I've been around several Super Sportsters and I am very aware of how they fly.
A friend was given the Great Planes EP Sportster for his birthday 2 yrs ago

Needless to say it was an experienced person's poor excuse for a plane as it came from Great Planes.
He changed it to a more powerful motor system and it is as nice as any Super Sportster I've ever seen. He has a couple glow Sportsters also and has been very pleased with his electric Super Sportster. In fact this past summer it was his plane of choice.
