Hi,

Yeah - it is really more so I can get a scale look to the model. The inverted root airfoil will have +3 incidence. I got these figures from http://rauch-airliner.com/Introduction.htm - his beautiful aircraft would have similar weights to my planned one, and similar airfoils etc.

Thanks for all yuor advice so far - I am like a sponge - if you can offer any other ideas i'll happily take them on board!

FYI - the model would hopefully have an all fibreglass fuse (from a mold) and a foam wing, balsa sheeted and glassed. The tricky bit will be to balance all the operating equipment that needs to be in the wing (gear, flap actuators x 3, and slat actuators) against the airfoil thickness! I am hoping to figure it out in Sketch-up in proper scale to try and get it all figured out!

Thanks!
