Bipes seem to run more in general. Your looking at 2 wings. If you figure the time it takes you to build a plane wings/fuse then turn around an build another wing then cover it etc etc You can start to see where the etc dollars come from. Look at it this way your giving some chinese guy a few more hours work.
Im anxious to see how the bipe will 3D. Bipes are notoriously bad 3Ders, or should I say have some bad habits. If it 3Ds well it should be a real winner!
If the bipe has 1300 sq of wing like TT said it really is a big plane too. Almost a .60 size plane that will give good performance on a stout .46
Cmon Dion you cant pick up a few of them for us to try?[sm=confused.gif]
