Latest update: Now running the APC 15x4 prop', and what a difference! Much better pull and acceleration. Hovering is easier too with sharper acceleration on pull out. Little vibration compared to the 14x6 Master I was using previously. It's also a terrific airbrake in a dive with the engine at, or close to, idle. All good news with the APC it seems, until you factor in the price - £14.25!
