Hi all,
maybe I'm a bit over cautious as the Sea Fury will be my first warbird after a trainer. I'm still not sure what the correct CG of this warbird would be and here is why.
The manual clearly says the CG should be 8cm from the wing root. I talked to some pilots about this and their first impression was the 8cm look a bit to close to the root. Anyway, getting there seems absolutely impossible with the recommended setup. In my case I have a 4s 4000mah SLS Lipo that has pretty much the same size as the recommended Admiral and it' s even a little heavier. I also put the ESC as far as possible towards the nose and my CG is somewhere at 11-12 cm. I red the forums and reviews carefully and many people seem to have the same issue and putting quite a lot of lead in the nose to get to the CG as described in the manual. That in general wouldn't be a problem but I also read from a lot of people the Sea Fury tends to tip over when landing.
I watched the offical MotionRC video on youtube and came across the comment screenshoted below. Here James states he doesn't use any additional weight but also that he hits the CG at 8cm. I can't imagine this is somehow possible unless the the geometry of the fuselage was changed to put the battery even further which i doubt happend. Assuming James is right and he didn't add any weight how should it be possible to hit the correct CG ? Assuming he flew without weight and the CG was further away from the root I have to say it flew very nice and also no sign of the plane tends to tip over.
Of course before my maiden I wanna be as good prepared as possible. I neither wanna have a plane that easily tips over and might destroy my prop nor a plane that is tail heavy which easily could end in a total loss. Any guidance is much appreciated.
best regards, Sam
