✈ It's Beautiful Inside - The Collapsed Cave Challenge
https://youtu.be/zALrT5vPRKc

There is this collapsed cave up in the cliffs, kind of a rock bridge. I was speculating since quite some time whether I should try to fly through it or not. I was thinking there might be a blind spot where I could lose the video signal just when passing through the critical passage and possibly leaving me with a crashed drone in a spot difficult to reach (I'm not a climber). Well, it turned out there is no blind spot and I can easily buzz through the fucking cave! :-)

Is there some kind of device on the drone that warns you if you are close to an obstacle? I am always amazed at how seemingly close you get to things without crashing. Or is it just a case of having a lot of experience and being able to judge distance?

Also, is the above a complete parts list to get a working drone? What do you use as a controller and vr goggles? Also, what is the flight time, out of curiosity? I have a an AR Drone that I bought for like $300 a few years ago and was so disappointed by how fast the battery discharged and the fact that it was out of range when only barely across the lawn that I stuck it in the closet and haven't gotten it out since.

I don't have any collision detection system on the drone, it's all flown manually. The parts list is complete just for the drone. On the ground I'm using the [FrSky Taranis X9D+ Transmitter](https://www.banggood.com/Original-FrSky-2_4G-16CH-ACCST-Taranis-X9D-Plus-Transmitter-Carton-Package-p-1121799.html?rmmds=search) with the [TBS Crossfire radio system](http://team-blacksheep.com/products/prod:crossfire_tx) and the [Fatshark HD goggles](https://www.fatshark.com/product/dominator-hd-v3-fpv-headset-goggles/) with the [Furious True-D V3.5 Diversity Receiver](https://www.banggood.com/Furious-True-D-V3_5-5_8G-40CH-Diversity-Receiver-System-Firmware-3_2-For-Fatshark-Goggles-p-1170232.html?rmmds=detail-top-buytogether) + [2 antennas.](https://www.banggood.com/ImmersionRC-SpiroNET-V2-5_8GHz-LHCP-Diversity-Bundle-Omni-8dBi-Patch-FPV-Antenna-w-45-Degree-SMA-p-1257486.html?rmmds=search&cur_warehouse=HK)

With this setup I have flight times up to 7 minutes, depending how I fly. However, I'm not going to re-build my other drone with different motors and larger props to get flight times up to 15 or more minutes.

Thanks for the info. I think that I have enough to get going. It looks like it is much cheaper to build with parts than to buy a fully assembled high end drone.  Much appreciated!
