Tri-phan - thrust vectoring tri-copter by monophan


This is a prototype that I designed during long drives of a recent road trip. It’s a combination of tri-copter and MonoPhan thrust vectoring technology. The purpose is to come up with the most stable EDF powered camera platform. The unit always stays level while the thrust vectoring takes care of all directional input. No tilting at any time. I also wanted to reduce the lateral resistance therefore wind drag by keeping it level.

Never packed this much electronics, mechanics and cables in such a tight space before. 35mm EDFs powered by an amazing Genace hardcase lipo which also act as the landing gear. It took me a couple of days to tune it well enough to fly. The smaller the harder… I believe the flight time is over 5 minutes.

It has interesting flight characteristics Will work on fixing some of the lose parts to get it to some higher speeds and test the maneuverability... Ignore the date on the video. This was taken today. Thanks

Yes, I am thinking about that!

Re-assembled the unit fixing some lose parts. Flies like a charm. Not suitable for high winds and it is tiny but still beats the wind pretty well as seen in the video.

The flight time is AMAZING for a tiny EDF contraption I calculated over 7 minutes theoretical flight time, which means I can easily get more than 6:30 minutes!

Nice!
Maybe something like what I drew-up, in this post?

You have done more with ducted fans than anyone though possible. I'm so impressed. keep up the great work. I sense a product for the market coming soon.

Thank you sir! The new larger unit will have a feature that will be very interesting and even more unique Thank you for following the progress!

The maiden flight of the new 64mm TriPhan. It turned out to be a real beauty. Just wanted to hover a little bit and test the flight and the controls. Flies very well. Crash landed at the end of the flight due to hardware failure. I could swear it was ESC failure but then they didn’t even feel hot. When I got back I realized that the flight controller failed!!!

My first flight controller failure during a flight. Will replace and test again.

This unit is built to be a part of a larger project which I believe some will find very interesting. Hopefully I will make updates in the next couple of weeks.

I had a “no-drama” second flight. The new calculated flight time is around 6 minutes. I tested hover stability, some maneuvers and see how it handles, avoiding flying too high, keeping in mind the last flight’s failed FC. It looks pretty good but a little funky on the controls. I would want it a little more responsive when I am harder on the sticks. So I did a little bit more PID tuning.

Below is the 3rd flight after PID. Better handling after the PID tune. A little bit of breeze today, good for the test. Lots of people and kids around, so I cut it short. I little more tuning and I think I am ready for some higher speeds at the larger section of the park Some nice closeups where you can see the fans change angle to control the unit.

The last and a better flight with higher speeds. I reached the limit of the pitch stick once. Which means that I still have some more room to tilt the fans for higher speeds. I can keep on increasing the tilt angle and speed until I feel a significant altitude loss. I will probably go that route in the next couple of weeks and let you guys know.

Wow! This is so awesome... just another proof of concept. EDF's are good for VTOL's!

How have you done that? Do you use Open Aero VTOL?

I really would love to come into contact with you for more information about your awesome project. I really got one close to yours, but I use 4 EDF's and Wings. Would be cool to chat

So, is the torque from edf's negligible? It looks awesome.

Very nice. You have done more with EDFs that I would have thought possible.
