Guest flightline Posted July 30, 2003 Report Share Posted July 30, 2003 Bought a home-made dead bird flapper and added an on/off switch. Used it for first time on Sunday and the battery (which is new, 12v 7amp and fully charged before starting) ran down fully after about 11/2hrs. I think it was the volts drop occasioned by the 25m 3 core lead to the hide, where I also had the battery. What did I do wrong and how can I enable the flapper just to flap when I want it to? Any advice appreciated. Quote Link to comment Share on other sites More sharing options...
highdowns hunter Posted July 30, 2003 Report Share Posted July 30, 2003 Flightline why dont you ask at a model shop you may be able to buy a remote controlled solenoid switch and remote control handset The same type as used on Model aircraft That would save on carrying and using the cable Deako why dont you try the same thing on your magnets B) Quote Link to comment Share on other sites More sharing options...
The Sniper Posted July 30, 2003 Report Share Posted July 30, 2003 Flightline, I tried to extend the cable on my rotor so I could turn it on and off while in the hide. I used speaker cable...about 30 metres of it. The rotor slowed down considerably due to the extra resistance in the cable. Could this be what is taking all the power out of your battery ? Actually I only get about 40 mins on my rotor with one of those batteries you mentioned.......are you expecting too much of the battery ? What sort of time out of these batteries would anyone else expect on a flapper or rotor please ? Quote Link to comment Share on other sites More sharing options...
Rob G Posted July 30, 2003 Report Share Posted July 30, 2003 I use a 12v 7amp batterie on my rota,it will work for 2 1/2 to 3 hours take 2 days to charge.You would need to talk to an electrician,i cant see why you couldn't fit a timer(like those fitted to windscreen wipers on cars)you could have it go every 30seconds or so.

Guest flightline Posted July 30, 2003 Report Share Posted July 30, 2003 Hi Sniper. I get 5 or 6 hrs plus out of this battery with my rotor. I`m pretty sure it`s the extra resistance from the cable that`s causing the problem, though it`s possible it`s the flapper causing a big drain of current, of course. Please keep the ideas coming guys and thanks to those who`ve replied already. B) Quote Link to comment Share on other sites More sharing options...
Cranfield Posted July 30, 2003 Report Share Posted July 30, 2003 I agree that it is the cable thats the problem, not the battery. You mention that your flapper is "home-made", what is the arrangement regarding cable and controls, on the commercially sold ones ? Surely we have enough DIYers on here to solve this one.

Guest flightline Posted July 31, 2003 Report Share Posted July 31, 2003 Thanks for the ideas so far-any others please? Quote Link to comment Share on other sites More sharing options...
kevin15 Posted August 4, 2003 Report Share Posted August 4, 2003 Have the battery in your hide with spade end connectors, have one connected and touch the other connector as when required. i use to do that all the time befor i bought a timer unit which i can run two flappers and two peckers at the same time. with the timer unit no need for a long cable.
