Thunderbolt battery holder (standard)

a battery holder for 3dLabPrint 3d printed RC P47 N15 Thunderbolt standard version (does not work with Slic3r version, for Slic3r there is another thing)
This should be very important part because if is battery moving inflight it leads in move Center of gravity of whole plane which is then uncontrollable...
This part gives you the confidence
VERY VERY RECOMMEND
