Throttle springs are a life saver they are installed to pull the throttle to idle if the linkage pops off also some airtronic servos go to a neutral setting during batt. power lose and can free wheel thus the spring can pull the servo linkage and throttle closed with out any problem. The best thing to do is enclose all wires and tie them up. enclose them were they can not come loose and if you are running "AA" batteries then wrap a rubber band around them to hold them in the batt. case so they cannot fallout or bounce out. This is JMO. So take it how you well.
