RE: Balsa USA Citabria Pro
The Citabria Pro will only fly like a Cub if you power it like a Cub. The recommended engine sizes that come from BUSA are clearly all to small for a plane with an 80" span and weight of around 11 lbs. The kit has been around for quite a few years and the recommended engines were all appropriate when it was first put on the market. With todays light, powerful engines being available, why use an engine that is obviously to small for a plane of this size if you want to fly aerobatics with it. If you take the size and weight into consideration for an aerobatic plane it's pretty clear that it will take a 1.50 four stroke or a 1.20 2 stroke, or more to fly it right. And don't forget, this is not a Cap or an Extra, it's a scale aerobat of a plane from an earlier era and it flies like one, not super precise but very capable nonetheless.
From what I have seen the majority of people that have built and flown this model and are displeased by it have all underpowered it. That's why they always say it flies like a cub...
