2. The distance on take-off to break ground. Would there be any difference between a standard, say 172A, and the same model converted to tailwheel?
Depending on the condition of the field it would be rather presumptuous to expect you are guaranteed to break ground at all with a trike and not end up with the nose gear buckled up under you, a lot of my TO/landings are into unprepared/wet/soft/muddy strips, I would not have the balls to do that in a trike no matter the STOL performance .
