This is Steve Kaluf, Assistant Marketing Manager at Hobbico, showing off the new OS 105 engine that comes in two versions; with either a normal carburetor or a demand regulator system which supplies fuel under pressure to the carburetor for 3D flying. Hobbico is also carrying the complete line of Raptor helicopters, including the new E550S (electric) and 50S for nitro power (with governor). Both of these helicopters come 95% assembled, and are suitable for entry-level pilots all the way up to 3D flying.
