Thanks. yes, it did pretty well. I never tested it in this kind of wind before and I was scared that the unit would go out of control because of over or under compensating.

I can tune it a little tighter but I am kinda mentally done with tuning this for a while. I think it is reliable enough to do some FPV tests. I want to see how comfortable I will feel closing up to some objects.

Re: Tri-phan - thrust vectoring tri-copter by monophan

What is your flight time? Do the EDF's not use more power?

Yes, they do. This unit flies around 6-7 minutes.

Decided to have some fun with this. It was a handsome unit as it was. So, I wanted to see how it would look like with some boost.

Re: Tri-phan - thrust vectoring tri-copter by monophan

A better flight video in the daylight. I really like the looks of this bad boy. I’ll keep this as the best looking unit I ever created. Even my wife liked it… for the first time in 5 years that I have been building😊

Re: Tri-phan - thrust vectoring tri-copter by monophan

TriGami This is a 100% foamboard construction from my MonoPhan origami series. It is arduino supported and can either be navigated without tilting only with thrust vectoring like my older TriPhan units, or it can fly just like any other tricopter, via differential thrust. This was one of the hardest units to tune. Outdoors maiden, 5 short flights with different settings…
Flight #1 & 2: Rough tuning, PID too tight. You can see the unit nose diving when I cut the throttle during the flight, which means that its grossly nose heavy. The ESC calibration is off.
Flight #3: ESCs calibrated, PID eased off, unit weight balanced: 100% thrust vectoring navigation, a tiny bit of differential thrust to support. Pretty stable but not very responsive.
Flight #4: 50% thrust vectoring navigation, increased differential thrust (hybrid). Unit more responsive but not very stable.
Flight #5: No thrust vectoring (except yaw), pitch and roll controlled with differential thrust. Wobbling due to increased leveling input. I am not confident at all, land the unit early.

Need to further tune PID and find the right setting.

Re: Tri-phan - thrust vectoring tri-copter by monophan

I had tens of tests, PID variations, ESC replacements, crashes... I totaled the old unit and re-built trying to fix all design issues, adding carbon fiber enforcements, changing the servo drive method, etc. If I went through all issues it would take a couple of paces... Anyway, at last, the unit flies like a dream. It is probably more stable and smooth than anything else I flew. This is a short, first fully successful test. More videos to follow...

Re: Tri-phan - thrust vectoring tri-copter by monophan

Getting the unit dialed at last... Strong winds today. The unit flies really good. I switched back and forth between thrust vectoring to differential flight a couple of times during the flight. Optical flow works but was unable to compensate the wind push. I will increase the compensation and try again.

Re: Tri-phan - thrust vectoring tri-copter by monophan

At last I can rely on this unit not to fall out of sky and have some fun… It is a little wobbly and has some servo oscillation but I really like it like that. I think it gives the unit character😊
The flight begins with a flight with differential thrust, then I switch ch 5 to mid and it switches to thrust vectoring. It is a little slower response but still flies really good. Then ch 5 low activates optical flow and baro. There is a nice close-up that show how the servos compensate and keep the unit in place. The wind is not strong but you can certainly feel it.

The best part is this unit excites me and makes me want to fly more, and push it further… Everything works perfectly and nothing heats up, except the battery… Buying this battery was a mistake…

Re: Tri-phan - thrust vectoring tri-copter by monophan

Not built for accuracy but lots of fun… Some wobbles and jitters but gets the job done perfectly.
Ch5 high: pitch and roll differential thrust, yaw thrust vectoring
Ch5 mid: pitch, roll and yaw thrust vectoring, minimal tilt. MonoPhan thrust vectoring algotithm.
Ch5 low: pitch, roll and yaw thrust vectoring, optical flow position hold and BARO. No tilt… Arduino supported.
Fully foamboard with carbon fiber and aluminum enforcements.
Thanks!
