I was at the field last week and one of our club members had the first G. Nobler (Ultra Hobby Products) that I have seen. He was flying and trimming. I have never seen a T-Rex fly yet so I can't speak to that, but this little G. Nobler performs like a pro. Stable, Good corner, Good glide, beautiful landings and it had an excellent quick/tight corner. This one was powered by an AeroTiger 36 and it pulled it around just fine. Mostly running in a 4 stroke mode on the level and leaning out in the vertical maneuvers. It was covered with all monocoat. The plane impressed me. A good pilot on the handle and it will be really hard to beat.
