Just uploaded youtube of my latest attempt at getting some interesting Legal Eagle Perspective on video. I wish we had calm weather here, maybe in late October or little later. Working on version 6 of chase cam so hope it will be more stable. I saw something at Oshkosh in 2012 that caught my eye when a powered parachute took off with a chase cam. Have thought about it ever since and at Oshkosh this year met John Vinning, the power parachute flyer and saw his videos, saw his chase cam and decided it had to be tried. It is not as simple behind, more off to the side, do not want to get it into prop wash, started with something similar to what John uses then have modified and made two more from scratch. Modified each several times. I believe if air was calm could do a lot better but next version will have compensation and eliminate the rolling.

cheers Paul

Les- Very cool. What a great perspective. How many pounds test is your fishing line?;). Rich.

I have seen one way to make a drogue out of a styro cup and foam wings but I am cheating and using one of those cheap foam gliders from Hobby Town USA...I will pull it first with my RC plane and see if it works....Hope it doesn't do a death spiral!

General information about chase cams, follower cams
DO THIS AT YOUR OWN RISK.
1. Safety has to be a primary concern. If the camera catches on something it needs to break away easily so it does take the flying machine down.
Always think about the people, animals objects on ground that may be injured if the camera comes loose or drops.
2. From what i have learned so far keep it light, lighter the better.
3. Test it out a vehicle window at the speeds we are flying for stability and control. If it does not remain in one piece and stable at 60 mph out car window why would it stay together or fly better behind our flying machines. This also gives an idea of forces on tow rope or fishing line involved.
4. Don't get lost in working with the camera or chase cam and forget to fly.
5. With the chase cams i have worked with, working on model 10 now, pull forces are very light. started with 1/8" nylon rope and then tried braided fishing line, went back tot he 1/8" nylon rope. Reason changed back is the braided fishing line does not stretch and transmits the vibrations from air frame into chase cam and it does not help raise the chase cam. The rope has some flex and flies in the wind which helps raise the camera and dampen vibrations.
6. For safety link i am using two light round wire key rings, one rope and one on the chase cam connection.
I have lots more to learn, things that i thought would work have not or not improved, i believe with model 10 i am getting close and with 2 or 3 more flights should be able to get camera up to follow in place of fly below. flying below has possibilities but when in close to something or low to ground or fence could be a problem. My goal is about 5 feet below me.
