[NSRCA-discussion] Brio 10 & high altitude

[Jeff Hill]

I'm getting ready to buy the motor, speed control and props for the  
Brio 10. Any ideas out there about which prop and motor combination  
will work best from 5000 to 7000 ft?

So far, I've reasoned that the motor will have the same power. So, in  
the less-dense air where I fly the rpms should go up or the motor  
should unload. However, it takes the same thrust to pull the Brio  
through its maneuvers unless airframe and lift drag decrease. That's  
as far as I've gotten.

Ideas please, thanks
