    Been lurking for a good while now, a year or more but figured I should start posting :p

    First off I need to take my hat off to ElGuano here, your mods and blog posts have been awesome to follow! Most of what I have done is based on your work.

    So to the meat of it

    flight time: 18:04 on a single 4400 mAh 3s2p 25c

    I decided after much reading to try and combine two of my GensAce 2200 mAh 25c LIPO batteries together for use on my DJI Phantom 1 version 1 (or 1.1 or somewhere around there)

    Currently still using the original shell though have been considering using the Phantom 2 shell as some have though wanted to rather push the current configuration further.

    I was expecting to get about 15 minutes of flight time and was ecstatic to get over 18 minutes in 15km/h winds. The gimbal still requires some fine tuning after a recent firmware upgrade.

    AUW: 1235 grams (including 4400 battery)
    Battery: 344 grams

    More videos to come on all of the mods but the basic info is:

    - Phantom 1 ver 1
    - Lots of weight reduction mods
    - Simonsays ver3 landing gear
    - Tarot T-2D 2 axis brushles gimbal
    - GopRo Hero 3 black edition
    - Custom made lens shade with ND 9 filter (2.3 grams!)
    - ImmersionRC 600mw 5.8Ghz vtx
    - ImmersionRC spironet CP antenna's
    - custom 3s 2p 4400 mAh 25c gensace lipo battery
    - Futaba T8J tx
    - HQprops 9" 9403 (yes not 9443) balanced with a custom magnetic balancer I made

    Very nice!! I can almost hit 18 min but that's using 2x 2700mAh batts w/the AUW at 1360g...I only wish I could get this down to 1235g!

    Interesting choice of props, I wonder how much they contribute to your great results. Have you tested them head-to-head with DJI's 9443's?

    I have half a set of 9443 (previously busted them) so will test at a later point when I replace them. I also have some CF 9443 copies that I could try. Would be an interesting test for sure.

    Re: 18:04 Long flight time & intro

    Thanks for the shout-out, and those are really great results with some first-rate batteries! 18min real flight on a 4400 is fantastic.

    I need to check my records but I think i hit 17.x min really running a DJI 4400 3s2p dry.

    Nowadays I'm getting about 18 minutes at 1260g with a 5400 to an honest 20% drain. So if you have a chance to run a higher cap battery, it's be awesome to see what times you can reach!

    Yep I think you were hitting 17:21 but you are also using the stripped down pmu and isod which I am not (yet)

    I think other than the isdo with pmu this quad wont see too much more in terms of modding as I will build a different style quad next :D

    Back when running 4400s my AUW was 1175-1195g as well, so you're doing it with more weight to boot. I think the Gensace are a big reason why, but as OI mentions the props may be playing a role too. Again, great results!
