I am new to the brushless (airplanes in general) and I can't figure it out. I have the prop adapter that come with the Park 400 bl but can't figure out how it stays on the motor shaft. I see how it is suppose to clamp down as you slide the collar up but it still doesn't grip it tight. So....what am I doing wrong??? This is stressing me out more than building the whole dang plane!
