I fly both the falke and the RF3 regularly
RF3 has fantastic handling, i really want to do aerobatics in her but alas only the rf4 is aerobatic...RF3 is faster, better looking, rectracable main gear, simple engine, sips fuel. Still can be tricky to taxi in a x-wind, but are'nt all tail draggers?? it still has a rubbish climb rate (i am on the lardy side though!) and it is single seat. RF3 doest not have an electric starter so starting can be a pain but big thumbs up for the RF3
Falke is a dirt cheap 2 seater, rubbish climb rate, heavy ailerons, but fun, (you can loop them!) A great tool for teaching glider pilots in the winter. I enjoy them a lot, dispite all their down points because I think they are a bit of a laugh! They are slow though.....
If you want company get a falke. Both are cheap to operate.
