I just finished my Hangar 9 3.1M Sukhoi and I would challenge anyone to find a better bult and engineered balsa and covering ARF at any cost. I would put it up against 90% of the kit built planes out there flying. All top notch harware and everything fit perfectly. I have owned many. many Hangar 9 ARFs over the years and have always found the quality to be second to none.
