Don't buy a Vmar kit. The Hanger 9 one is ok but everything I've looked at points to the Great Planes one being the best. If you search the forum there's all kinds of info about it. I was all set to buy one, but now I'm looking at the new Phoenix Models Decathlon. THe extra 30$ or 40$ is well worth getting the Great Planes Arf. Don't be enticed by those cheaper off brand arfs like the ones on ebay. In fact most of those use photos of the Great Planes model. The GP is the best one out.
