Hi All,
I'm looking for some opinions on what might be going on here. My "You Beaut Dinky Di Super Cheapo Car Keys" video camera has been making some odd wavey patterns and I've been trying to work out the problem.
Initially there were suggestions that the camera may be having problems tracking the fast moving frame rates or maybe it was faulty but after some experiments I'm beginning to think that the problem may be with my trojan....
Firstly, I noticed in the following video that the image was rock steady up until I started the prop when it started to get wavey:

Also, Steve was kind enough to let me stick the camera on the nose of this Thunder Tiger for a really brief curcuit. As you can see the video seems to be pretty rock solid.

So i'm starting to think that the problem may be with my plane, maybe an electrical interfearence from the Trojans electronics or something, then I see the video that I took from my flight today:

The camera was mounted on the wing, facing rearward and this time there is no waveyness until all during the initial prop spin up. It only seemed to start when I opened it up for take off. I would have thought that if it was electrical, it would have happened when the motor was spinning.
I'm thinking that it is something about the plane that the camera doesn't like but I'll be buggered if I know what that might be. If I can work out what it might be then I can have a chance at fixing it hopefully so i'm looking for any ideas as to what I can try.
