I have a Modeltech P47 60 size. Great flying plane that handles wind well and is as easy to fly as a trainer. The one thing I had to replace was the nylon block piece that bolts in for the tail wheel. It looks old and brittle and shatters to little pieces when very little pressure is applied to the tail wheel. I bought a new piece which looked as old as the first one and it broke the first time the tail wheel moved! I had enough and replaced the tail wheel with a Sullivan assembly with no problems since. I also had to add lots of support blocks for the large cowl to keep it on solid.
