Bought and did a short flight from my home field and back. Took of at MTOW and the 2600 feet runway was just long enough for a safe takeoff. Regarding ground resistance I thought it seemed pretty realistic. However, the Darts do, as someone said earlier, require some time to spool up. The first time I applied way to much power so the aircraft set of a lot faster than I wanted it to. Second time was much smoother, just give the engines a few moments to do their thing. The aircraft does not move at idle thrust, at least not at MTOW, and the brakes can easily hold full power.
System wise it's much better than earlier JF offerings, just about everything is clickable and all switches have sounds, something I really like and earlier products didn't have. The F27 flies well and feels really heavy - just as I imagine the real thing does. She is extremely stable. The landing was the trickiest part, even at flight idle the engines produce a lot of thrust. It was a bit tricky to get it down onto the runway, you need to be slow early on to put her down properly. Ground roll with full braking was about 500 meters which is the same as the manual says.
So far I'm very happy with this thing.
