About 50 flights flown with Angel & YS63. This is awesome! It weighs 2,9kg with an empty tank, there is enough power with 30% nitro. With 20% it was quite lasy. Now it's nice. With 13*6 sport prop speed is very good but it can also torqueroll and do some other 3d maneuvers like rolling harrier/loop, if CG is back enough. It rises slowly from hover, but it's sufficient. Notice that 6" pitch is quite much for hover. For F3A it seems to be very nice. YS' sound is very very cool, better than an electric engine IMO
