<font face="Arial, Helvetica, sans-serif" size="3">CCPM = collective cyclic pitch mixing. eCCPM = electronic collective cyclic pitch mixing. All collective pitch helis have either mechanical or electronic mixing. Unfortunately a lot of guys use the terms CCPM and eCCPM interchangeably when what they are really talking about is electronic mixing. It would be less confusing if everyone would use the term CCPM to describe only mechanical mixing.</font>
