APC B11x8E Thin Electric Propeller (Black)

The APC B11x8E is an 11 × 8 in two-blade Thin Electric propeller in black fibreglass composite, made in the USA for electric-powered RC aircraft. Pick the standard-rotation version (B11x8E) for a conventional tractor setup, or the reverse-rotation pusher version (B11x8EP) for pusher layouts and the opposite-turning side of a twin. Each order is one propeller.

Key features

• Thin Electric profile designed for electric motors
• Same fibreglass composite as APC's grey propellers, moulded in black
• Pusher version is built for reverse (left-hand) rotation, so it gives forward thrust on a motor spinning the opposite way to a standard prop
• Hub accepts APC LPAR06E adapter rings to centre the prop on your motor shaft

Confirm your motor's spin direction before choosing a rotation, and check your motor maker's prop chart to be sure it can swing an 11 × 8 prop within its current rating. Balance the prop before its first flight to keep vibration down.
