Thanks for your comments Peter. I'm very pleased to have found a suitable subject for the Enya which I had bought at a bring-and-buy. I saw a couple of pictures of your King Condor in a 2002 Magazine with a 40 FS up front so I purchased the plan. With the model taking shape I felt that the 40 would be too heavy up front, so I switched to an OS25. For a relatively small model ground handling is good, it flys beautifully & does'nt nose over on landing, excellent, Many thanks
