If you want to bring it to the next level,I think your headed in the right direction.Tarvin is a great guy,I built his Monocoupe 110 spc. 1/3 scale.Hostetler has some great scale planes too.I'm assuming you want to get into gas engines,you can pick up a good used G38 for less than 200 bucks,if you hunt around on ebay.You will find that scratch building will require some imagination because most plans are not perfect.jeffo
