I’m thrilled to announce an addition to the drone fleet, the Autel Evo 2 Pro.  Finally technology has advanced enough for me to find a small, foldable drone to replace my huge hexacopter.  This is a bird I’ll be using for shooting RAW images and high quality 4K and even 6K video.

I debated with myself between the DJI Mavic 2 Pro and the Autel Evo 2 Pro and a few features pushed me to Autel side.  I’ve been flying this bird regularly for about two months now, and I’m thrilled with the quality of the photos and video it produces.

The range of this drone is impressive.  The flight time I’m getting crushes my hexacopter, 6x over. But it doesn’t get the 40 minutes of flight time that’s advertised by Autel.  It’s more like 30 minutes or upper 20’s.

There are still some kinks and bugs to work out for Autel and the Evo 2 Pro model.  After the last firmware update I’m getting some yaw drift.  I’m also getting occasional situations where it seems the collision avoidance system (oh, forgot to mention that) “thinks” there are objects nearby and the bird stops and hovers.

New Build: Rooster Clone Comes From 3D Printed Quad

This project has been a great, but frustrating learning experience.  I started off with the hopes of designing and printing my own 3D printed frame for a 5″ FPV quadcopter.  I originally designed it to be a 4S setup so I could use the motors I received in my last and final FPVCrate. FPVCrate is a drone part subscription service. First problem, one of the motors turned out to be bad, and I fried two separate 4in1 ESC’s.  Talk about mad!

After resolving the motor issue, I ended up switching to 6S power and discarding the 4S motors.  I went with some very cheap EMAX motors I found on closeout.  Had to wait for the slow boat from China, but the 9 motors eventually arrived.  With motors in hand I pulled all the electronics off the 4S and installed the new motors, upgrading to 6S.

The maiden flight was interesting.  It flew for about 13 seconds but something wasn’t right.  When I picked up the quad the ESC and motors were so hot they were literally melting the 3D printed frame.  I eventually concluded that the frame was not stable enough, causing micro-vibrations.  Those vibrations caused the flight controller to try to over-compensate and nearly fried the motors.

Rooster

At that point I figured a 3D printed racing drone frame was not the way to go. So I looked around and found a cheap clone Rooster frame on Amazon for $28. It was very highly rated and for good reason. It is solid.

I had two more hurdles to jump though.  During the rooster build process I found that I had one more bad motor and a defective ESC.  After replacing both the motor and ESC, the bird finally flew.

I took the quad out to a park and was thrilled to find that it really ripped was very agile.  But there was one problem left to solve, no on screen display (OSD).  At that point I realized I’d wired the camera directly to the video transmitter.

Oops.  So I had to rip the whole thing apart to rewire that part.  Another park flight is coming, but now I’m fairly sure the quad is done.
