Product overview
The Scorpion SII-65 & SII-5535 series Stand-Off is a motor mounting accessory for giant-scale electric airplanes. It addresses the installation space associated with firewalls positioned and drilled for longer gas engines. The physical assembly uses four stand-offs with M6 mounting threads, accompanied by adjustment washers, screws and spacers. Its 100mm length can be supplemented with 6mm, 3mm and 1.5mm washers to position the motor within the airplane’s cowl. The specified hardware weight is 260g.
Integration is described around particular motor and gas-engine length references: an SII-5535 with the stand-off matches a DA60cc engine plus a 1-inch standoff, while an SII-6530 combination matches a DA120cc engine plus a 1-inch standoff. The corresponding gas-engine bolt pattern depends on combining the stand-offs with Scorpion Freestyle Cross Mounts. The supplied configuration lists four washers of each thickness, four M6 ×16 hex screws, four M6 ×20mm hex screws and eight M6 spacers alongside the four stand-offs. Weight including packaging is 272g.
