RE: Goldberg Tiger
Add my vote FOR the Tiger2 ARF.
I got one about a month ago. I figured to use it for an engine break-in mule and really didn't expect it to be anything more than just a flyer. Turns out that it's a flyer for sure. I fly it more often now than any of my other airplanes. She's a sweetheart.
The maiden flight awed me. The first landing was amazing. I set her up on final and just clicked back the throttle a click at a time until she touched down. I wound up almost running out of fuel on that first flight because I'd started doing touch and goes and lost track of time.
Excellent flyer. But if you do use her for a trainer, make sure the student understands that she won't level the wings out like a trainer does.
About the only weakness mine shows is knife edge needs full throttle to hold altitude. Not much fuselage side area.
