Slight modification.

This is a work in progress remix of http://www.thingiverse.com/thing:241977. The new plates are meant to utilize these arms: http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313.TR1.TRC0.A0.H0.TRS0&_nkw=HMFS550&ghostText=&_sacat=0 The plates were elongated by 20mm in both front and back, as well as left and right directions. Meanwhile, the arms are marginally longer than the standard DJI arms. There exist two versions of the lower plate: one with tall risers to maintain stock spacing between plates, while another is shorter for aesthetic appeal. Nine-inch props are shown without motors, while eight-inch props can be easily swapped in place. Other, significantly longer arms are available, serving as a direct replacement for original design elements and allowing bigger propeller sizes if necessary: http://www.rctimer.com/product-845.html Despite limited modeling skills, the aircraft successfully takes to the skies. Work is ongoing to refine the taller bottom plate and perfect its design.
