You need to go to the website. They show the Mk11 kit currently avalible If he wants one in this economy I would not dally around and get it now!

Its an excellent airplane but stuffing a modern 46 in it as most do it loose's it character and the purpose to which it was designed.

The very best engine you could get for it is the new OS AX's and specificly either the .25 or the .35 These both have the new carburator which does so much to enhance the enjoyment of an airplane like that. There are lessor (cheaper) altenatives but I'll leave that to others.
