hi, this L-39 is a blast to fly, and handles very well. put a lot of time in 2 it, did lots of tweak and adjustments. #ch8 3 way switch all the way down max smoke, white and orange and it macks a sweet blend together, with switch in the middle little less smoke, all the way towards you turns smoke off. #ch5 dual rates and very strong breaks for landing with the dual rate switch towards you engages breaks and is all so low rate, i engages breaks before touchdown. #ch7 is retract. #ch 6 is flaps keep knob all the way counterclockwise. also for fun with little practice it can hover as soon as you take off, soon as it gos start up back of thrust, then ad some. i know it is not a 3D plane it is just fun to try to hover. but the most fun is flying it.{ this L-39 speed is 350+MPH +. you mite want to use your binoculars until you get use to the speed. the smoke colors looks sweet in high altitudes. hope you enjoy it have a nice day. [ THE SKI IS ARE LIMITS}
