Mike.. A 120 will fly it fine and dandy, just a longer take off roll..... I have flown this Jet legend F 16 with everything from a 120 to a jetcat 200 with 52 lbs thrust and they all fly great just a superb vertical with a 200 on tap !!! Just remember to programme your transmitter to switch to flaps and tailerons for take off and landing,, its an easy programme to put on a single switch..they take off and land much better that way,, Malcolm Kay
