matt fieldcrafter-uk Posted May 17, 2013 Report Share Posted May 17, 2013 Hello fellas I'm one of those people that looks at things and wants to improve them ! Iv got a magnet and its effective as they are . But it's two slow on the slow setting and to fast on fast . The result is it works better at attracting birds on fast setting but kills the battery fast . Iv tried a speed controller but its not that effective really . My new plan is to make longer 2 piece arms for the magnet . My theory is using physics that a smaller movement at the motor end will generate a larger movement at the decoy end . There for running my machine slower hopefully extending battery life . Also I do worry that the tight circle the magnet generates some times puts birds off . Has anyone tried this and saved me the bother ? I'm able to machine/ fabricate the arms no problem at all and the materials are negligible in terms of cost . What's your thoughts. ?

Billy. Posted May 17, 2013 Report Share Posted May 17, 2013 Remember that your battery will drain much faster if you extend the arms and remain at a lower speed. I'd always advise a car battery. A nightmare to carry, but worth it for the longevity. I've seen some magnets spinning at silly speeds and they pull them in no problem.

TIGHTCHOKE Posted May 17, 2013 Report Share Posted May 17, 2013 I have longer arms on my rotary, mainly due to going through the process that you seem to be embarking upon! I changed over to Hypa-Flap decoys in order to make the weight at the end of the arm as low as possible. This way the motor does less work and the battery lasts longer. If you were to extend the arms when using dead birds on the end I think you would shorten the battery life massively due to the increased momentum required to get it up to speed and keep it there. Good luck. T.C. Quote Link to comment Share on other sites More sharing options...
superspark Posted May 17, 2013 Report Share Posted May 17, 2013 Extending the arms will no doubt increase the radius of the pattern but will also increase battery drain due to the extra force needed to propel it around. In reality there are only two real options which would be to use a bigger battery for extended life or don't use dead birds but artificial ones. Have you seen the new decoys from A1 decoys ? they are super light and have flapping wing movement. Take a look at the video on their web page, they look very real so I bought a pair to try out. Think they cost £39 mate. Quote Link to comment Share on other sites More sharing options...
Greenhunter Posted May 17, 2013 Report Share Posted May 17, 2013 In an effort to save me having to get out the hide to stop the rotary now and then, to make it intermittent so to speak, I extended the cable about 20 meters. This had the side effect of slowing the rotation down as well so that could work for you. Not being an expert where electrics are concerned it might possibly have been the cable I used had too much resistence though so that could be another way. Just a thought!

The Essex Hunter Posted May 17, 2013 Report Share Posted May 17, 2013 I have 2 home made rotary’s, the arms are interchangeable but one pair is slightly longer. The material I used is a type of spring steel which holds a pair of adult pigeons and still bounces very well. I can set one arm above the other just with a bit of a bend; they held up last week even in a gale. The arms from Pine wood machines give a similar affect because they are made of a similar material. It is the white wing bars that show up, so the more movement the better… TEH Quote Link to comment Share on other sites More sharing options...
matt fieldcrafter-uk Posted May 17, 2013 Author Report Share Posted May 17, 2013 Thanks gents . The a1 decoy looks good a very similar thing to Hypa flapper . Has anyone found the longer arms make for a more realistic look or could you say they are more effective ? All the best , matt Quote Link to comment Share on other sites More sharing options...
Goss hawker Posted May 19, 2013 Report Share Posted May 19, 2013 Got the ones from a1 not very good carnt keep the wings attached to the bird not very good quality at all Quote Link to comment Share on other sites More sharing options...
matt fieldcrafter-uk Posted May 19, 2013 Author Report Share Posted May 19, 2013 That's a shame !! Have you contacted them about it ? The Hypa and a1 winged decoys seem to work but are more than basic for the money . I'm sure someone will soon take what they have done and better it !

This is correct to a point, in effect your adding resistance ( a static speed control) Why doesn't your speed controller work? I'd just get that sorted then no issue...

superspark Posted May 22, 2013 Report Share Posted May 22, 2013 Your rotary decoy machine will go much slower if you extent the cable to far due to volts drop, this in turn will drain the battery faster. As the volts drop of the currant will rise. I tried out my new pigeon decoys I bought from A1 decoys last week end. Found them to work well but as soon as the wind got up they didn't fare to well so had to turn it off, bit of a shame. Quote Link to comment Share on other sites More sharing options...
TDRsniper Posted May 23, 2013 Report Share Posted May 23, 2013 I've also extended my magnet cable, I used an old extension cable drum to fit it in so I can be wound up and stored easily. I don't see too much difference in speed and battery drain isn't a problem cause I got a 17Ah Yuasa battery which will easily cope with two straight days shooting, although I'm lucky in that I can drive to any of my permissions due to a wide headland so I don't have to carry it!!!

I used speaker cable and I have the same battery. It didn't seem to drain the battery too much but it was very much slower.I have since compromised and shortened it again but its still much longer and the birds spin at a reasonable speed.
