APC's Giant Scale Formula props are built for the larger end of the hobby — the 22x10 suits petrol engines in the 20cc to 35cc range and larger glow engines, on aerobatic and scale airframes where a 22in disc is the right fit. Injection moulded from glass-filled composite, so blade profile and balance are consistent between props, which matters more at this diameter where a mismatched replacement shows up as vibration.

At 10in of pitch on a 22in blade, this is a moderate-pitch prop for its size — it favours thrust and vertical performance over top speed, which suits 3D and aerobatic flying more than a fast scale pass. Check your engine manufacturer's recommended prop range before fitting, as engine makers usually specify a narrow band for a given displacement.
