Remember that reviews are subjective. Don't rely on one person’s opinion - watch multiple 'reviews' and make your own mind up. Unlike some, I don't do this to replace a day job as that makes the creative decisions all about 'getting paid'. I am free to be completely honest and clear in the videos I make. I’m not asking vendors to pay for these videos, so opinions are mine alone.

Fantastic tutorial! Thanks a bunch, Lee and Ben! 😃
Stay safe there with your families! 🖖😊
Realy nice work & brilliant tutorial (especiallky that I am working on a very simmilar T2 with most of the harware bought from Ben) ! Thank you ! However this fine tuning even nice is hard to be made only once and cover every real life scenario. Every minor change will alter the landing behaviour, especially weight. I often find myself flying my T2 on TOW ranging from ~2.2 up to 3.2 kg, and every single 100g i add changes its behaviour. Not to mention the atmospheric conditions like wind, and even air temperature and humidity that dramaticaly influences the behaviour of the model.
good info as always. that fixed wing has a very low stall speed looked very graceful even with the hedge naffing up the flare point.
That final test with the hedge wasn't intentional but made us laugh and showed a great gotcha! When things go wrong in videos, it can be more instructive than when things all go smoothly... Happy flying!
@@Painless360 wasn't having a pop at the landing it was spot on, just shows how good ardu is at reading the land and reacting to input.
Hey James, I didn't think you were. I find the videos are always more useful when a few gotchas are uncovered, often accidently!! Happy flying!
Thanks Ben and Lee for a very informative series. Appreciate the demo, walkthrough, and explanations.
The issue with hedge (in demo) would also occur if a crop, or longer grass growing on approach to the landing area. Wondering if moving the "flare point" beyond the hedge would help ensure the LiDAR is not active as flies over, so reduces the chance of a false positive height reading?
Demo shows how important the details matter in planning a landing sequence.
Hi Lee, Great video and information about Autolanding with LIDAR. Thanks for the information on how you can setup our planes. I just have one question. I see you have a CUBE in the T2, are we able to use a matek F.C ? Thanks again for the video.
Yes, but some of the latest features need the H7 processor... Happy flying
Great Video!
Did you stream the flight cam video into Mision Planner?
Yes, using the Herelink stuff. See my setup videos on it... Happy flying
There needs to be a delay so the lidar sees the height for at least 3 seconds before it flares . Give it time to get 9ver bushels and obstacles.
Check out params like LAND_FLARE_SEC. They are for more advanced users... Happy flying!
year ago I played with autolanding and inav. Just providing 2 gps approach coords and a bit of inav programming and it worked pretty stable. No lidar, no ardu is needed actually if baro sensor works properly. Auto landing was on a switch
Video on the new INAV autoland stuff coming soon. If the ground was flat, there was no wind and you guessed the distances well, the first version worked OK... Happy flying
if flying more than 20-30 minutes, the barometer pressure could change enough to cause significant differences in height reading above ground.
Ideally, having a baro sensor at landing site synced/saved before launching could be used to compensate for pressure changes over time. Unfortunately neither INAV, or Ardupilot software have a way for syncing/relaying a barometer reading from a fixed location/fixed height reading to a flying aircraft. Thus why an alternative height reference is helpful to avoiding unexpected situations.
@@AerialWaviator if you land where you start then no syncing is necessary. That's what they do in the video. Having lidar in such situation could only help a bit in the final stage to pitch up a little. And even if after 30-60 min flight changed pressure would result in 2-3m error my landing algo would still be perfectly working.
Your model is screaming bad lidar health at you. It could be because the tf mini shouldn’t be set past 7 meter max height outdoor. That read you got on the hedge could have been a misread. I noticed outdoors it tends to jump around a lot past 7m. This is documented in AP that the max height readable by the lidar shouldn’t be set to more than this outdoors. Just FYI.
Thanks for the note. This is one of those things that we may revisit in a future video... Happy flying
Just enough complication to keep me well away from experimentation with Ardupilot…
That's the power of Ardupilot. It's simple to do a basic setup. But powerful and feature rich enough to be used by professional UAV pilots... Happy flying
