Thanks - I'm very happy with it!

It's been amazing. Thanks Cliff!

On to China today!

I'm not sure I understand your question. What "other services" are you thinking of?

So am I. I hope to start working on it when I get back from the ArduPilot conference in Kaga Japan.

Thanks - yes I agree. So many uses.

Totally, I'm even more excited about what I can do with it next.

Thanks Tridge - I'm on the list to talk about it at the conference.

Hi Alex, sorry but no.Not because I failed, but because I moved and couldn't bring it with me. It can be done, my biggest mistake was too small a motor. Put a honking great motor on it and you should be fine!

@@timtheplaneman Thank you for the answer. Hope you like new place :)

@@Alex-n2g1l Oh yeah much better flying fields here.

@@timtheplaneman Still Canada, hopefully;)

@@Alex-n2g1l Oh yes!

Yeah! Love it!

Thanks Adam, I loved making it! I'm excited to see where it goes from here ... 3 or more planes? AI follow? More precision?

Thanks James - AI of course! :-)

haha! Thanks Nick! Maybe - at the same altitude is tricky. Works fine in straight flight, but turns are hard. I could definitely do 3 or more planes V formation, but I have to work on the object avoidance to do the same altitude, so I'd cascade them if I can get enough planes and pilots. 🙂

@@timtheplaneman sounds like a good challenge. Though I would say same altitude would be showing off. But desirable. 😎

Yes of course. Probably up to 250 I think.

Also you could cascade it. 3 follow planes in a 2nd row, then a 3rd row of planes following the 2nd row planes.

​@@timtheplanemanAre you serious? Amazing😅😢

@@qiotek138 Not tested, but it really only depends on the communications. I'd want to use RFD900's in "mesh" mode, or even better LTE I'm thinking.

Such a buzz. Thanks Clive!

You are right even the ArduPilot wiki here is out of date. ardupilot.org/dev/docs/building-setup-mac.html I would add that you are best to create a venv for your python.

I've been distracted working on my Plane Follow project. I hope to get back on this after the conference.

I flew more yesterday. This is a great battery. I have no evidence so far that it is fake.

I'm not going to do that. It's a great battery either way.

Because it's fake

Not fake

I haven't maxed out this battery yet. This flight used 3000mAh - but still had 13000 mAh remaining.

Thanks Bob - I'll make a note for my next video. Lots of new info.

25 minutes is only 30% used. I'm a long way from finding the max on this. Does your DJI drone weigh 7.5 kg?

Perhaps but the specs on the bottom end go way below what even Li-Ion can do.

It is a Li-Ion battery with soldi state chemistry. There are many possible chemistries with lithium out there.

@@timtheplaneman It is a Li-Ion battery with solid state chemistry. There are many possible chemistries with lithium out there.

@@wolfgangpreier9160 I am suspicious you may be right, but I need to find out more.

@@timtheplaneman Li-Ion is a descriptive name for the transport of the electric energy inside the cells. By Lithium Ions. Versus Sodium Ion or Na+ - Natrium as the correct name of the element is. Or Aluminium, Iron, Lithium/Sulfur, Magnesium , Calcium and thousands of other combinations. All of those have Ions which can be stored in a excited form and their voltage differential is used to create power by electric current times voltage on a closed loop. Lithium metal batteries still use Lithium Ions to store energy. In a Solid State Cell in the form of Ions embedded and transported via crystal web - which makes them low but very stable. In a wet environment they are transported via the liquid electroyte and separator which may be ceramic, plastic even wood (lignin) may be used. Wet cells are more combustible because the electrolyte is flammable but the electrons are floating much faster and easier with less losses through the cells. There are many thousands of possible combinations which use lithium alone. Hence the development of all new cells all the time. 99,9% are not produced more than once because they make no profit.

I'm pretty sure my current sensor isn't properly calibrated. I think it's about 3.5x so probably 42 amps with 4x VTOL motors running.

I'm not sure - would your EDF draw more than 160 Amps?

@@timtheplaneman most of the time 80 but maybe up to 120

@@Pretend_pilotFPV Look it seems to me it should work, but I have no way to test it so I hesitate to "recommend" it.

I'm pretty happy with the results.

How big would a 16000 mAh Li-Ion be? I've had a hard time finding one online to compare. I have an 8000 mAh which weighs 900g, so 2x would be just slightly bigger than this.

What I've found so far is that a 16000 mAh 6S LiPo is probably about 2kg so about 30% heavier.

2.2 kilos?? that's almost 5lbs!!

@@capnhardway I guess so, I have no idea, but this battery is only 1.5 kg so a lot lighter and therefore better. Aloha!

It's running about 260 Wh/kg based on my testing so far at about 75% the cost of a LiPo. I can't seem to find any Li-Ion comparables. Amprius doesn't list any prices or specs on their website which I find suspicious.

@@timtheplaneman Yeah I'm not saying its not a decent pack. The solid state marketing they use is misleading at best. Cycle life is never great on those either in my experience. True solid state lithium cells would be approaching 500 Wh/kg. As for Amprius, they make cells and no packs. I will say their pricing is good for what you get. Unfortunately I can't share their cell pricing. If you want to check out some packs made with Amprius cells, I can DM you a link to some very well made ones. No I don't make them for transparency but am on the commercial side of the UAV industry.

@@caphillres makes sense. I was kind of wary when I went into this hence not publishing anything till I'd tried them. I've probably done 10-15 flights now and I'm pretty happy, but more testing to come.

@@timtheplanemanI love what you do and I think it’s important to test things others might otherwise not have the ability to do before making a purchase. Keep it up!

@@caphillres Yup - more testing coming soon.

Definitely not LiIon, you can see the round cells through the covering. Everything is very "square" - and the performance results speak for themselves.

@@timtheplaneman The formfactor does not necessarily indicate the battery chemistry. LiIon does not need to be in 18650 shape to work. Both LiIon as well as LiPo are thin layers rolled or wrapped to maximize surface area. Iam not saying this battery isnt something great or not new technology, nobody knows that for sure except the manufacturers, I am still just sceptical. A cheaper, lighter battery with many properties of LiIon just sounds too good to be true.

It's solid as opposed to liquid. LiPo and Li-Ion (and Alkaline etc) batteries have a liquid or gel electrolyte. Solid state uses ... a solid electrolyte.

How much can you get a 30000mAh LiPo for?

Its and MFE (Make Fly Easy) Striver Mini - very nice plane.

MakeFlyEasy Mini Striver "Brolga" with my own custom livery!

It really is. I flew them again yesterday, they really work well.

Hey FarkHod - it's called "Telemetry Overlay" - you have to export a "Dashware" file from Mission Planner then import that into a video. Its a little bit of work, but looks great right?

@@timtheplaneman the Telemetry overlay definitely looks great! i am testing my quad tailsitter and I needed to make a video for a client just like this.

It's about 1.6kg. I might do a follow up video with all the details.

It's a MakeFlyEasy Striver Mini - I call it the "Brolga". Thanks for watching!

This battery is 10C but with 16000 capacity, 10C = 160 Amps which is about 10x the max draw on this plane even when using the VTOL motors.

On this one I am only recording. I'll be adding a SiYi A8 mini sending video over LTE, stay tuned for more interesting videos.

Oh the "OSD" is using software called Telemetry Overlay which adds the OSD elements to the video in post processing. I also used GyroFlow to stabilize the footage.

Yes I use my regular charger set to "LiPo" - 4.2V per cell is a full charge, and yes there is a standard balance lead, it's just tucked away in the shots.

I guess I'm going to have to do a follow up

USD$150 for one of these vs $200 for an equivalent LiPo.

@@timtheplaneman Plus around NZ$200 for shipping 😲 And unfortunately, I don't need anything bigger than around 8,000 mAH so they're all a little big for my sub250g craft 😛

@@timtheplaneman a litium polymer battery of the same capacity would be much bigger, heavier and much more powerful. comparing their prices like this is missing the big picture imho.

@@MarkusRessel if it's the same capacity how can it be more powerful?
