I am looing into building a long-range(ish) r9m 4" with 1407 too.
How much flight time do you get out of your build? Hows the dry weight? How far did you go with it so far?

In terms of dry weight i am not sure don't own a scale:( I am getting around 5-530 just crusing and 430-5 doning light freestyling, I just got the R9 in last three days ago and haven't gotten my smart audio working quite yet so haven't pushed ranges to far.
