Mine keep "red-lighting-out" around 12 min. that really is a great flight time.

How much are you putting back into your batteries. My guess is that it is more than 80% of their capacity. If so you are over discharging your lipos.

@Ed. I normally fly on the clock and land after the 7min buzz. I red-lighted twice which were 11:05 and 12:00 all 3s 2200mah batteries seems OK. I figure the gimbal will be flying a bit shorter. ;-)

There are many things which I dont know yet
Discharging (using) battery too much can damage battery? How too recognise best (healthy) moment to land?

Lots of things need to be improved. response is not right.
need to fix the mount so it can use the screws DJI installed in the Phantom
etc etc etc.. but its working.

Here is a quick test. video is available for download on vimeo if you want to toss it on your favorite flavor of video stabilizer software.

PS sorry about the light, its a bit dark in LA right now.

Nice. Jakubs lunar lander gimbal was my first thought as well, I have one left in stock I will have to try as well and ill order more in if this works well.

Does the gimbal still have enough clearance from the ground with the stock legs?

Oh come on. Buy a bunch of $5 LiPo's from HK, fly and if you wear out the batteries earlier than normal...just buy some more $5 packs from HK and keep flying!!!!

Van, you are right. I just bought 5 4S lipos for $9.99 per pack. I plan to fly them until they puff to the point that I cannot put them into the Phantom.

Complete noob

Hi,

I am a complete amateur with no experience whatsoever of multicopters but went with an impulse buy (to go with the Hero3 I have) of the Phantom.

It arrived today so the box was ripped open with minutes and I had everything put together (nothing complicated) within 5 mins. Then it was thumb twiddling time to wait for the battery to charge..

Quick scan of the manual and a compass calibration and I was ready to go First attempt, took off and it shot sideways into a rose bush. Took it well though and I was expecting the worst but quite robust.

Wind was gusting at about 15/ms so not ideal but I only wanted a quick hover. Anyway, waited for it to calm down a bit and tried again but started it in atti mode this time. Straight up with no problems, able to get my bearings and try the basics for about 7 mins just before it started to rain.

All in all I think it was a good purchase as I wanted to get into the hobby but wanted a simple way to learn the basics which this seems to do perfectly.

Only issue I have had is that the drivers wouldn't install on a win 8 machine (doesn't have UK English as a setting in the XML but added it and it ran). Even after running it always fails so unable to connect atm to check the firmware etc.

Will have a bit more practice before attaching the gopro but will post some vids of my noob attempts.

Thanks

Matt

I use a kitchen timer which I purchased for $1. You could use your iphone like Wheels UK did in his FPV video ealier in this thread. (Great job by the way Wheels!)

I use one of these for transmitters without a timer. Clips on your shirt or belt. Works fine and counts down the last minute in 10 second blocks.

Welcome Matt and enjoy your new toy! You did the right choice with the Phantom.
But be aware that this hobby is VERY addictive and that from now you'll have to be VERY kind with your GF (or wife)!
