NanoPhan - Thrust Vectoring Nano Single Copter
3 Attachment(s)
This is my Thanksgiving project:

It is a tiny thrust vectoring nano single copter: Nano-Phan.

Only 102grams with a 40mm amazingly smooth fan.

It took me a while but started making progress. This video shows some indoors tests. Still testing it.


The C rating of my batteries didn't handle it so will order some high C batteries for some longer flights. Will also work on working on making it a little lighter.

Thanks for watching!

I redesigned the unit to accommodate a disc shaped fuselage.

Smaller unit is a big challenge to successfully balance in the air. Currently the servos are compensating at a very high rate. Disc shape is not something that I tested before. I am a little concerned about the aerodynamics of the forward flight.

Got high discharge batteries. Hoping to test it successfully, finalize PID and re-create a nano version of the Avrocar.

I'll post some videos if I successful.

Thanks for checking!

The avrocar project hasn't been very successful with the initial design. There was something very wrong with center of gravity that needed to be addressed. I couldn't eliminate the toilet bowl effect with my existing and new solutions that I tried.

Made a revision on the body to fix the center of gravity problem. Flies way better now and the toilet bowl effect was reduced. However, it didn't disappear. Below videos is an outdoors test, which started good but didn't end very well, with the unit losing the flight capability with a fatal wobbling.

Damage was minimal and the unit is fixed. Next step is switching from 1 battery to 2 batteries, increasing the weight and therefore increasing the effectiveness of the thrust vectoring.

All challenges resulting from the characteristics of this unique design is being magnified as the size goes smaller:)

Great experience to learn the limits of the design!


VAALLEON 12-20-2015 08:53 PM

NanoPhan Rocks!!!

The new battery configuration made a huge positive difference, combined with the longer fan body.

I also upgraded the ESC by adding a mini heatsink on it, to handle the extra weight (originally it is a superlight multirotor ESC ).

Even though I built this for indoors, I felt comfortable enough to test it outdoors. There is a slight steady wind but it didn’t stop me. This is only a balance and flight time test and I just kept hovering against a headwind but I felt comfortable enough to take it around the park if I wanted.

The flight time is a whopping +3 minutes!!!

The new face of Phan.

VAALLEON 12-25-2015 01:21 AM

The first flight videos with the new outfit. The new design restricted the airflow a little bit and added about 7 grams. This resulted in a reduced flight time, not using all the juice in the batteries offered.

So, I turned the batteries to 90 degrees to the fan axis to provide better airflow and lowered the cover to increase the airflow. You will see the pics of this configuration before the second flight. It helped but the unit still didn't complete the previously achieved flight time of 3+ minutes.

Next phase will be working on the cabling and some other things to reduce the weight and make the unit more efficient, and maybe try to find some tricks to increase the lift.

If not successful, will need to find a different solution to the looks:)

happy holidays!


birdDog 12-25-2015 02:52 AM

Looks pretty good from here. Have you ever attempted tooling around with thrust tubes (other than the vectoring) for increased exit speed? I took some Phase3 F16's to 80% and 70%FSA at 2.5 to 3x shroud dia. in length and it makes a ton of difference. This also pulls alot more amps though.
Anyhow, just curious. Merry Christmas!

VAALLEON 12-26-2015 02:25 AM

Thanks for the input birdDog! Yes the playing with the exit diameter was something that I tried a couple of times before. However, as you say, it will pull more amps and the ESC may not handle it and I don't want to go to a heavier ESC. Also that solution will reduce the flight time. Dealing with the Vertical EDF concept for a while now, I found out that the best solution is usually the one that reduces the weight and increases the efficiency. We'll see how it comes around. Merry Christmas!

VAALLEON 12-26-2015 06:35 PM

This is the new minimalist design! I decided to call this one the mosquito. It looks very much like one on the flight video.

The other improvements that I made was, making some of the cables shorter, getting rid of some bullet connectors, etc... to make it lighter.

The reason of the surface at the front is to create some lift during forward flight. It tilts forward and will give it a little uplift. I will see if I can get close to 3.5 minutes or more with forward flight.

Again, there is a pretty strong wind for this size unit but handles it well. Looks like the flight time got up to 3 min again. One thing that I need to be careful about is not to fly it backwards too fast. This is what I did at the end of the video and t kinda lost balance.

I will also increase the yaw rate and make it more responsive for tighter maneuvering.

The latest and the best design. Had to use my old camera, so the resolution is not great but it’s a freaking amazing flight from this freak!

Ok. This is the final design. It looks phreaky sweet!!! Below is a combination of a couple of flights. After the first two, I replaced the thrust vectoring nozzles with new and larger ones. The reason is that when I fly it backwards, it gets into a cyclic motion, losing altitude. I didn’t have this problem in larger units.

Large nozzles are more responsive, so it is a little wobbly in the last flight, requiring the P rate to go down a little. So, will test it tomorrow again with the new P setting to see how the new nozzles perform.

There are some close-ups in the flight video that show how the nozzles operate.

Thx bud! Getting better. This tiny unit was a real challenge but happy with the progress.

Here’s the FPV phreak! I installed a cm205 cam on it. It adds about 8grams and reduces the flight time a bit but looks good, flies even better:)


VAALLEON 01-18-2016 06:31 AM

This is the first aerial video of the 40mm unit. I am using a CM205 camera with RC305 receiver and easycap AV USB converter to record it on my computer.

The cam is a little crooked and the resolution is not all that good but not bad for the first time. I am still learning the settings on the easycap and I should be able to get a better resolution. We’ll see…


VAALLEON 01-22-2016 12:33 AM

I think this resolution is way better:

A new nano unit in the making.

VAALLEON 03-28-2016 04:43 AM

Flight video of the new Nano unit:


VAALLEON 05-20-2016 07:19 AM

Completely re-designed the Nano. Replaced the old 3S fan with a new higher kv 2S fan. Results are nice. Never felt so confident flying the Nano before. Have a problem with the power setting tho. The unit is still cutting off power during the flight…


VAALLEON 05-30-2016 06:08 AM

I had some electric problems with Nano. Towards the end of every flight, the flight controller shut down and I had some rough landings. So, I doubled the UBECs, increasing the power to 6amps but at the end of the first flight in the attached video, the unit shut down again and crashed. The new fan is amazingly powerful but pulls more amps and I think it towards the end of the flights it has been causing the voltage drop to a level that the FC had to shut down. Fortunately, didn’t have a significant damage. This time I changed tactics and added a tiny 2s lipo to the equation, powering the servos and the cam, and took out the second UBEC.

Bingo! I was able to use the last drop of juice in that battery in the second flight. With only one problem. At the beginning of the flight the new added battery came off after takeoff, hanging down from the unit. Amazingly, the unit balanced itself and I was able to land it to get ready for the last glorious flight:)

This unit is amazingly well balanced and flies very well… Fun stuff.

Nice work. Something that was not possible a few years back.

Didn't even properly test the unit yet but couldn't resist the temptation of "red on carbon"... Santa called me crazy for being up at 1 am working on this this! hohohohttps://static.rcgroups.net/forums/i...lies/smile.gif

VAALLEON 12-25-2016 09:32 PM

The outdoors maiden flight wasn’t a disaster but proved that I need to make aerodynamic and weight distribution adjustments. There is a little bit of head wind and it didn’t beat the wind. However, the new flight controller showed potential, which will make smaller units possible.

Also, no visible damage after that rough landing. Carbon fiber is doing its job!


VAALLEON 01-02-2017 06:51 PM

Getting better. First full flight without crash.... By the way I never had to fix the unit by the result of any crashes!!! After the flight the batteries balanced at 560MAH. However, they should hold 900MAH but they are old. This puts the theoretical flight time at over 3minutes, which is pretty good for this size and considering the carbon armor...

I did many flight tests with the indestructible Nano this past week, most of which ended in a crash. In the end, most of the design and flight controller issues were sorted out and the unit was domesticated, being very close to being a real Mono with very good stability and ability to reach high speeds. However, I need to change the wing design to reflect the things learned and make the unit even more durable and faster.

Before I replace the old wings, I wanted to give the condition of the unit after probably 30ish crashes, some as high as 100ft. I even hit a tree once! One crash was on the concrete and others were on grass. I never lost a servo neither an impeller, which is AMAZING! One leg was broken and fixed (which will cause a design improvement), one power cable snapped and was soldered back.

See Pics attached.

I am happy that I am almost there for the first amazingly fast and agile indestructible Mono…

VAALLEON 01-14-2017 04:09 AM

Now this flies like a real Mono:)

Installed the newly designed wings. It took me a while to re-balance it (which is a real for the smaller units) but then: boom baby!

There are 2 flights with different setups in this video. First 2 minutes is the first flight without the front wing. It flies pretty good but at 1:30 minute mark it loses balance, telling me needs a little upgrade. Then I fly it a little more until my old batteries die at 2 minute mark.

Then I installed the front wing that I use on some of my units. This flight is after 2 minute mark. It tilts better and flies really well. But this is a test and I have to push it harder and harder. At almost full stick & full horizontal at 3 minute mark it lost it. But its fine, I fly it a little longer after with some cool close passes.

Now I will calibrate the max tilt angle on the FC and we are good to put on the new batteries and have some fun!!!


VAALLEON 01-17-2017 04:00 AM

Testing the flight time with the new batteries while having a little sunset flight fun.


The flight time is a solid +3 minutes, which is really good for a nano. Flies like a dream:) I built multiple 40mm edf nano units in the past. I had all kinds of problems from low fan power to stabilization or electrical problems… In the end this way or that way all were totaled. It is ironic to me that the successful unit turned out to be a 35mm fan in a carbon armor. Feels good having this figured out in the end…

30mm EDF Mono Maya learning to stabilize in the air with the first tests. Challenging project, being the smallest Nano yet and CG restrictions trying to fit in to a sphere.

We'll see if it makes fully airborne with good maneuverability...

VAALLEON 02-09-2017 04:50 AM


VAALLEON 02-12-2017 02:23 AM

Replaced the old battery with a new one and after a couple of tests I could get a longer flight time without crashing. It still crashed in the end and broke it, but good experience was gained with this first MonoMaya prototype. I have a very good idea on the direction to go to get a real Mono out of this cute ball:)

VAALLEON 03-04-2018 11:24 PM

The new MonoMaya. This one has a 35mm EDF and a carbon fiber frame. MonoMaya is a challenging project. Airflow, heat dissipation, weight distribution and internal design are all very tricky and hard to deal with. The first try was last year these times with a 30mm EDF. I always wanted to revisit since then. The carbon frame added some weight therefore the normal 2S setup didn’t support the flight. So, I switched over to 3S and tried to make the necessary changes to deal with extra heat, etc… 3S batteries that I have are very old it’s not holding the altitude for along time. Will order some new batteries and test again.


Don Sims 03-04-2018 11:42 PM

It flew though!

Yes it did:) I found some other batteries in a little better condition and had a longer flight right after this one but lost 2 impellers to the sheet on the bed so far. Ordered the new batteries but want to change the interior settings before proceeding. Will try making it more efficient.

VAALLEON 03-24-2018 04:39 AM

I got some very inconsistent results from MonoMaya and decided to go a step back and fly it naked to make sure everything works fine. The problems that I found: 3s setup slowly fried the motor and the motor was about to give up and one of the servos was acting funny.

So, I replaced the fan and the funny servo. Recalibrated and ordered a set of new 2s batteries. Now the unit is alive and balanced. Now it’s time to build the spherical body around it.


VAALLEON 04-13-2018 07:38 AM

I have been trying to figure how to come up with a durable and light spherical body for MonoMaya since the last video weeks ago. At last I came up with this carbon fiber flex body, which I can cover with whatever I want. I got inspired by an art work that I saw at a store:)
