Thanks very much guys! For the foreseeable future I have a few more single-engine J-birds on the menu and I also hope to finish my Corsair this year.
As for the Tojo, the Maru Mechanic drawings were indeed the best I could find, though while working on my model I deviated from them a few times were I believed necessary. Nothing too major luckily. The Ki-27 was more challenging. Again I started off with the Maru Mechanic drawings, but they had a serious flaw with the forward fuselage (which is straight, not curved, in top view). While just about all other drawings did not have this curvature error, they have the forward fuselage too narrow which in turn distorts the entire cowling (too much bulding/pinching effect). The Maru drawings also showed the droptanks incorrectly (they’re aligned vertically, not perpendicular to the dihedral as per drawings), amongst other things. I got there in the end though.
Btw, here are the RC Tojo videos I am referring to: http://www.youtube.com/user/tojoflier
