the rush and capiche are far better for pattern and freestyle aeros than the funtana- they both have the required side area for really good Knife Edge.
However whatever you choose out of these three will probably teach you a lot

If you want info on the Capiche 50 take a look at www.flycapiche.co.uk
It way lighter than the funtana. The engine you'd be looking at would be a super tigre 50 or something like that.
