2 BLADE V's MULTI-BLADE PROPS
Although multi blade set up’s look great and allow the blade length to be shortened, they usually provide slightly less thrust when compared to two blade standard props, due to the increased drag from more blades. When a two blade provides less thrust it is because the two blade is not operating at it full potential (It is not within the prop powered band, or the incorrect prop is being used in conjunction with the incorrect reduction ratio or pipe system). They are however smoother running due to the increased blades and should the blade be variable as shown in the picture, then this eliminates the need for different props should different engines be flown. It also makes mending easier as only the damaged blade need replacing. Multi blade simply looks far better.
