********** Note *************
I have not had time to triple check but it looks to me like someone screwed up and got the order of a least the Power Module and I2C pins backwards. This is not terminal but a big pain. So instead of the standard cable for all Pixhawk and APM power modules a custom cable will have to be made!

I have included the pinout lists for the 3DR Pixhawk attached below for reference so you can compare.

Scoopdreams noticed that the 6 pin cables provided are not straight through but reversed. So using one of those cables, and swapping the two center wires, to get the voltage and current sense correct, does allow connection to a standard power module but don't use the normal cable provided with the power module.

Top image is the standard APM and Pixhawk power module from the perspective of the photo, the same in both pictures, grounds are on the left and 5v on the right. Note in the bottom picture the Pixhawk lite is the opposite.



********************************


Having built a variety of multirotors based on Arducopter I have to say I like the small mini versions because they make it easier to fit everything in limted spaces. With the end of life of APM many people have been waiting for a mini Pixhawk.

After three tosses, adjustments to the elevator and the CG the RC Gull flew well. Pretty fast and rather convincing.

It is true what they say about the Jart M70s flaps. Just about stops in mid air and hovers to a soft landing. Thanks to the excellent build by Mo it needed no adjustments. Flew out of my hands and performed like a champ.

The Typhoon flew great as usual. First time I have flown it with full ballast. It's a different plane with ballast. Faster and tracks better.

I decided to finally take out the DCH-2 Beaver this evening. Lake was calm...Winds were about 5 mph slow gusts to calm conditions. lake was like glass....First had a problem with the steering on the floats that was easily fixed and she was back out quickly. So I take off and the plane gets up fairly easily with a small bit of elevator she was up and in the air looking awesome! So I take a long wide scale left turn around the bay of Lake Palestine and as I am about 150 feet in the air she just stopped responding and began to spin uncontrollably. I was hoping I could save it from the dive but it didnt recover.....so in the skiff we went. Me and my son drug out the boat and looked around for paddles and none were around and the sun was fading and fast. We find some shovels and decided that was our only option. We could see the landing lights on the craft and headed towards it. My son lost the paddle (shovel) about 200 yards into the trek....and we had about 500 yards to go. I am really at this point debating my decision to make this trek to begin with. With the sun fading fast I was really getting tired fast and then my son says to me that there is a hole in the boat and we are taking on water. I think to myself that I just lost a plane and possibly might lose the race so I begin to paddle faster. It seemed like forever and a day but it had only been 30 mins of paddling and we were still about a 100yards away...with water filling the bottom of the boat just enough to get my...Continue Reading

So I bought the Emax 250 quite some time ago. After a substantial time procrastinating I finally started working on it. The plan was to cut and solder the motor wires to the ESC with no connectors so lighten the load. After several attempts I failed and managed to fry 2 ESCs and a motor that is stuck in a jitter mode. Not a huge deal but now I was faced with either stick with the stock motors and ESCs or going big.

So I decided to go with some Cobra 2208/20 2000kv motors running some 6x4.5 props on a 2200 4s. Going to have to order them when I get some of the money back from some of the items I have invested in.

And I finished the plane for my wife. Its a great plane and I have it finished except for the fact I didnt read the entire page for the HK tx. Seems one of the channels is reversed and I cant do it without the correct cord that I ordered shortly ago. Hopefully everything I ordered will be here within the next 3 weeks.

Fired up a segment of the last sonar circuit, built 3 years ago. Stepped up the voltage to 41V with a 43k 100k parallel resistor network & after a period of fits & starts at 500mA, it ran off 2.5V 100mA just fine. It drove a pulse every 50ms. The voltage hitting the transducer would have been slightly less than 41V.

The next steps are building up a new receiver & recording the waveform on an actual drive. Skepticism keeps progress slow.

This is the second batch of flights with a special guest that showed up after John and I started getting the hang of it. We went out and did some more today and I even tried some launches that matched its name with pretty good success!

Of course those aren't shown in this video but will be showing up soon!

In Lockey's Dollar Tree Foam ... EZ-Jets thread he posted plans for a Mirage. I asked him if he ever considered making a Kfir, he pointed out that a Kfir is a lot like the Mirage. I asked Lockey for his permission and he not only granted permission he even helped me out by sharing his SketchUp file. I thought I might take a stab at converting his Mirage plans in SketchUp to make a “sort of scale” Kfir C2. In other words the silhouette will match up to the 3 view drawing.

I want to build a Kfir because; I fell in love with the lines of the Kfir when I first saw them at NAS Oceana back in 1986 or 87 when I was in the Navy. The U.S. Navy/Marine aggressor variant is known as the F-21. Plus, Lockey’s jets and videos make them seem not only possible but fun. Bouncing some foam into the ground will definitely be cheaper than my fiberglass Laser that tested the soil density at the airfield one summer afternoon.

This is my most ambitious attempt in foam building and first scale type build in either foam or balsa. As I was typing this out I realized that with a 30" wingspan it will be almost 52" long, hmm…will that even fit in my 4 door Passat?!?!) I am enjoying the process of "bashing" Lockey's Mirage design. Come to think of it, the only balsa kits that I ever built without bashing the kit or plans was my Midwest Lil Tri-Squire, Q.B. 15H, Q.B. 20H, and an Ace Littlest Stick.

Here is my main 3 view drawing and some screen shots of the SketchUp progress so far.

I've got a little wireless homeowner weather station. My wife gave it to me for my birthday; she knew I'd been wanting one. And this was before I even started flying. I enjoy it a lot.

Now that I'm flying I enjoy it even more. It gives me barometer, temps, humidity, some other stuff... and WIND! Current, average, peak. Useful information for a flyer.

Today the wind was howling most of the day. We've been in the midst of severe storms all weekend. A tornado wiped out a rural home about 8 or 9 miles from here last night. Rained over an inch last night. Most of today the average wind speed was 24 - 25 mph, peak at or over 30. It was a rare moment of peace when current wind dropped to 17 or 18.

Then just before sunset, Poof! 2 mph wind, 3 mph average. So I grabs the Sport Cub and out the door I go.

The poor little Sport Cub is undoubtedly going to be happy when I get flying without SAFE under some sort of control. Right now there is a lot of crash, boom, bang, thud. I've only got about a half a sense of orientation flying in Beginner mode, and it goes right out the window when I flip that switch. I don't have enough brain power to keep track of orientation, and keep the plane in the air, at the same time. And when I get disoriented, well, there's a pretty fair assortment of buildings and farm machinery to run into even if the plane is staying out of the dirt.

But. But. The intervals between the crashes are getting longer and longer. I'm getting less likely to flip back to SAFE because I think, I can get out of this mess, I just... aw,

The only real problem with tonight was that the modest breeze was coming straight out of the eye of the setting sun. Launch into blindness. But then the wind backed around to the south and I could even see what I was doing.

Altogether an enjoyable evening.

Yesterdays Adventure (0 min 34 sec)


Was flying a Vector FC on a Naza F450 frame with an e300 pwr system. I fat fingered the controls, panicked just a tad, but recovered during the sudden unexpected downward fall. Didn't see the tree, until afterward, while viewing the recording. Lucky Man I am.

This is an example of DJI iOSD mini strip down to reduce weight and reduce clutter in your Phantom 2 or other DJI builds.

On many of our Phantom's we are using for stills work we are using a SonyRX100 which although is light, is quite heavy for the Ph2. So our aim is to strip down any unnecessary weight as much as possible.

We also mount the iOSD mini's internally together with cam plug connector. This means we don't need the casing and original cabling and plug and sockets.

Here are some photos of the DJI iOSD mini striped down and rewired up.

This reduce it weight by around 12gr

Well this thing first off is a wheeling freak! The motor seems to be running well with just a few tweaks on the main needle it puts out a lite blue stream of smoke. I did manage to roll the truck on the 3rd tank . I'm glad I made the modification to the body so the cage would fit. I've rolled it several times and it's protected the head and body as well. The truck doesn't do very well in med to tall grass . Maybe a better tire would help. I'm going to make some wheelie bars. And the rear hubs seem weak and sloppy I will look for after markets . The truck is top heavy so I will need to work on that. Here's some sweet pictures that my wife took of it while taking laps.

If anyone happens to run across my thread asking if a certain BL system would work in the ruckus, I closed the thread because after some research I realized it was a sorta dumb question.
Writing this because as a user of other forums, a closed thread looks kinda funny.
