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?

The iFlight XL5 V3 is a fantastic freestyle frame for the price. It features chamfered edges on some very nice quality carbon fiber. My goal for this build was to use high quality components at a relatively low price. Not only that, but I managed to reduce the number of solder points to the bare minimum.
