Hey mick

The a4 skyhawk is a nice little plane, i had a .52 2 stroke on it and it flew just fine, untill a mid air strike with another plane i was dog fighting with one afternoon at the rc field,,, i will get another one soon,, as far as the CG, line it up right behind the pilot,,,, just make sure it is a little nose heavy for your first flight, You do not want to fly this plane tail heavy at all, and i mean not even a tiny bit!!!
also go by the book on the control throws and make sure you do not input to much elevator in the turns for your first few flights until you get use to how it flys. this plane has a habit of snaping real hard and going into a uncontrolable spin when you take a turn real tight... just make sure you set the elevator at low rates, its a jittery little rascal, but overall not a bad little plane, and it looks pretty good to...
