It's OK guys, I've checked online and found out that dynam's Bf-110 which has 150cm WS has CG 80 - 85mm from the leading edge at the wing root. My bf's wingspan is 110cm (I made it smaller to fit 1804 motors with 5' props) so I divided 110 by 150 and multiplied the result by 80, which gave me rougly 60mm. Luckily I made it before dusk and with CG set she flew like a dream, but it appears that the throw on elevator is through the roof because she turns in place, literally. The other problem came with downsizing - I can barely fit Rx inside the fuse box
I'll just run her on smaller rx I guess. That's how she looks now, all made with 3mm depron and 5mm floor underlay. Weighs roughly 300g without battery, for a 1m+ WS plane it's feather weight
It may not look like much, so here's a pic of Fw-190 I made lately to show how I hope she's going to look like. I'll post here again once I'm done.
Good design Whit, chapeau bas!
