I use a Cam Shot HT10 which appears to only be available from Race Recall here in Australia (just google their name) it was a bargain at $199 including free express postage. Comes with tonnes of moutning gear, head straps etc however the headset mount was a DIY job out of the gear I was supplied with. I can give you some pictures if you want. The camera has a 120 degree wide angle lense, runs on an SD card of up to 32GB (4GB gave me 1.2hrs recording), comes with a long life lithium battery, waterproof for up to 10m so you can take it swimming. Disadvantages are the camera is fairly large when it looks small on the website, it is headset mountable but I need to redesign my mount so it's lower for the Gazelle, the Jabiru won't be a problem. It's by far the best deal you'll get for a sporting camera and its quality is reasonable. GoPro is like $300AUD for just the camera and the ContourHD is something like $450AUD for the camera and mounts are on top of that.
Pud explained it all pretty clearly. The Super Light Aircraft Club of WA leases the land from the AG college and has ~31 hangars, the club also allows a flying school to operate, TopFun Aviation. The full length of the strip is not useable, however it is landable in the case of an emergency. Strip length is 800m usable with 600m unusable I *think* Also gives you loads of extra room incase of an EFATO.
I'll probably be there the next two Saturdays and I think Bob is also there most weekends (I usually see him on Sundays)
