Glad to see you are getting a Funtana... I finally ordered one the other day after looking at it for a LONG time- I will be putting a Supertigre G-90 2 cy. in mine.... CG may get tricky but that airplane needs gobs of power to fly properly-
If you ever want a quick drop-in power boost over the 46FX, the Irvine-53 and Webra-50GT are superior engines and run on 5%
Take care,
