From the MVVS Canada website: "This combo spins a Menz "S" 18x8 propeller at 8400 rpm, producing approximately 17 pounds of static thrust! On a 10-14 pound aerobatic airplane,
From [link=http://www.rcfaq.com/rpmstats/rpmbymfr2.htm##Saito]Model airplane engine performance database[/link] Saito 1.80can turn 17x8 from 8700 to 9300 (at 30% nitro). and everybody flying saito with H9Edge at 11+ lb claims full 3D performance. From the [link=http://home.flash.net/~jecramer/mvvs160.htm]real guy and real plane[/link] (not test stand run) MVVS turned 17x8 at 7900 rpm, so it is significant less power than Saito - is is enought for 3D on 11lb?
I don't see how I can make this Edge less than 11 lb (fueled): 7lb (airframe + hardware) + 1lb (radio + battery) + 3lb (engine + fuel).
