In-Flight videos on YouTube

[Bob Reeves]

Some of you may remember back in 2003 (Long before GoPro) the Tulsa Gluedobbers made several attempts to attach a camera to a Control Line Airplane and record videos of the flights. At the time the only affordable technology available was a camera with a cobbled together video RF link. We ran a VHS recorder off an inverter to record the video to tape. Fast forward a few years and we had one of the tapes converted to CD.  I pulled the two most relevant flights off the DVD and uploaded them to YouTube. The videos were done with me flying the pattern using my TwistMaster powered by a Saito 40.

These two flights are the full pattern, quality isn't that great but still worth watching. Pretty sure these are the first ever recordings of a camera on a control line airplane.
 
This one shows how gravity and centrifugal force effects fuel in the tank during the pattern maneuvers


shows just how much control surface deflection is needed to fly the pattern.

I love it. I was surprised  that the fuel did not rise up the side of the tank more and how many times the clunk actually comes out of the fuel.  What might be useful is to point the camera just a bit more at the flap/fuselage joint and put some tape strips at say 15, 30,45 so we can tell the actual deflection.  This is so cool - Thanks

   I recall when you first did  these, it was/is fantastic. The most surprising thing to me was that the fuel more-or-less reaches a static position nearly immediately when the acceleration changes, IOW that the dynamics of the fuel were much faster than the typical "forcing functions" and highly damped. For most purposes, you can just calculate the fuel surface orientation from the vector sum of the acceleration, and it gives you essentially the right answer. You can immediately tell, for example, that the angle of the wedge on the Veco T-21 series is a bit to shallow to ensure the fuel stays at the pickup at the end of the flight, which is just what seemed to happen in practice, and just what you would predict from a simple calculation of the fuel surface orientation
