Maiden flight of my Blackbox flight data recorder on my Blackout 330 (8 min 30 sec)


This is the Blackbox flight data recorder for the Naze32 I'm currently developing in order to investigate uncommanded yaw control problems with my quad at high speeds. However, since I was limited to LOS flying today (which limits my top speed), this was a problem-free flight! The current time in the video is in the centre, marked by the vertical red band.

The Blackbox is a patch for Baseflight which causes it to send RC commands, gyros, PID intermediate calculations and motor commands to an onboard OpenLog serial logger connected to the Naze32's main serial port at 115200 baud. This data is captured on every single FC loop (here at 415Hz), so basically everything about the FC's behaviour is losslessly captured, and any quirks with the craft can be identified and solved!

The recorded datarate is about 8.25KB/s, which allows for essentially unlimited recordings on an 8GB microSD card (that's 30MB/hour).

The Blackbox software isn't complete yet, but I hope to make it available for testing soon.

It looks like YouTube hasn't been kind to the colours I chose for the graph, here's a still screenshot:



The couple of gaps in this log are due to the FC sending data a little bit faster than the OpenLog could keep up with. I'm working on improving that: I've reduced my data rate by 15% by improving the compression applied to it, and I'll investigate using a faster microSD card (currently I'm using a 8GB no-name Class 4 card).

The OpenLog is tiny, at 15x19mm. I wrapped it with electrical tape and attached it to the frame with the microSD card slot pointing outward using double-sided foam mounting tape:

This will go over building the Emax 250 Pro Nighthawk with the Massive Acro\32 board. It's applicable to the carbon glass V1 as well as the all carbon V2 versions. You can also use some of the pointers in this build log on other frames\builds.

As with any carbon frame you want to wash it thoroughly as carbon dust is very unpleasant and hazardous. You can go one step further and wet sand the edges so they aren't sharp.

Carbon fiber is conductive so you need to make sure no exposed connections can short against the frame. In addition, carbon fiber will block RF signals so place your FPV and radio receivers so that they clear the chassis.

Finally..........soldering should be the last thing you do if you're new to DIY. Mock up, measure, re-mock up, experiment with different configurations. Throughout this pictorial you may see the FCB mounted with pins installed but unsoldered......this is for illustration purposes. The first group of pictures will go over installation of chassis\PDB\FCB for location without anything soldered, and the 2nd group of pictures will go over soldering the parts. The pictorial may seem out of chronological order at times. When soldering, you want to solder connections to the PDB without it mounted to the nylon standoffs to avoid melting them.

Onto the pictorial

First thing is to install the bolts through the main plate and screw on the spacers. You want to leave them loose for now so that when you bolt on the bottom plate, the...Continue Reading

I've been wanting to try this for a while, the work I did on my Dyna-soar/Titan II got me motiviated. I do a lot of depron RC airplane construction, my thought was to do a model that typically needs lots of nose weight or is very heavy, and see if using stringers/centering rings and 1mm depron skin I could make a large light model to fly on E-15's......

The only wood in this model are two centering rings in the upper portion that are lite ply, and the balsa coupler I used for my BT-70 upper tube since it was handy at the hobby shop, the rest is depron sheet, cardboard motor tubes and some .04 styrene sheet.

For drawing centering rings I've been simply using a strip of cardboard, put a thumbtack in one end, and measure to the needed radius, poke a hole and insert my fine sharpe and draw it directly on whatever I need to cut, no need for a compass. This can be used for drawing cones or transition shrouds as well where you need a very long radius.

I cut a 7" by 2" triangle out of 6mm depron, grooved and glued in a 1/8" carbon rod which will take the brunt of the nose cone landing force....I then added perpendicular triangles, and took turns gluing in triangle filler pieces and carving those to match the original triangle pieces a quarter at a time...eventually I had nose cone shape. I left one quadrant unfinished so I could add weight if needed, then finish it. I added a few gradually increasing centering rings to get the needed outer diameter.

I cut...Continue Reading

I was asked how to duplicate this DX6i mix for the 3-channel HobbyZone Champ (which duplicates "steering" onto the left stick, Mode 2) on the DX9, but with UP elevator also mixed to aileron






Note: The following assumes none of the Champ's channels are reversed out of the box. Just going from memory, I don't think any are. I did this DX9 setup just using the radio's servo monitor screens, I didn't actually have my Champ bound to it.


Go into MIXING on your model's Function List. We want RUD to be the master because we want the aileron channel (which is what the 3-channel Champ's rudder is actually plugged into) to follow the radio's left stick rudder commands or RUD channel (assuming a mode 2 radio).

There is a default mix already there called RUD > AIL/ELE... go into it.

Description:



In the RUD > AIL: mix, set both values (two because you can set left & right separately, we want both) to 100%. Set Switch to ON if you want this mix to always be on. Or you can set this mix to one of your switches, but I can't think of a reason why you would want to.

I suggest not doing your UP elevator mix here (if you want one) using it on the rudder because you'll probably want that mix on your aileron channel instead which is what you'll still be using for steering in flight, This RUD > AIL mix is mostly for practicing, getting used to or maintaining the habit of steering with left stick rudder while still on the ground with 4-channel planes (you...Continue Reading

So, since MultiRotorMania.com was so efficient in getting my order out, I actually had it waiting for me in my mailbox yesterday; now it's time to do something with all that multirotor goodness!

The RCX arm are really only drilled for the 2204-2208 size motors that use a 3mm screw (the 2mm slots are 45° off and leave the motor wires hanging off the side rather than going straight down the arm), so I had to find washers to be able to use the 3mm slots.



This is the CORRECT way to "washer out" 2mm screws going through 3mm slots; ordinary 2mm washers are usually not near wide enough and they will usually deform around the shape of the slot when you tighten them down. The cup shape on these makes them much more rigid and resitant to this deformation. The original m2 x 6mm screws that come with your DYS 1806es will work with these.

Fellow members who fly helis will recognize these; they're 2mm frame washers for TRex 450. I have oodles left over from crashed frames; if you don't have any, you can get a "TREX 450 Frame Spacer & Washer Kit" that has 30-50 of these and another dozen or assorted aluminum spacers for $6-ish from eBay.

Don't forget to LockTite the screws!



I'm doing another "sandwiched ESC" build but this time I need more space than my 4mm AL spacers will give; the stiffening caps are 8mm diameter. I'm using these Hillman # 880427 because they're cheap and readily available from any local Homeowner Hell for about 0.40 a package....Continue Reading

...and had myself a little adventure over the weekend. *Flashie-backie noises*

Saturday I took the kiddles with me back to San Antonio to visit friends and do some shopping; found some excellent deals and gave the boy a Lego Brain Blast by giving him money to spend at the Lego Store. All he had to do was be "Better than Green face" good all day; and he was! Even got through dinner with my old flying club buddy Rick without spoiling it.

So, after the Lego Store closes we head back home; about halfway, in the middle of this long stretch of nowhere and not a house in sight for miles... ZIPPP! a flash of white feet and THUDDD! I hit something. At first I thought it was a dog but it turned out to be a housecat; for sure it was somebody's pet, because it was too big and too well fed and groomed. I turn the car around and my son asks "Why are we turning around daddy?"

"Because I just hit someone's pet with the car, and nothing deserves to die alone, son. It's the right thing to do."

"Well, Socks or Mittens, it looks like you picked the wrong night to chase cars..." I say, picking up the battered body from the pavement and laying it in the ditch by the roadside. In the yellow glow of my headlamps, I watch the light fade from the poor creature's eyes; only a few moments really, but it seemed like forever. I say a brief prayer for its soul, then turn my collar to the cold and damp and climb back into the car.

I drive into the...Continue Reading

In order to do a proper scale model with the unique features intact, the Fw-189 needs both scale landing gear and prop spinners. It was a lot harder than I expected, but I've modeled up scale spinners with no visible attachment screws, and a free, contra-rotating nose piece with curved vanes, just like the original. I've got some hardware on order and then I can try it out and see how it works.

It was going to happen. I knew it was inevitable. A while back I had my first run in with a park person...

I'm not going to go into alot of detail. I was flying a quad FPV while doing photography. Alone. No one around me. I was confronted, threatened with a citation, etc. I managed to talk my way out of it and left. After the fact I did make contact with the organization.

The level of ignorance about what I was doing was pretty high. They considered my activity as an act of vandalism. They did not want me there because they wanted to keep the park vandalism free. This is how they viewed me. When I mentioned that I was a photographer and had been photographing in this manner for over a year now I was told that those photographs were "just" evidence of my criminal activity. At this point I quit while I was ahead.

I have been mulling this over for almost a month now. The conclusion I came to was that I need to stop posting any media that can be construed in a negative manner. And that boys and girls is anything shot in park areas or any other spot where someone may take offense. Till the madness ends I'm just not posting.

The citation that they were trying to hit me with carried a 30 day jail time. A non supportive judge and a bad day could have made life very unpleasant for me.

The point that ended up working for me was when I pointed out that the Quad was autonomous and was flying itself. Therefore I was not flying a remote controlled aircraft in the park. Thin but technically correct. Not something I would want to argue in front of a judge and I don't think the park official wanted to either.

I will continue to fly and photograph. I will not post anymore though...

I have a Byron Corsair that I want to maiden this Spring or Summer, it was built without flaps. As I recall, installing flaps was an option in the Byron manual. Does anyone have experience flying a warbird in 1/5 scale without flaps? I should have no problems, but i figure any input would be good.

Ultramap finally compiled, after a week. The phone no longer showed a static menu button, so it required a layout change, which required recompiling the program. Adb no longer worked with the new phone & required an upgrade, but Eclipse wouldn't upgrade, so a new version of eclipse was required.

Eclipse wasn't catching all the errors in the version change & running it with constant missing class errors. The xmlns:android="http://schemas.android.com/apk/res/android" line wasn't compiling anymore but wasn't necessary. The phone version was API 19 but Eclipse was compiling 20. Eclipse needed to install API 19 from Window->Android SDK manager. The API number isn't the same as the 4.4 number & there's no easy way to find out what API correlates to the 4.4 number.

All the project.properties files needed to be hand tweeked to say android-19. The AndroidManifest.xml files then needed to say android:targetSdkVersion="19"

Installing Google maps API is a multi step process. You have to download an Eclipse project called Google play services in Window->Android SDK manager, import it as an existing project from the android-sdks/extras directory, & compile it as a library. It has to be linked into your app project, but there are multiple properties dialogs with multiple fields for libraries.

Adding the jar file to Package explorer->Ultramap->properties->project references doesn't work. The entire google play services...Continue Reading

I post items for sale from time to time. I also read the nightmare discussions of "he said, he said this". This has prompted me to do a little post of "terms of sale" when purchasing from me. You can't say you didn't know! A link to this will be posted in every ad.

If I say it's used it is. If I don't remember if it is then I'll play it cautious and call it used.
If I say it's new it is. Everything I sell has pictures of the actual item and occasionally a stock photo will be used IN ADDITION to the actual item for sale.
All items, unless expressly stated in the ad, were working when it left my hands. I test every item so I can say it works when I sell it.
I am completely open to hear your complaints, concerns or requests and will always make an attempt to work out issues with you. If however you are a crack pot or otherwise any type of undesirable person all bets are off.
I sell to who I want to sell to. Usually this works on a first come, first serve basis but there are those.........

Shipping:

I DO NOT ship outside of the U.S. of A. The only exception, at my discretion, would be to Canada if you've been a member long enough with trade feedback I'm agreeable to.
I use USPS and UPS. If you favor one over another inform me and I'll use that carrier.
I pack to protect. And usually this means a bulkier package costing more to ship. You will be happy, I insist!
Insurance is your responsibility to request and pay for above and beyond all other terms/expense.

This airspace open for updates/revisions!

Here's to an amicable transaction, happy flights.

I was able to get out and fly my new E-Flite P-51 Mustang today after not being able to fly since the maiden. In many ways it felt like the maiden all over again as you can see by how poorly done my take-off was. It was still a great flight and I still have the grin on my face
