I've recently built a Tiger 60 and a Tiger 2 both of those were ARF's and come with the trike hardware. The box that each one came in had a picture of one set up as trike on one side and on the other side it had a picture of of one set up as a taildragger. I built both of these as tail draggers but did not get the Goldberg conversion kit. You can peice your own hardware together for a good bit less than the kit from Goldberg. And I like a 91 two stroke on the big bird and a 55 two stroke on the smaller one.
