Very interesting. Funny how alot of these designs all kind of act the same when it comes to ground handling. I`ve been flying my Proctor N-11 for years, and landings (grass ONLY) are still exciting.
I can take off most of my WW1 models from pavement, even do touch and go`s....but landings? Fergit it. Yep, the D-7 is a great flyer, and would certainly be a kit worth considering.
