helps you too:

I can only comment on how my JR 9503 radio is set up with an AR8000 Rx. To set up failsafe in the Rx, I did the following. If you have a switch set up to trigger failsafe then you can turn that switch on, if not move the travel of the mode switch so you get failsafe indicated in the Assistant. Now set the travel for low throttle to 0% vs 100%. This should move the throttle indicator in the Assistant to mid throttle. Once you have that done, shut down the WKM and the transmitter. Insert a bind plug in your receiver, again mine is an AR8000, and power up so that the receiver is in bind mode. Remove the bind plug, the receiver should continue to flash. Now turn on the transmitter with the bind button pressed and wait for the receiver to bind with the transmitter. You have now bound with the settings in the transmitter bound to the receiver if you loose signal. Again, power everything down. Restart your transmitter and reset the travel on your throttle and make sure that you are no longer in failsafe. Power the WKM back up and connect it to the Assistant. Now when you turn your transmitter off, the throttle should go to mid point and the mode should go to failsafe. I hope this helps you. I had to go through this several times to get it right.

I want to mention here that the DJI WK-M Autopilot system is virtually plug-n-play. There is no soldering as there is with a MK. If you're the type that has steered away from MK because you were uncomfortable working with those small PCBs and even smaller SMDs then this system is for you.

The Flame Wheel flew with the default settings and it flew really well, I was very impressed overall. I went through the first 3 packs like me and the Flame Wheel had been old friends for years. This is the type of system that you'll put together and have fun flying it instead of spending lots of time messing with fine tuning. I like charging a pack and going flying without all the other headaches.

I also like the fact that if you do crash the DJI it isn't going to set you back big bucks to get it to fly again. Yeah I like that.  ;)

Pics are great BUT, lets see some video!! 

Any thoughts on payload capacity?

Setup for the WK-M is slightly different than the NAZA but this will give you the idea how the assistant software works.

DJI Naza Assistant Software


SPECIFICATIONS OF F450
Model     Flame Wheel 450 (F450)
Frame Weight     282g
Diagonal Wheelbase     450mm
Takeoff Weight     800g ~ 1600g
Recommended Propeller     10 × 4.5in ; 8 × 4.5in
Recommended Battery     3S~4S  LiPo
Recommended Motor     22 × 15mm or 22 × 12mm
Recommended ESC     30A OPTO

Rob sorry man but I really suck at taking video. All one needs to do is go to YouTube to see the F-450 Flame Wheel in action some with cameras

This is a signal lost failsafe return to home and auto land sequence. The guys may have missed the mark by a foot but it's still impressive.

I'm here to say even my wife can build one.  :-X (as long as she gets her own tools)   :D

All kidding aside the F450 & WKM is really a good deal. It flies like a much more expensive multi-rotor and it's cheap to fix.

Buzzed, very nice build thread.  I am glad that I was able to help in your efforts.  I do like the WKM in the ease of set up and the lack of needing a soldering station to build one (still have mine from my MK build but it is now redundant).  It appears expensive on the surface but not having to use $75 escs is a plus.  That noted, not all escs work.  The WKM likes 400 refresh rates.  The faster the better.  I just got through reflashing some Turnigy 18A escs to smonks hex files.  I have not had a chance to fly with them yet.  Right now I am using the DJI OPTO esc's exclusively.  They work and unless you need more that 30A the price is right. 

I understand that DJI has reinforced the hubs of their props for the 10" at least.  This should take care of any concerns about prop breakage in flight.  I have to note that I have never had a DJI prop, 8" or 10" break on me in flight, but many have.  Right now I am using Graupners in both 8 and 10's.  I think that Ziggy sells both of them.  I got a drill press from Harbor Freight and a metric step drill to drill out the 8's.  The good news is that the bottoms of the 8's are at 8mm.  You only have to drill out the top and you have a perfect mount for the DJI motors.

Good flying my friend!  Cheers.  Ed
