RE: 4*60 or Tiger 60 ?
I own a 4*60 and have flown the tiger and they are both excellent flyer's, well built ARF's and both are easy to assemble. The big difference is one is a Tail dragger ver's a Trike. I Personal like Tail dragger's and at our old (rough) field a dragger was easer to deal with.
Since both are so similar in flight and quality pick the one you visually like the best.
