| SP Series Features | | Streamline shape, perfect for cowling | | | 2:1 Reduction Gearing | | | Uses Scale Props - 2, 3 & 4-blade | | | Low Maintenance | | | Behind the prop starting facility | | | 2-Year Guarantee | 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 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, our RCV60-SP engine is a perfect option.
