I never made flightbows before but we have in Poland in April 2014 first flight tournament. I want make 2 flightbows in 70 lb class - Molly style and turkish hornbow. I just finish 2 bows , but both too light draw weight - about 55 lb at 26 ". I work now on next, stronger bows I hope I can make it on time.
Molly 59 " ntn and 54 lb at 26" - ipe/maple/sinew . 5 mm ipe 5 mm maple. Snaky handle give centershot. On handle white ox horn on tip water Buffalo. 50/50 rate , 2" wide working part on tip only 4 mm. With 25 " 250 grain arrow and 24,5 " draw about 200 fps. It maybe not impressive on flightbow but second bow will be shorter 3-4 inch and stronger , I expect
much more speed.
turkish bow - 55 lb at 27" , 45 NTN , mass only 290 gram before leather cover. Arrow speed similar . Next will be stronger and 3 inch shorter
