The all black one is my recently completed build, a definite improvement over the all DJI electronics on the first one I built, the one with the white arms in front. Currently setup with 5.8 video and a 2.4 radio RX, I'll be swapping the VTX and RX between them so the black ops version will be on 2.4 video and EZUHF for some longer distance flying...
Motors are iPower 2217Q and the ESCs are some that I reflashed and custom ,made a set of heatsinks for as they seemed to be getting warmer than they did before the reflashing. With them sitting up there in the propwash they're barely above ambient temp after 10 minutes of flight.

So how does it fly? Fantastic! Much better than its older brother and amazingly smooth...


Somewhat ironically I can get smoother video from this setup with fixed in place GoPro than I can my Cinestar 6 with AV130 gimbal... :(

Here's my new toy. Gonna make me nervous as hell those first few flights but hopefully it will be worth it. Thanks for all your help Kloner! Wouldn't have happened without you.

Ken, what sized props and batteries are you using with the IPower? Kloner's convinced me to get a TBS with today's exploits :)

Originally I was using Graupner 9 x 5 and it flew well. The second time out I swapped over to the 8 x 5 and it made a very noticeable difference in smoothness and stability. I'm using Turnigy 4S 5000 packs and with the current setup of the iPower 2217Q and 30amp ESCs with SimonK firmware it flys for a solid 12 minutes staying within 80% discharge on the pack.

This is the first FPV flight of Discovery #2.5 after the crash rebuild, amazingly smooth flight with this setup...

That's pretty good endurance with the 8s. Do you happen to know your AUW?

That was the very first flight after a complete rebuild from a total wreck, my bad for pushing an old battery a bit too far resulting in it falling from the sky due to lack of power. A new set of TBS frame plates and 4 Graupner props later it took to the air once again, I wanted to get at least one or two complete flights in before I started to toss it around and potentially crash it again. Here's some clips from the next two flights where I get a bit braver as the flight time increases. I think I may order another set of frame plates to have on hand and my stock of spare F450 arms needs replenishing too... ;)

Thanks! really clean, jello-free video. Any tips on isolation techniques

Good motors, good props, make sure the CG is a bit to the forward end, use either cut down earplugs or the expensive anti-vibration gel mat, I use the green one... http://www.vibrationmounts.com/RFQ/VM08009.htm

You'll get sticker shock when you look at the price for a small chunk of the stuff. If you watch the video closely you can see vibes in the hard mounted pilot cam and nothing from the GoPro so I have to say it sure does work as advertised.
