especially terms automated flight systems Therefore models use no autosurfaces Hardware Until about year ago models didnt use pressure fuel systems primary reason Cox red plastic tankmounts However choose use pressure now Cox tankmounts offer advantage breakaway type engine mount Under crash circumstances tankmounts engine bearers will shear off saving front end fuselage serious damage also enable engine switching great ease just remove four screws change entire engine/mount/tank assembly However because doubts about continued availability Cox tankmounts conventionally inclined plans
