It was a good day last Saturday when our eagerly awaited new purchase turned up, in a massive case! When the original ALTA was first released I had wished they’d made it an octocopter. I wanted the added redundancy, stability and lift of the 8 motors I was used to. It was because it only had 6 that I decided not to take the plunge and buy one then. It turned out to be a good decision. After a few month on the market, being flown by many companies around the world, the ALTA 6 turned out to maybe not be that capable at carrying the kind of heavy payloads first advertised and the kind of payloads we generally fly (Alexa mini/Red etc), as well as having a few other teething troubles. And then about 3 weeks ago, out of the blue, Freefly System announced the arrival of the ATLA 8. All my wishes had been answered and as it was the second generation of ALTA’s it seemed Freefly had addressed the issues from the ALTA 6 and improved the design in a few subtle but very useful ways.
We bought the ALTA 8 as we potentially have a lot of foreign shoots coming up this year in wild and remote places. The ALTA 8’s ability to quickly, and very cleverly, fold down to 50% of its size and fit into its custom Peli’s case was a big draw. Its claimed flight times with heavy payloads looked very impressive too. Mainly though I’ve always wanted an ALTA as Freefly undoubtedly make some of the best UAV and gimbal products in the world and I want the fly the best! I wasn’t let down.
From the moment you get the ALTA out of its case you can see the quality of the design and build. Everything fits together so well and there are so many clever little design features that allow super easy adjustment and changes of most elements. Its water resistant and comes ready fitted with cables for your FPV system and controller setup. The ALTA comes fitted with the toad in the hole quick release system for the top and bottom battery plates as well as a quick release system for the O-ring dampening system. It takes moments to change these or change from the standard mounting of the gimbal to the very impressive sky view where the gimbal is top mounted. The ALTA seems to bring the integration and ease of the DJI’s Inspire to the big league drone.
Flying the ALTA 8 was the first time i’d flown any flight controller other than DJI’s WKM. It was a fairly easy cross over with the flight modes feeling fairly similar. What was impressive was the smoothness of the footage, its ability to handle wind, its flight time and its in flight adjustments to speed and control. On the first two test days of flying the wind was gusting up to about 30mph. The ALTA just sat in the air looking totally un affected. Judging by the footage from the Alexa mini on board you’d think there was no wind at all. Its as stable as DJI’s Zenmuse gimbals and that with zero adjustment of Freefly’s default tunings of the ALTA. The footage flying in position hold (GPS for all DJI people), was particularly impressive as you could see the ALTA getting hit by strong gusts and even at slow flying speeds there was no shake or bumps in the footage. It feels super smooth in the air and the fact the motors are so quiet you can’t hear them at all when its about 100m away is very impressive but also a bit disconcerting at first!
With my old Skyjib 8 setup carrying the same payload (and giving the same AUW) I used to get max 7-8 minutes with two 10000 Tattu batteries. With the ALTA I’m getting 12 minutes landing at 21.4v. It a massive difference. My M15/Alexa mini/Zeiss prime set up comes in at 15.6kg. This means I have another 2.5kg payload to play with until I max out the ALTA which gives me a lot of options for lenses, LCS etc.
Using the ALTA 8’s velocity clamp option on the Futaba 14SG remote was also very impressive and I can see it being very useful in the future on shoots where we are tracking cars or people and want to be able to set and keep an exact speed. You can tell the is a UAV designed by film makers.
Lastly on my test flights I tested sky view mode. It looks like it shouldn’t work as there is so much weight on top of the ALTA, even with the batteries mounted underneath adding some counterweight. I admit I was nervous testing this in the wind. Thankfully as so as the ALTA became airborne all looked very stable and my confidence was restored. This feature will definitely add a lot of creative options on future shoots and I’m sure its something directors will want use.
The ALTA is not a cheap option but you can see where your money is going. Its a new idea for me having a completely closed system compared with the custom builds of the past. The fact is, unlike a lot of UAV manufacturers, I trust Freefly. We’ve been using the Movi for years without any issues and it revolutionised the stability of filming from an aerial platform. The ALTA is a huge step forward in UAV design for aerial filming and its nice to be using a flight controller where you haven’t heard a hundred stories about it failing mid flight! It was a big investment buying the ALTA but I am already so glad i did invest and when I’m doing flight after flight in various remote parts of the world later in the year I’m sure i’ll be even happier Im flying with the ALTA!
