The sig LT-40 has got to be considered as one of the front runners.The only problem I had with that plane a few years ago was to get it back on the ground and make it stop flying.It will float forever on final if your airspeed is only a little bit to high.It is a very complete kit,and as I remeber,all you need to complete it is covering,an engine,glue and a radio.It's a pleasure to build.Only my two cents worth.
