Hi there, which props are those in your main picture? In your list of parts you have Gemfans 2540, but the other ones look different (maybe HQs?). I'm assuming you decided on the Gemfans for better efficiency? Just curious. Thanks!

Looks amazing. How would this compare to the original GepRC Phantom? And what flight times do you get at 450 or 650 mAh?

thanks for the comment!

i have never flown factory phantom so no way to compare. also this was a winter build so no outside flytime yet just basement hovering. get 6+ minutes hover time, though for actual hard flying i only require 3 minutes

Have you tried the 8000kv motors? Did you test with a smaller lipo too, like a 450mAh?

thanks for the comment!

8000kv motors - generally i like to use the lowest kv motors that meet the design thrust specs. of course this is still on paper since the weather is not conducive to outdoor flying. once actual flight performance is assesed it may be necessary to consider higher kv.

battery - i did consider 450mah but for only ~2g more the 650mah made sense.

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..
