I have been thinking of that engine combination myself.Thanks for the reply.I too am just starting to go gas for the first time on an airplane.Is the only or best place to get those engines is at rcshowcase?Thanks for any help locating me a place to buy one.I am hesitant to put the 160 on it.I think will be plenty to power it but not do any of the 3d,slow verticals and many of the other manuvers I want to do.Thanks Tivey
