My Bob-Cat was powered by a RAM 500, till the turbine blows up! Turbine-wheel has broken.
Then I install a Behotec JB 165 with 174 N, rated down to 100 K.
Need full power only for TO, in the air the throttle sets at max. middle position, which result in power of approx. 35% !
In this config the jet flies great and very quiet.
