[NSRCA-discussion] Brio 10 & high altitude

[Larry]

Hi Jeff,

Check out this thread on RC Groups for several recommendations from guys 
flying at or above 5000

In general - they go up one size in diameter on the prop in order to get 
similar performance to what us low-lander get with the same motor and packs 
:)
