In neuroscience, the visual P200 or P2 is a waveform component or feature of the event-related potential (ERP) measured at the human scalp. Like other potential changes measurable from the scalp, this effect is believed to reflect the post-synaptic activity of a specific neural process. The P2 component, also known as the P200, is so named because it is a positive going electrical potential that peaks at about 200 milliseconds (varying between about 150 and 275 ms) after the onset of some external stimulus . The distribution of this component in the brain, as measured by electrodes placed across the scalp, is located around the centro-frontal and the parieto-occipital region. It is generally found to be maximal around the vertex (frontal region) of the scalp, however there have been some topographical differences noted in ERP studies of the P2 in different experimental conditions.
Research on the visual P2 is at an early stage compared to other more established ERP components and there is much that we still do not know about it. Part of the difficulty of clearly characterizing this component is that it appears to be modulated by a large and diverse number of cognitive tasks. Functionally, there seems to be partial agreement amongst researchers in the field of cognitive neuroscience that the P2 represents some aspect of higher-order perceptual processing, modulated by attention. It is known that the P2 is typically elicited as part of the normal response to visual stimuli and has been studied in relation to visual search and attention, language context information, and memory and repetition effects. The amplitude of the peak of the waveform may be modulated by many different aspects of visual stimuli, which allow it to be used for studies of visual cognition and disease. In general, the P2 may be a part of cognitive matching system that compares sensory inputs with stored memory.
Hopefully this helps you get your P200 (or 175) in the air! Some settings may differ based on your receiver and or preferences. Stay tuned for the second flight video when it is fully tuned, then on to 4S!

This fast little racer is very durable to crashes. Watch as I demonstrate ;-) Buy it here http://shrsl.com/?dh2y Pros - Skyline32 flight controller fully configurable with Cleanflight. But it flies great right out of the box with its stock settings. - Transmitter also programmed ready to go out of the box. - Fantastic punch acceleration and maneuverability (sans GoPro) - Seems to be a very sturdy CF frame. VERY crash resistant as demonstrated in this video. - Configurable beeper and LED lights - 800 TVL FPV camera - 5.8G 48CH 600mW Transmitter - Camouflage props! Cons - The original transmitter that came with my P200 was defective, and resulted in a crash and unusual commands to the quadcopter. But binding a duplicate transmitter that came with my P175 corrected all these issues. -...
In deze vergelijkingsvideo werd het toch al snel duidelijk, de Colour Salute Extra Laut was de overduidelijke winnaar. Maar dit is ook wel te merken aan de prijs. Voor het budget zou ik kiezen voor de Colour Salutes, of de Dum Bums!
Find it here for $215: http://goo.gl/gwYeiv This is an amazingly powerful drone, with a great range and very high quality camera. Flight is stable and sporty, with a serious punch. A great racing drone for beginners to pros.

My 2nd Quadcopter Review! Thank you www.banggood.com This time it's the JJRC P200 Racing Quad, please watch the video to see how she flies! ***update*** The switch shown at (04:15) is actually a VTX power output switch! Another great feature especially if you are flying with friends or meeting VTX power output regulations! Thanks to SeByDocKy from RCGroups for this information! The rcgroups thread can be found here: http://www.rcgroups.com/forums/showthread.php?t=2702984 Find it at www.banggood.com!

Which would win in a fight? Depends on the situation, of course, but I prefer the sound of the USP-S, which is obviously the most important thing... 0:00 - Intro 0:10 - Ammo capacity 0:16 - Damage and accuracy 0:44 - Accuracy comparison (pictures) 1:18 - Suppressor removed - differences 1:34 - Fire-rate (Inconclusive) 1:48 - Penetration (HAHAHAHHA) 1:56 - Noise 2:11 - My conclusion 2:21 - Low ammo comments 2:45 - Length of gun Summarised: P2000 - More ammo - One extra shot per clip - No silencer distraction - Shorter weapon (Can't be seen around corners as much) USP-S - Quieter - More accurate - Looks awesome You decide.

This new P200 looks very promising! I am generally impressed with the components they included for such a low price,including the red bottoms, multishot capable escs, and the build quality it self seems very good so far. Of course there are bad things though, 3s battery, 2 blade props, and structural PDB (and the stupid battery tray). I have very high expectations for this one though so stay tuned for the beginner setup, then an advanced one!

I just wanna be your ball and chain
Wrapped around your finger
Locked up, tied me down
Follow you forever
Never let you get away,
Holding on like a ball and chain
I never wanted to stay
In one place too long
Oh no, not me, I didn't wanna be
A victim of that fatal touch
When you want someone too much but
You, you'll be the end of me
And I don't want to hurt anymore
I tried my best to avoid
Making promises
Oh, no, not me, I didn't wanna
be a prisoner of that tender trap
When there's no turning back but
You, you got me on my knees
And I won't be afraid anymore
I just wanna be your ball and chain
Wrapped around your finger
Locked up, tied me down
Follow you forever
Never let you get away,
Holding on like a ball and chain
I know it's been some time confined to be alone
but I know I found the one who's gotts be this love jones
you know that I get open when you rubbing my back the goose bumps
and chills must be proof of that cos I'm feeling when your dealing
all the knowledge you've got about making it good
when your touching my spots I've goy lots of loving
when we bubbling it right I look forward to the time the day turns night
you've gotta meet me at the crib for the quarter to nine
and at the time love devine and what do I find
I won't be afraid anymore
The side of you be wanting me just haunting my fight boy be my ball and chain yo it's gotta be right
I just wanna be your ball and chain
Wrapped around your finger
Locked up, tied me down
Follow you forever
Never let you get away,
