RE: waco ymf
Procter Enterprises sells a Peter Barth designed Waco YMF5 in 25% They used to sell Barth's 33% kit as well. AMR has 33% and 40% Both are Lazar cut kits. Very easy to build . They are not as scale as Barth's kits are but very nice kits. If you want to build and have a model that is very very scale do the Barth Kit in 25%. Big but not GIANT as are either of the 33% kits are. I built the bigger Barth kit and it fly so well. Lot of work to build but I like building better than flying anyhow. I think GreatPlanes has a ARF of the YMF5 out now. Not sure of the size but it is smaller than 25% I think. It looks O.K. for and ARF but if you want any ARF then don't expect it to be very scale. None are. They just kinda look like the full scale planes. Remember ARF's are cheap to construct, quick to assemble. There designed for those who don't want to build. Instant gratification and no skills involved to assemble one ( you don't build an ARF) but they do fly O.K. they really do.
