We have been building up our range of cleavers for more than 20 years, and these are now very popular for electric and i/c racing with surface drives. Some customers swear by them for submerged drive as well, but we won't argue! These are supplied in diameters from 30mm to 115mm, many are available handed. They feature the classic, surface prop 'wedge' cross-section with accelerated pitch and cupped trailing edges. The degree of rake (back slope of the blades) varies according to pitch; some of these props have very high pitch ratios, so high rake is needed to control lift. Even so, handling with the higher pitched cleavers is trickier than with 'milder' props.
The typical thread types for these props are 3/16" and 1/4" Dog drive. You can specify another thread type if you know exactly what you need.
Needless to say, our price includes the prop being balanced and finished. The photo shows a small selection in stainless and bronze. The reference numbers for this range are: Diameter in mm followed by Pitch to Dia. ratio. Eg. prop ref 6518 has a dia of 65mm and a pitch of 117mm (65 x 1.8).
