Because of my ignorance I have this question..(from another thread but thougth it was interesting) I just thought, it brings up another point, the new(ish) pilot powers...they are speed rated to 169 I think it is...is this a better or not as good rating as the 149 plus rating other manufacturers use? when they say 149+, what speed does that encompass? to 300? to 400? or to 150mph constant speed for 1 hour or 5 days??? anyone know how they rate these and exactly what the numbers mean? maybe this is a question for the vendors at the track.
