Wout, dear boy, homebuilds are usually streng verboten in this forum, mainly because there are just so many of them. If some deranged Panamanian poppy-muncher collects all the wrecks from his local flying school and assembles the Rodriguez Flyer, there's no way we get to know about it, or even care.
One-offs are OK if they are somehow unusual, but Piper/Cessna clones just don't cut the mustard.
Having said that, this looks like it has some Auster/Taylorcraft in it, other than that, haven't a clue.
Sorry if I seem intemperate - the weather has been oppressive and humid here and I feel quite homicidal.......
