The RCV120-SP was designed with the scale modeller in mind. This quality CNC machined engine has a similar power output to conventional poppet valve 4-stroke engines and can be used in scale or general sport models that would normally use a 4-stroke 1.20 or a 2-stroke .70.
However the RCV SP series offers much more. The compact streamlined shape means that cowled installations are that much simpler to arrange, perfect for warbirds, and the 2:1 output gearing allows for larger scale like propellers.
The engine still uses RCV's unique rotary valve system - which has only one extra moving component to a 2-stroke and so is easy to maintain. One more benefit to RCV SP engines is the behind the prop starting facility (now included with the engine, which allows the modeller to stay behind the prop at all times
So if you are looking for a reliable, streamline 4-stroke engine, that is capable of pulling scale size 2, 3 and 4-bladed propellers, the RCV120-SP engine is a perfect option.
