A bigger plane would use a bigger prop which would use a lower kv motor. Like on a C pack for larger planes the recommended is around 1000kv with a 10x4.5 prop. For small F pack planes 2200 kv is recommended with a 6x4 prop.
That motor with a 9x4.5 prop will work very well on the cub. Like @Timmy said, it'll have a little more power than a normal c pack but that's not a bad thing.
