4* 40 all the way. Ramcharger had it right. 40 size has all the zip without the lethargic 'which way did he go, george' that most 60 size planes have. I believe the 60 size any plane is pushing the envelope of what balsa and lite ply can do in relevance to speed and handling characteristics. 40 size: not too big and not a pindot in the sky, either.
