Re: [RCSE] Continuous Loop Winch? Neither dogs or rabbits fly!

The motors and accessories for Injoy are great. One major difference between the two applications is that the rabbit (or the dogs) do not leave the ground. The extra 750 feet of loose tow line flowing through the turn around would be a major problem. Vehicle towing is great where you have the run out room for the vehicle, but like F3J you have little control after the process is started. Some of my club members have tried almost everything, down to a remote control car pulling a hand launched model. It worked until the wheels were lifted from the ground by the model. So I guess there is no free lunch. If you want to fly, you must have some equipment to do it with. Don RichmondSan Diego, CA (Virginia Beach, VA in the rain)[EMAIL PROTECTED]hilaunch.com
Re: [RCSE] Continuous Loop Winch?
I remember an article in Model Builder or RCM many years ago where they did a setup like that. The major problem to solve was the extra line drag on the ground. This was waaay back before Rahm was making winches, and before retrievers were in widespread use. Doc
Re: [RCSE] Continuous Loop Winch?
I guess the first problems that come to mind are: -The tow lines getting tangled in the turnaround and the winch each time it passes those points. -Fixing line breaks...The length of the line is critical. I guess a strap of some kind could be used from winch to turnaround and back that is far stronger than the tow line. I don't know, just a thought. -Line drag??? Is it an issue? Could guide rings be placed along the length of the returning line to keep it off the ground? I don't know. I may be w off base. Just my first thoughts.

Mike I saw a similar system at a contest in Lakeland Florida back in 1974. Worked great until one of the towlines wrapped around the ground line loop. You never saw such a mess and we spent more time waiting for the lines to be untangled than we spent flying. Chuck Anderson RCSE-List facilities provided by Model Airplane News.
