or dont get caught up in the overpriced radios - the New flysky noble nb4, dont count it out, i went from the m12s(which i dropped) then borrowed a 4px which felt nowhere near as fast/reponsive. Then probably a waste of money but tried the flysky... WOW the quality of this radio is incredible, the feeling of control is sanwa like, so many people have now caught on and are changing over, the micro rec are very cheap too.
But still, if you want the best expensive radios, the m17/m12s/mt44 will deliver everything you need. futaba is not special like it used to be.
