Title: Doing the pattern with a camera on the plane
Post by: Mike Griffin on April 24, 2010, 10:06:48 AM
I do not know if this has been posted before but a friend of mine sent this to me. It was posted on You Tube.  I got a little nauseated and dizzy sitting in my chair watching it but it gives you the pattern from the plane's perspective.  Hope you enjoy it.

Did you also see the other videos on the site.  One there showing Paul W's flying style.  I think both have been on here before.  H^^

Did anyone, by chance, notice the rather large speed variations between climbing and diving?
I asked that question before, but it seems many people are so used to seeing this behavior, that they perceive this as constant motion.

Look again: the plane almost comes to a standstill by the time it reaches the top of loops and the timing difference between the climbing and diving parts of the squares is even visible to the naked eye. Try to count the time difference between the upper and lower parts of the vertical eights...

We've had tests here on video, taken from a judges perspective, where the constant time frame of the slowed down movie mercilessly revealed large speed variations during the manoeuvres.
The worst were the 2/4 stroke type IC engine planes, followed by the governor controlled electric ones.
The only setup that handled this (still not perfect, but way better) was electric, controlled by a G-force sensor.

Most spectators thought this plane was accelerating and slowing down, but the video proved otherwise.
