dude.. i am not saying my car is fast enough.. but most of the energy by the helicoptor's engine is used to create LIFT and keep the helicoptor from spinning (the tail propeller).. most helicoptors do NOT have a very fast land speed. they were not designed to go far or fast.. their design is in their flexibility, the ability to hover, or fly straight up or down)

in chases they are used to SPOT the offender, not follow them.
