RE: balsa kit?
Maybe a [link=http://www.oz********.com/2007/01/raving-about-rv4.html]StevensAero RV4[/link]. Is a nice little low wing scale parkflyer - will fly well on 70watts (is built so it can use an EPS350 if you are on a budget), but I have mine kicking about on a cheap towerpro brushless - about 130watts and she is a lot of fun. Mildly aerobatic (She can knife edge but it takes a lot of control coordination).
I love mine - is a kit build from laser cut balsa.
Cheers,
Oz.
