SP-56 Series

The SP-56 TS ROS is the newest, forged from using the proven SP-28 parts. The engine is equipped in the standard configuration with 1 sparkplug per cylinder due to the compact size. The dual cylinder boxer style offers a low vibration power dense two stroke for the “below 77 lbs” or “up to 35 kg”. The engine is used by customers in small helicopter config UAS as well as fixed wing platforms.

The cylinder is casted aluminum, and the crankcase is CNC machined to be able to adjust to customer specific requirements or mounting plate.
