A pair of Arbalests. This is the latest design by David McFarlane and continues the medieval weapons naming theme started by the Slingshot through Trebuchet and Ballista. These are virtually identical except for the obvious appendages (wing fences, sfg's and large cannalisor) on mine!. This is my first attempt at a fully moulded fuse and the learning curve was steep but fun. The plug, mould and test flights are described in the Blog on this site www.nswpattern.org.au under Ballista Evo II until we renamed it. A few details:- length1945mm, span 1730mm, wing area 61.4 dm(950 sq ins). Both use JR digital servos but David is using high voltage with no regulator. Mine weighs 4640 gms with an 1190 gm F3A Unlimited 4900 pack while David's is 4915 gms with a 1200 gm Thunder Power 5000 pack. The main reason for the difference is that David's wings, stab and rudder are glassed ( 0.6oz) and painted while mine are honey combed and monocoted. As a comparison my wings, without the wing fences (these add 17 gms per wing) are 320 gms ea ready to fly, while David's are 410 gms. The main contributors are honey combing saved 38 gms per wing on mine and the glass added 60 gms + paint 47 gms on Davids compaired to 47 gms of film on mine. We didn't have quite enough wing dihedral (0.9 deg) and mine needed 12% rudder to aileron mix to fix the adverse roll. After changing battery position then restoring it because I am using also using Zippy compact 5800 packs weighing 1300 gms I made a couple of new cannalisors of increasing size and dihedral.The rudder to aileron mix on mine is down to 1% to correct proverse on left rudder and 3% to correct adverse roll on right rudder. The next build will have more dihedral so I'm sure the large cannaliser won't be necessary- any way I am happy with the outcome and beauty is in the eye of the beholder!! We are both happy with the way they are flying and continue to trim and play - as you would understand. Cheers Bill
