On another subject completely, how long, on average do people find their Phantoms take to complete start up initialisation (fast yellow flashing)?

Mine takes just over 2 mins, sometimes 3 mins.

I assume the IMU takes it's time to reach a stable operating temp.

I've found it to take at least 2 minutes, usually longer. Is the warm-up time dependent on ambient temperature?

It does seem to take a few minutes sometimes, other times it is fairly quick.

Hello all....

1st post (and not a particularly exciting one!)

First off I want to say what a brilliant thread this is.... managed to make it through the first 100 pages - and struggling to keep up! Loads of great information being shared.

I will be ordering a Phantom in the next few days. I also know I am going to want a few extra batteries for it. Looking through the thread, the only info I could glean on the internal battery bay was the following from page 13 of this thread.

"A typical 3S 2200mAH battery with XT60 connector is what we fit into our Phantom.

Battery compartment size is roughly L: 108mm x W: 36.5mm x H: 28mm"

am noting the word "roughly"... has anyone got any more precise figures for that?

Im wondering for example if this slightly higher capacity 2500mAH one would fit...
Dimensions: 113 x 35 x 33mm
http://www.hobbyking.com/hobbyking/s...y_Battery.html

if the above battery bay dimensions are accurate then the answer is "no"

my next choice would be either of the following 2.... I will probably plump for the Zippy brand, as I have read elsewhere that it might be marginally superior to Turnigy. Although I wouldnt be surprised if one is a rebadged version of the other!

http://www.hobbyking.com/hobbyking/s..._3S1P_25C.html
http://www.hobbyking.com/hobbyking/s...Lipo_Pack.html

Anyway, as a newbie to all this I just wanted to check that either of these will be compatible in terms of connectors etc. Am pretty sure they are but wanted some 3rd party insight before I order!

actually if someone could give accurate dimensions of the stock Phantom battery that would be really useful. thanks.

At a cold -10°C, mine took a full six minutes to warm up.

I'm at work, and Phantom is at home.
If you don't get answers concerning DJI lipo size and precise battery bay size before tonight, I'll post it when I get home...

On the "regular" naza the import/export buttons are on the toolbar at the top of the screen.

Battery slot is 105x35x35. I wouldn't go any larger as you will have a hard time getting the cables shoved back in to close the battery door. I bought 3 of the Turnigy 3S 2200 mah 25-35c from Hobbyking. With the Go Pro 2 attached, I get just shy of 11 minutes of flight time with them, so I am happy with that. Hope this helps.

Durability Test

I had a nasty little encounter with a tree over the weekend. My conclusion...these things are TOUGH! After getting tangled in a tree, falling 30ft, and being buried in the snow for 20 minutes, it started right up and flew like nothing ever happened. Still, I wouldn't suggest trying for yourself haha.

thanks thats a great help. I thought Id seen a 25C-35C turnigy battery for about the same money but couldnt initially find it on the site.

I take it this is the one you mean?
http://www.hobbyking.com/hobbyking/s...Lipo_Pack.html

2 further questions.

How important is the constant/peak discharge figure. I read on a LiPo FAQ that the C rating determines the theoretical time taken to discharge the battery. ie. a battery with a 20C constant discharge rating, will take 1 hour/20 = 3 mins to discharge at that rate. Given that the flight time for a Phantom is around 10 mins or so, does this mean its a waste of money looking at batteries with higher C ratings, which in theory can discharge their power more quickly? I appreciate that the higher C ratings will probably be of more use if a phantom is flown in the crazy manner I saw in an earlier video :-)

the 2nd question
How long does it take to charge a battery? Again according to the FAQ I read - which I think was written some years ago - it stated that all LiPos take 1.5 hours to charge at 1A. I believe the phantom charger has a 3A charge setting... does this mean it charges in a 3rd of the time? 30 mins? the official DJI video where it shows Colin assembling the phantom seems to imply the battery is charged in 5.5 mins... which would be most impressive. But Im willing to accept this is the "magic of TV" and its not quite that quick! :-)

Sitting on a frozen lake, ambient temperature around 20f, at 7500 feet, mine took 3 minutes.

Are you doing all of this on purpose? Your videos seem to show that you don't have the ability to fly well at all, near misses, tree crashes ??
