I hate the bigs ones, I mean, the idea is grand when it is first conceived...but you can't wait to get started on that 7.5" dia whatever, and half way through your begging for it too end...the sanding, the glueing the sanding sanding sanding more glueing and still more sanding...the money, the painting, the designing.
...but the motors that go in the 7.5 inchers, will also go in the 5.5 inchers...half the sanding, and twice the altitude from the same HPR motor choice.
I think it would be safe to say that I am partial to HPR, but I love to fly mpr as well (right now mpr is still an affordable AP fix)
I declined to vote as there could have been more catagories to the poll...Mid & High power, water power, stomp power
actually I voted HPR...
