Ok guys so I have been tuning my airforce condor and finnaly got it pretty much tuned. The last thing is to put these talon tunes washers behind my top hat. So I am wondering how exactly I should do this. I heard that there should be about the space of a quarters edge between the washers and the top hat. Can anyone confirm? I just don't want to sand down these things too much and have to order more. Thanks lads.
