11. Into the Bloom – Part II

Previously: Catching a blooming cacti – part I

I knew that skipping a couple of weeks will pose a problem for finding blooming cacti but it was better than nothing. So ,two weeks later, with a fixed gimbal and much more motivation I went on to continue my hunt for last-chance of a blooming cacti.

Riding all the way east on Via Linda I found a trail that I heard of before, The Sunrise Trail but being the lazy fat dude I am, I’ve never got here for the same reasons as some of my healthier friends did. My friends are usually sending slefies from the top of this trail at 5am in the morning, which is about 2 hours after I went to sleep…

But now that I have my flying proxy to do the hard work for me, all I have to do is climb the trail just enough to be able to see where my quad is, so I can get a good idea of how to fly it…

Starting the usual pre-flight checks:

  • Power? On
  • GPS? On
  • Status lights? Blinking Green
  • Camera? Rolling
  • Remote switches? Check
  • Visual examination? … FAIL!

It seems that one of the landing gear legs has a serious dent, nothing too crazy but enough to make a mental note to self: need to order a new landing gear.

We are ready to go…

Starting the engines, pushing the throttle stick up… and off we go…

The heat is even higher this late afternoon, than two weeks ago, and my ability to control the drone is diminished dramatically…

Nevertheless I manage to fly it towards the top of the mountain so that I can also take a selfie of my own…

And off we go to find what I came here for… some blooming cacti….

I spot a couple of them, trying to fly towards them and have some interesting shots, hoping to not lose my drone down the creek that hosts the only two blooming cacti I was able to spot.

I manage to maneuver towards one of them, while hopefully capturing some nice ascending and descending flight shots over the creek.

Despite the hot weather that, as I already mentioned, makes it hard to control the quad, I decide to do something crazy and fly it in between the two “hands” of the cactus. I approach it “smoothly” trying to stay focused on the blooming flowers while flying through the cactus’ structure, and… BOOM, BOOM, BANG!

I hit the cactus. Now, I’m at the grace of the stabilizing software to take me out of this situation without going down the creek to search for my quad. Best acquired instinct at this point is to “let go” of the controls and see if it can adjust itself…

Few more bounces into the cactus and, it flies out of the risky area and is free again.

I resume control over the drone, take some additional shots and bringing it back for landing just before it runs out of juice.

Second round  of juice is loaded and I’m trying to take off again…

And then this happens

I have no idea why but a quick look at it shows that the only damage is that same broken landing leg which got a bit loser, but still  attached “enough” to the quad, so I give it a thumbs-up to keep flying.

Set it for a second take off and this time we are good.

I empty the battery and drive up to the other side of the road to take my final set of shots down in the bigger creek on the southern side of the access road.

While I was prepping the drone for take off, I was proud of myself for the amount of walking I did to get to the bottom of the creek. With a huge smile on my face and even huger sweat spot on my shirt, I’m starting the motors and bring the quad to mid-air.

I capture some nice shots flying up the side walls of the creek, and then I decide to try something a bit different and fly inside the creek’s path in higher speed than usual.

I start accelerating and the creek is turning left, but not surprising, I can’t keep up with my drone, by means of running, so I just trust my instincts and send it left while I’m chasing it to be able to see where it is.

Before I know it, it runs into a crowded pile of dead trees and dry bushes and makes a grand flip and crashes into the floor.

My first real crash since I started flying this toy.

I find my way through the dry shrubs hoping to not make this my first official meeting with one of the local residents of the desert, the rattle snake…

I’m making sure my phone is within reach, just in case I need to make an emergency call… and I’m digging in to grab my quad, which is laying on its back with the gimbal helplessly attempting to stabilize the camera, which makes it look like as if the quad is gasping for air and the camera is its pounding heart…

I pick it up,  while cursing a bit, quick inspection, the battery door is open and the dented leg looks even worse than before… no doubt I’ll need a new landing gear. I walk it back to a safer place, put it back on its 3.5 legs and try to fly it for the last time, before I’m out of juice.

I get some last shots of a couple of other cacti that had some final touches of blooming flowers, and we are out of juice…

By the time I got home the landing gear was barely attached to the drone.

Ok, Amazon, here I come: A new Landing Skid is on its way…

So here is the last take of blooming cacti I could get before it was too late…

 

 

 

10. Into the Bloom – Part I

Previously: Dealing with the fear of water

Ever since my last fly over the water of lake Margruite in Scottsdale, I was looking for my next opportunity to fly.

Unfortunately, I didn’t get a chance to do that for four weeks.

Don’t get me wrong, I did have the intention and made the necessary plans, but ‘reality’ was not on my side (no, ‘reality’ is not how I call my wife and daughter…).

I even brought my drone with me to our short trip to LA hoping to catch some nice views…

My drone stayed put the entire round trip until we got back from LA. Well, almost in the same position. 5 minutes into the ride my daughter informed me that if this “thing” in the back seat will not stop “clicking”, she will teach it how to fly out the window, so I had to stop and rearrange the bungee cords to hold the gimbal in place so its metal parts stop hitting each other in loud metallic sound.

During the visit, every time I dared to think: “This is the perfect time to fly it”, either my wife or my daughter (I guess I do call them ‘reality’) had a convincing reason for why I shouldn’t stop the car to fly it at that specific moment.

I really wanted to fly it next to the power windmills in Palm Springs but,  “surprisingly”, the winds in the area were too strong (now I know why they chose this area to install them) and it was too cloudy to get a good picture anyhow.

OLYMPUS DIGITAL CAMERA

Of course this is when my wife and daughter said it would be ok if I’ll fly it now… twisted reality…

When we got back home, I had to crawl into the back of the car to detach the poor plastic bird off the back seat and bring it home, without giving it a chance to fly during the entire trip.

I felt like I have to correct this, so the following Sunday, I cleared my schedule to find the time to fly it.

By the time I got things going it was close to noon. In the desert, ‘close to noon’ during summer can mean 3 digits temperatures of about ~104ºF (~ 40ºC for my metric friends), but this mid-May  Sunday noon was already showing these high temperatures earlier than expected.

The good news about this time of year in the desert is that you get to watch the blooming of the cacti. If you never seen a blooming cactus, you better not say you lived in the desert. This is one of the most beautiful phenomenons of the desert view. Seeing these tall Sonora Saguaro cacti rising to an impressive 40-60 feet (12-18m), with a bright cluster of flowers at the top, is one surprise  that is waiting for any new desert resident (sorry for ruining the surprise to any future desert residents…)

So I decided to dedicate my next shooting to this beautiful act of nature.

Finding cacti in the desert is quite easy, you just need to walk in any direction for 5 minutes and you’ll hit one. But finding a blooming one can be quite tricky if you missed the peak of the season which last only a few weeks, which of course is what happened to me.

So I’m in my car, scouting for blooming cacti and as I drive I notice a few on side of Frank Lloyd Wright road just a few miles before it ends.

I stopped my car in one of the first exits, and got ready to fly.

Quick pre-flight check:

  • RC On: Check
  • GPS ON: Check
  • IOC Off: Check
  • GoPro On: Check
  • GoPro Recording: Check
  • Battery plugged: Check
  • 6-tone sound effect: Check
  • Gimbal stabilized: Check …. Uncheck…. FAIL!

I scratch my head, why is my camera pointing to the floor? oh… maybe the tilt control is down…

  • Tilt Control up: Check
  • Gimbal Stabilized: FAIL!

$H1T! what do I do? Like any good software engineer, I look for the quickest way to: “restart”… Now I understand why they have this little plug between the gimbal and the quad, so I can reset it by quickly unplugging and plugging it back in.

I unplug, count to 5 (like in any troubleshooting guide) and plug it back in.

A second later the gimbal does its initialization and the camera is …. stable… well sort of…. but stable enough for me to fly it…. I know that something is wrong but I don’t know what yet…

I run a quick pre-flight-check again, all seems good, except for the crooked camera, but hey, these flowers will not wait for ever….

I take off, flying over FLW trying to get to the cacti on the other side of the road, having the worst angle to do any decent guessing on the actual position of the camera relative to the one cacti that is blooming, but hey, I’m thinking of all the poor people who are actually hiking in this weather, and I’m immediately appreciative of the easy hobby I chose.

The entire flight the drone is “fighting” my attempts to control it, although the wind is very light, and it reminds me of the times when my children were 3 yrs old and I was trying to convince them that it is time to go back home from the park, while they keep running through my fingers and returning to the swings…

Without any other option I force the drone to land next to me, and we are off. I could swear that the flight time was shorter than usual but I’m not sure. I get to the drone, picking it up from one of its arms, turn the GoPro off, and I realized an overwhelming sharp burn in my arm. I almost dropped my baby before I realized my arm touched one of the motors. It took me less than 1 second to realize what happened. The motors had their first ‘welcome to Arizona’ flight ever, and they didn’t like the heat, so they were fighting back by producing counter heat! That was HOT!

I kept looking for more cacti to shoot, found a couple of other locations and since one of them was next to a nice green area, I decided to use it to practice some flight maneuvers in that area.

I realized that shooting without watching what you shoot, brings us back to the old film days where you had to wait for your film to be developed before you could watch it. So, when I got back home and went through the ‘digital development process’ (copying the files to my computer) I could finally review my footage.

The good news, no “burnt-film on my memory card”, but the bad news were that there was a reason to my bird’s madness. It seems that my gimbal over-rotated and got its wires tangled which caused its motors to over-fight gravity.

gimbal-tangled-wires

This explains it all… The Gimbal’s brain was trying endlessly to adjust the camera, but the motors got blocked by the wires and therefore the camera kept rattling and the footage came out fuzzy and jumpy.

I managed to get only a few seconds of stable video… nothing close to what I wanted… but here you go…

Luckily I had about one more week before it is too late to find the blooming cacti… maybe next week would be more successful?
