hey AK!
although 99.9% of the time the E-Flite products are right on the money, they are experiencing problems with the micro plugs that connect the motors to the board!
i have the mSR and have had the same issues! the remedy for which (you're not going to be too plussed with this one!

) is to unso
lder the female side of the plugs from the circuit board then so
lder the plug pins directly onto the CB, making sure you mark which one goes to which and correct orientation (i.e. mark the upper side of the motor's plug and do them one at a time!!)!!
hope this helps
