HQProp Juicy Prop J40 5.1x4x3 Polycarbonate (2CW+2CCW)

HQProp's Juicy Prop J40 is a 5.1-inch tri-blade with a 4-inch pitch, moulded in polycarbonate and sold as a set of four: two clockwise and two counter-clockwise, enough for one quad. It suits 5-inch freestyle and cruising builds that want slightly more disc area than a standard 5-inch prop.

• 3.4 g per prop
• 12.4 mm hub, 6 mm thick, with a 5 mm bore for standard M5 motor shafts
• No adaptor rings needed: fits 5 mm shafts directly
• Polycarbonate blades flex on impact instead of snapping
• Available in grey or blue

At 5.1 inches the J40 runs slightly over the nominal 5-inch size, so check prop-to-prop and prop-to-frame clearance on compact 5-inch frames before fitting. Each set equips one quad; a spare set covers a session of crashes.
