NanoPhan - Thrust Vectoring Nano Single Copter


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.

NanoPhan - 40mm EDF Nano Thrust Vectoring Single Copter (1 min 35 sec)


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

Thanks for watching!

Cool! Anti-torque is achieved by directing the vanes I assume? Neat gadget!

Thanks guys! Yes, everything is done with the split vectoring.

Still need to work on perfecting the PID. I have larger units that are perfect fliers. But when you go small I found out that it is very challenging to get the right setup. The servos need to react very fast and there is a significant washbowl that you need to overcome with the correct PID setting.

Gotta get high C new batteries first, before further testing...

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!

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!!!

Thanks. I agree. It feels rock solid right now. Extra weight helped the thrust vectoring to handle way better and caused a better sound with a higher RPM

To be honest, I tried to keep it as close to ground as possible because I was kinda expecting this super light ESC to fail in a longer flight like this one. However, it handled the extra amps.

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!

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.
