I really, really, like this teeny-tiny kit. No modifications to the model. I did make a small flat decal to simulate the cockpit. If you look very closely at the canopy, you can see it adds a little depth to the model,

As you can see, the model with landing gear is tail heavy. The aircraft looks like it is in a takeoff roll. If you don't want this appearance, a small, six-sided dice under the rear fuselage takes care of this issue and isn't visible to the casual observer.
