1/2 a Spectra line size?

[kevin king]

Can someone please tell me the Spectra line size for 1/2a please?

[Steve Helmick]

Somewhere between 10 lb and 20 lb test should work well. IMO, the Power Pro "Slick 8" would be a prime choice.             

I always suggest buying from a legit brick & morter store, even if online purchase. There have been reports of Chinese counterfeit "spectra line" that had zero spectra content...bought from eBay or AMAzon. I tend to buy from www.TackleWarehouse.com, but you should have a fishing supply place in Canada that can get it to you faster, without any of the usual "storage" at Customs. https://www.tackledepot.ca/ or https://thefishinhole.com/  Steve

THANKS STEVE!

Kevin check out Canadian Tire , they carry a selection up to around 40# . Blue shows up ok if the yellow isn’t available. Green is really hard to see .

   Steve is correct in his assessment. But just weigh the airplane and the pull test if still 10Gs. So a 10 ounce airplane is 100 ounces. Divide that by 16 and you get 6.25 pounds pull test.10 pound line should be finem and I agree with Steve on getting the genuine article from the local Bass Pro Shop of Cabela's. They seem to restock fairly frequently but they have ordered yellow for me when I wanted it for free delivery to the store. I'm flying my .061 Doodlebug Brothers airplane on 10 pound line now and I'm up to 47 feet. I can't imagine flying this on that long  of .008" steel lines!! They would be a nightmare to take care of !!!

To keep it simple, this is right from the AMA:

Model wt oz    Engine size     Watts     Rated Spectra lbs

     24                  .09             300            20
     40                  .25             450            40
     64                  .40             600            60
     75                  .75             750            100


I use 20# for 1/2A even though its overkill.

And don't forget a model pull test is pulling on 2 lines, so on the example above each line is only loaded to 3.125 lbs. A safety factor of over 3 for 10# rated Spectra.
