I have no additional information beyond what has been written (by me and others) about ALTA. But their demo videos clearly show ALTA flying with large cameras on MōVIs, so one can probably infer that the payload number of 15 pounds does not include batteries. Nevertheless, we really won't know until it actually ships, which is supposed to be June. And according to my calendar, June starts on Monday.
Thanks Steve, for someone looking to make their first major investment in a professional setup; I can't take the risk of ordering one of these until I know exactly what it's capable of...is a shame because at first glance it looks like a great piece of equipment and I'd like to get involved asap. I'll keep my eye on the forum to see how it works out; I'm sure there'll be some good info once people get their hands on these. Cheers
I'll tell you the same thing I tell everybody (whether they ask or not ) which is that you should not leap directly into a heavy lift copter until you've put in a lot of time on smaller machines. There are plenty of folks out there who seem more than willing to offer up themselves and their large investments as YouTube fodder with their disastrous early (and usually final) experiences. Don't be one of them.
Thanks Steve, I agree, I've put loads of time into learning with small copters, many hours of flight practice on private land (and some public land); in varying weather conditions. I've made many modifications to squeeze the best results from a limited setup and learnt a lot in the process. I must admit I had a couple of nerve racking (early) experiences which quickly taught me the importance of a calm and considered approach to all this. I wouldn't want to deviate from the topic of the thread but I will say; the gap between amateur/hobbyist and professional safety standards for flying anything in the UK is very worrying, there is basically no safety standard on the amateur/hobbyist end...I've heard some very depressing stories that go well beyond financial loss. On the other end; the UK Civil Aviation Authority and associated companies like Euro USC international have put in place a good system with lots of emphasis on safe flying for anyone who intends to do LEGAL commercial flying.
Steve, Did you get an idea of how easy it'll be to change batteries when the gimbal is up top? Looks like it may be a bit fiddly unless there is a removable tray or something. Cheers Pete
The hardware they were showing at NAB was described as "not final". But it's likely that there will be a carriage underneath the ALTA that integrates landing legs and a battery tray. It could be the same tray that is on the top in "MōVI under" config, but probably not. Fiddly? Not sure. Logic says it shouldn't be much harder than when the tray's installed on the top. Tomorrow is June 1...hopefully all will be revealed soon.
Hello Rolf, concerning the SLS batteries, I use them on my copter and can confirm great performance - quality/price is great. Below the measures of certain SLS batteries in European units. In case the Alta will come with EC5 connectors I will just build my own interface XT90 to EC5 as I also use the batteries for my backup copter which uses XT90.

Hi Klaus: If it's not too much trouble, would you be kind enough to change your user name to your real first name and last name, please? The reasons for this (and how to do it) are explained here: http://forum.freeflysystems.com/index.php?threads/real-names.497/ Thanks Andy
Received some official information concerning ALTA payload weight, Maximum Payload: 6.8 kg (15.0 lbs) PAYLOAD WEIGHT TOP OR BOTTOM MOUNT. BATTERY WEIGHT NOT INCLUDED AND MOUNTED ON OPPOSITE SIDE FROM PAYLOAD IN TYPICAL CONFIGURATIONS. Maximum Useful Load: 9.5 kg (21.0 lbs) TOP AND BOTTOM MOUNT. INCLUDES BATTERIES. So if you go to the payload limit you can fly with maximum 2 x 10.000mAh batteries
Klaus, who sent you that information? That's very useful! But there are many battery options out there, and I don't think you'd be limited to 10000mAh LiPos. There are some 12000-16000 LiPos in the 2kg range, so you could use those, too.
Product update email from Freefly dated 22nd of June - I thought the Freefly guys put this information somewhere in the forum Can you send me an email with the link on 6S 16000 Lipos with less than 1.4 kg? Haven't seen a reliable one yet. The products I know have roughly 1.9kg for one battery.
Ah yes, but then you are above the limit with two batteries - when you use the maximum payload. Maximum Payload: 6.8 kg leaves 2.7kg budget for 2 batteries, which leads to max 1.35 kg (3.85 lbs) for one battery If you have less payload you can use higher capacity batteries of course. But then I would like to know if I have to change the Center of Gravity in the flight controller when I change position for example. Imagine that I have 2 16000 Lipos at the bottom and only a light payload could have some influence in the CoG.
Steve, do you use the MultiStars? I have a couple 4s for a smaller rig and considering the 6s for a larger build. Thanks. John

For those who haven't seen yet, Freefly just released the batteries made specifically for the Alta. Just about to order a pair... http://store.freeflysystems.com/collections/alta-accessories/products/alta-flight-pack
