The Dr.1 is not the beast in the air everyone says it is. You have to stay aware of 2 things, weight and drag. Although it's only 72 inches, it still weighs 14 pounds. It takes a lot of room to perform and recover from aerobatics. Due to the large amount of frontal area and parasitic drag, when you chop the throttle, it stops RIGHT THEN.

Takeoffs can be interesting and landings can be scary. You need to have a quick right thumb on takeoffs and you have to get air moving across the rudder to steer effectively. To land, you have to maintain about 1/4 throttle and keep the nose level on final. If it looks a whole lot too fast on approach, it's about right (remember the drag). You don't cut the throttle until it's about 1 foot high. DO NOT attempt to flair or make a 3-point landing. Touch on the mains first and let the tail settle. You keep your thumb on the rudder because it WILL swerve. It likes to nose over. Nothing new about this. The full scale ones did, too.

Other than these few minor details, it's a great flying plane.
