Well...Almost all planes are ranged for .049-.074. Dont get one of these! they will fly so slow its pathetic. I would go with a .20 sized plane, the only problem is, no one makes them much anymore and you would have to get one from a specialty hobby shop, theres a guy on here who sales a bunch of old .020 & .010 kits, the name ecapes me at this moment, Ill remember it in a bit. Those run about $38 for a .01-.02 because they are no longer produced kits.
Hope some of that helps.
