The Alcázar of Segovia (Spain) Aerial

V016.

The unique silhouette and privileged location of theAlcázar of Segovia, a UNESCO World Heritage site along with the massive aquaduct and town of Segovia which both lie nearby, is several centuries old, though the location has been in use as a fort since the 12th century. Primarily Gothic with Renaissance alterations, it was originally a fortress (year 1122), but has also been a royal palace. The castle is surrounded by two rivers–Clamores and Eresma–flowing on either side. These rivers not only provide water for the greenery around the castle, but also add an extra layer of defense.

Most part of the shots are from the front view. For safety reasons I didn´t fly over the entrance of the Alcázar, where all the visitors are walking around.

Aerial footage shot at the Iglesia de la Vera Cruz in Segovia

V015.

It has been a while since I recorded my last video Aerial real state, so I couldn´t wait for recording a new one! It was an early morning shot on a fine sunny day.

Consecrated in 1208, Vera Cruz was built by the Knights Templar to house a fragment of the True Cross. It is thus not really a parish church or even a monastic church, but primarily a shrine. Vera Cruz has a unique 12-sided exterior with a tower on the south side. Its shape is patterned on the Church of the Holy Sepulchre in Jerusalem, where according to legend the True Cross was found by St. Helena in the 4th century.

Removing GoPro fish eye

Here you can see the difference between the original footage (1080, 60fps, M FOV) and the results removing the fish eye with the lens distortion effect (value:  -15) in Premiere. In my opinion recording in medium (or wide) FOV helps preventing the jello effect and makes the footage look nicer.

V014. Recording date: 21-07-2014

Some scenes have been filmed with FPV. The GoPro Hero 3 with medium FOV, in my opinion, makes the video look better and probably helps avoiding jello and vibrations in comparison to recording in narrow FOV. I used the ND filter (3 stops) too.

Flying the Iron Man 650 with Tarot T-2D gimbal

V013. Recording date: 21-07-2014

After recording the Countryside aerial video I had to wait for a landing leg spare part. I reviewed the balance of the propellers and went to fly. I used the ND filter for these sceenes, but I also tried without it and could not be able to find the difference...

I tested the max tilt for the GPS mode,  and it is quite fast. In Atti mode the quad makes some funny movements due to not 100% prop balance I guess. Too much wind affects as well the general behaviour, or it does this weird movements by itself...

The GoPro is in Medium FOV, but removed the fish eye in post.

Flying the Iconic X FPV

Fun flight with this quadcopter. I haven´t worked on the jello issue yet as I haven´t had many free time lately. This quad is light, fast and powerful!

One of the screws holding the GoPro platform was a bit loose and I lost it, so the platform rotated and the camera has hit with the propeller. Now the camera is not sending video live!! I´ll reset it with the factory settings and hopefully it will work again.

For better view DO NOT put full screen ;)

Iconic X FPV foldable maiden flight

This is the maiden flight with the frame Iconix X FPV foldable. I have only placed the basics (no FPV equipment yet) to test it.

The camera is placed on the front of the frame, directly over it with no anti-vibration dampeners (only the ones that come with the frame to isolate the top plate). The results, as you can see, are dreadful!! I guess this is because the old motors, whose holders are a bit bended and  produce this horrible vibrations :)

The total weight of this equipment is 1.9kg, and I have had the following flight times:

• 14 minutes with a Turnigy 3S 4000 mAh 
• 17 minutes with a Turnigy 3S 5000 mAh 

There´s something funny about two of the motors. If I attach them with more than 1 screw out of 4, the motors don't work!!! So those two motors are attached to the frame with just one screw each!

Build of the Iconic X FPV foldable

Yesterday I worked on the Iconic X FPV I bought on September. It took me some hours for this basic setup, as I have reused the motors I had before, same propellers, ESCs, the KK2 and the FrSky receiver with the Turnigy 9XR. Ready to fly!

The objective is having a better setup and probably a gimbal as well. But so far I will just see how it flyes. I need the FPV equipment also!

Contryside aerial with Tarot Iron Man 650 and Naza M Lite with GPS

V012. Recording date: 03-05-2014

After the last huge crash with the FY450, I decided to start a new project with the Tarot frame Iron Man 650, and lower kv motors, different ESCs and bigger propellers. See here the mayden flight.

In this video I test the gimbal Tarot T-2D with the new firmware (v1.5) and modified gains to try to reduce vibrations and making the tilt movements smoother (see previous post). Tiny yaw movements still pending to be improved...

It was a windy day and I could not risk to get closer to the water or to a different location, as the quad was still doing some funny movements from time to time. And because of the wind I still get some vibrations, specially when the movements are faster, or I´m not quite slow when ascending or descending.  I also reckon that using the GPS mode does not help to get rid of vibrations...

Despite of this I think the results are not bad. By the way, I can´t really make the online video look as smoother as the original one, I still need to play around with the Premiere settings in order to obtain some better footage when I upload it. Actually it looks nicer from a smaller screen :).

Some issues during the flight with the Tarot T-2D gimbal and the Naza controller

It is still a bit confusing to define the origin of some of the issues I have had for this test flight with the Tarot T-2D gimbal.

In one hand I am having vibrations in footage in two different scenarios:

• When I speed up forward
• When I tilt the gimbal up or down

Maybe it was too windy, and because of the GoPro visor and the wind resistance, the tilt suffer and fails. And I guess that speeding up produces more vibrations, but there should be a way of avoiding this. There are a lot of shoots that require high speed, and obviously there are lots of days with some wind, so there should be a way of solving these problems.

Regarding the tilt problem, I have been reading some posts that advise to install the 1.5 version to avoid the vibrations and shaking produced by the gimbal motors. 

Here you can see how to update the latest firmware (download the 1.5 version here), and this video is great to play around with you gain settings and check the behavior after that.

What I have solved for sure is the initial shaking of the gimbal motors when the quad is still on the ground, but there are still some vibrations left when moving the quad forward and backward (tilting the camera) as you can see in this video I have recorded:

I have also seen what it seems to be a general problem with the Naza controller and the barometer when the sun hits directly at the left side of the controller. I don´t know if this is my case, but just for prevention I´m using some black tape for covering its sides. This is one of the videos you will find in YouTube with this issue:

The last issue I have been experiencing, is some stability issues with some of my batteries.

KyPOM Battery 2200mAh 25C 11.1V

 When I charge them they seem to be all right (3.20v per cell). But when I fly, the quad has a high tendency to pitch, roll, or both, and It´s really difficult to control. It normally ends up in a non-soft landing. It seems those batteries are faulty, I´m following this page to try to discover what is going on...

Placing the Tarot T-2D gimbal with GoPro Hero 3 on the Iron Man 650

After the successful mayden flight of the Tarot Iron Man 650 (apart from landing!), now it is the moment of placing the Tarot T-2D gimbal with the GoPro Hero 3.

As I don´t want the propellers neither the quad legs to appear on camera, I have to place the gimbal on the front of the quad. As this unbalances the whole quadcopter, I have to redistribute some items on the top plate. This means placing the GPS of the Naza on the front, the gimbal battery on the middle, and the main battery on the bottom of the top plate.

I have set up the end point of the gimbal in the transmitter, so when the camera is looking to the front the propellers never appear on camera. But what if I lean it to the front to much because I go fast forward? and if the camera is facing down and I lean it to the right or left? In the angle is too wide then the propellers or the legs are very likely to appear on the footage. I will test it soon.

Now the weight of the quadcopter has gone up to 2,18kg with the bigger battery (Turnigy 3S 5000 mAh). I don´t spect it to fly now for 13 minutes, but hopefully it reaches 10 minutes easily.

I will put the visor as well to avoid the shadow of the motors on camera.

UPDATE:

I was not convinced about the gimbal position, so I´ve used longer tubes to place the camera further from the center of the quad. Now it is much more difficult to have the propellers on camera when going forward, or the legs when the camera is facing down and moving from side to side.

I have several batteries of 2200 mAh, that gives me just a few minutes of flight, so I have made a serial wire so I can join two of them having 4400 mAh.

I have also purchased a 45C 5200 mAh Blue Monster battery with 4S instead 3S which is what I usally use. I will test it to see the difference. I expect to have more flight time despite of the weight of the whole quad that goes now up to 2,35 kg more or less.

Because of all the mess described above, I have had to redistribute the weight so the quad is balanced. I´ve put a rear battery plate that seems to do the job.

Hopefully tomorrow is not raining and I can go out there and see what happens...

Maiden flight Tarot Iron Man 650 with Naza M Lite GPS

I coudn´t wait longer fot the maiden flight, but I´ve to admit that I was a bit scared since this is the first time I build one quadcopter from scratch.

I am impressed about how smooth the flight is with this setup. I have tested the GPS mode with course and home lock, and the Atti mode. All of them work perfectly.

I felt so confident that I tried some FPV. I think this is the first time I don´t have jello or vibrations on the real time video, with the other quad was almost permanent.

As you will see on the video, I put 3.40 in the lipo voltage alarm, and tested it to the limit to see how far I can go without loosing power. Bad idea, I had a small crash. The tubes I put for protection worked a little but not enough, as the propellers hit the ground while spinning. After this, I tried the voltage alarm at 3.50 and landing without risking.

I have flown for around 13 minutes, smooth one, with the turnigy 3S 5000mAh. Not bad I guess. For the next flight I will try with the gimbal and the GoPro to check the difference.

Aerial MTB Enduro with quadcopter

V011. Recording date: 23-03-2014

This has been the first time I shot video flying with the Naza M Lite with GPS flight controller. So in one hand I was feeling more confident in case of losing video signal or disorientation, but in the other hand I was a bit nervous because of my lack of practice with this controller.

I´m a bit disappointed because of the jello effect. As you can see, most part of it is at the beginning of the video. I´m not quite sure about the causes yet. I think it´s a mix of:

- vibrations of the motors (mainly when I go forward pretty fast)
- the propellers don´t fit exactly as they should
- I use bullet propeller holders
- maybe flying in GPS mode?
- too bright conditions with the GoPro. Under these conditions it uses a very fast shutter speed which records all the tiny high-frequency vibrations from your motors, props, etc., and causes this rolling shotter effect, or jello.

Fixing this is still a priority in my To-Do list, as I have to eliminate lot´s of shots that could be used perfectly in the final footage because of the jello. I will try to reduce part of it using a neutral density filter to reduce the shutter speed but letting through enough light for a clear picture. This is how I do it: http://niropter.blogspot.com.es/

Please check your compass is pointing in the same direction as the nose of the quad! After a bad landing, I didn´t realise it rotated almost 45º right, so it was nearly impossible to control it in the air. I still don´t know how I managed to land it. You can easily crash it and cause an accident.

Apart from that, the experience of recording a rider descending the hill at high speed has been amazing. Most part of the times I could not caught him up!

(III) Quadcopter project with frame Tarot Iron Man 650, Maytech motors 620kv,T-Motor ESCs and 13'' props - Part III

This is the third and last part of the new quadcopter project. If you haven´t see the first and second ones, you can see them here:

1. First part of the project
2. Second part of the project

I´ve finally finish the quadcopter with the frame Tarot Iron Man 650, Maytech motors 620kv, T-Motor ESCs, 13x5.5 props, Naza M Lite with GPS, the Futaba Futaba R6208SB receiver, and the Immersion RC 600mw Tx.

On the top plate I have put some velcro for the main battery so it doesn´t slide to the sides, apart from being holded with another velcro around it. The gimbal battery will go on the top plate as you can see in the pictures (yellow one, 500mAh). And also the GPS fits in the top plate and is isolated from the rest of the components.

The appearance of the quad is amazing, it looks really proffesional. It is quite big, but when you fold it completely it is really easy to carry anywhere. I guess I will try to make a do-it-yourself suitcase. In case you are interested, the measures are  100cm x 30cm x 25cm (width - heigh -  depth).

The total weight (without gimbal, battery gimbal, and GoPro) is 1.805kg.

 And now let´s go to the field and see how it goes!!

(II) Quadcopter project with frame Tarot Iron Man 650, Maytech motors 620kv,T-Motor ESCs and 13'' props - Part II

After building the first part of the project, I have progressed a bit more with the Tarot Iron Man 650. I have cut the wires of the motors to add some extra wire so they can go inside the arm tubes and reach the T-Motor 30A ESCs located on the middle plate.

I have decided to keep this middle plate as clean as possible, so I´ll only leave here the electronics (except the Naza Versatile Unit that goes underneath so it can be seen while flying). All the extra wire is laying on the bottom plate, and the batteries will go on the top plate that is not placed yet. I still don´t know where I´m placing the FPV and gimbal batteries though, and the GPS of the Naza M Lite.

There´s a couple of pieces of drinking straws to hold the Futaba R6208SB receiver antennas in place. The camera of the FPV is located on the very front of the bottom plate, between two metal pieces of the frame that fits perfectly the wide of the camera. I have put some foam under it in case it helps reducing vibrations.

So, what is next? Things pending to be done are:

• Placing the Immersion RC 600mw transmitter,
• Placing the Naza GPS unit,
• Placing the top plate for the main battery,
• Figuring out where to put the FPV and gimbal batteries,
• Soldering a T-Dean for connecting the main battery,
• Running the Naza software for the set up,
• Placing the propellers.

To be continued!!
