10x6 or 10x7???? NOoo !! you don´t want a fragile plane to fly that fast; try 12x4 apc or singer; or the beloved 12.25x3.75 APC Lot`s of thrust, less speed, more air over the suefaces, more gyroscopic effect, better 3d, best with a "tower muffler"
best regards,
Tower muffler & apc 12x4 will bring your .46 into an entirely different dimension. [sm=thumbup.gif] Don't worry, you will still have more speed than you need.
