The S500 is supplied with 2 x blue and 2 x black arms that are super ridged and have a carbon fibre rod through the center making for the strongest arms we have seen to date in this style of frame. The Blue and black arms make orientation much easier and there is no need for different colored props. The included landing gear has plenty of height making it suitable for GoPro type gimbals or similar. Another feature of the S500 is that when assembled the arms have a slight up sweep, this gives the Quad a dihedral effect which helps make it very stable, especially when descending from altitude. Assembly of this frame is super simple with pre-threaded sleeves for all the frame bolts so no lock nuts are required. It utilizes one size bolts for the entire build which means you only want one size hex for the assembly. Another feature is the locating tabs for the arms which enables you to achieve the perfect alignment when building. The motor mounts are ready to take a selection of motors with mounting hole centers of 16, 19 and 25mm once again making this a very universal frame at a very affordable price.
