well ,ill be the first to admit,,after around the time you get used to a new plane
,im allways looking for more power,,and any one should know nothing replaces displacement and where i live above 3k asl.if a 50 cc is recommended a 60 ,,would do better,,,one great advantage ,theese days,,is lighter components and stronger servos and batteries,,allowing us to fly bigger planes with smaller motors,ive got a current 30 pct.yak that weighs 7 pounds less than the same size vintage 1989 ,,model,,of the same scale,,so in retrospect,,its all good.
