I forgot I had built this little thing and hadn't posted it, so here it is. Much preferred over the 65mm, both for the greater authority and 3s as opposed to 2s. Flies great outdoors and even in the wind, though you'll wonder why you pull so many amps in kite weather. 1404 4600kv 3s on Gemfan biblades has been great, range is excellent with the full-size Immortal-T and video is crystal clear all the way out with the TrueRC Singularity even on 25mw. Flight times from 5-8 minutes depending on, well, high winds. It accelerates and handles excellently.
