    You guys think I might have any problems putting these these 2 components so close to each other? Don't really know how noisy either of them are but I imagine a fair amount of noise comes off an esc. Any thoughts are appreciated!

    500 kv on 6s is to low of kv. On 6s you need 700 or more kv. I found the lower kV just was not as efficient as my 950 on 5s. If 6s was a good spot I would have gone 6s. I found no real gain on 6s over 5s of the same weight

    You could tell Johnny was fighting to keep his Drak in the air during that launch. I think at 500kv on 6s with a 12" prop and a 50amp esc, he's going to find out his power system just isn't going to work well with this frame.

    Guys I'm gonna use the Drak for long range flight around 20km distance, which setup is better using the SS motor, 4s or 5s and prop ? for best efficiency.

    for high efficiency its better to use a speed-propeller but thats not easy to lounch. starting with bungee would be the only safe method.
    i am going to use this bayby für my drak#1: http://www.reisenauer.de/artikeldetails.php5?aid=1547 it 18x23 Speed and will be used with the reisenauer supercief engine http://www.reisenauer.de/artikeldetails.php5?aid=1916 having cruise-speed about 120kmh with less than halve throttle.
    we will se if my enging back of service.
    I am using 6s5000mAh and 6S10000mAh and 100A YEP-ESC.

    for propeller less than 15" which can be used with original verticals you need other engine, for example: http://www.reisenauer.de/artikeldetails.php5?aid=1919 and http://www.reisenauer.de/artikeldetails.php5?aid=652

    i Think Stock-Motor with optimal speed-propeller would although work verry well and is much more cheaper.
    Maybe this would work wit Stockmotor: http://www.reisenauer.de/artikeldetails.php5?aid=1633 or http://www.reisenauer.de/artikeldetails.php5?aid=2092

    Sometimes you can't avoid mounting things near each other and as a general rule of thumb just make sure you maximize the distance between them. Maybe turn the ESC sideways and push it all the way back and move the Vector toward the front a little more. Many times just an inch can make a big difference. Just my 2 cents since you asked.

    i got the CFK-Axis and bearings today and make pictures to understand the planed mounting.
    one bearing at each side would be definitly not enough.

    The Bearings will glued into 14mm U-Profile, the 30x30mm angle will be glued into the fuslage like picture with red arrow.

    I think i will use the V2A Axis instead of CFK. I can twist the cfk-axis with much force with my hands, V2A never without tools.
    And because of needed additional wight in front no problem if little more wight.

    @shifteer it depends on the ESC but at the most: Throttle to much speed, connect and wait about some sound and swith throttle to zero and other sound will tell you brake on or off. but better to read the manual bevor doing this.
