I've had both planes. Still flying the Superstar (well it has been turned over to the kid). The Hobbistar was a great flying plane. I replaced it with a PT-60 with a Magnum 91 four stroke. I think the Hobbistar would be a fantastic second plane with a four stroke on it. I did put a bright orange stripe on the bottom of one wing on the Hobbistar. It made it much easier to keep track of orientation.
