Not blistering but fast enough for me..... Iwould guess 180 or so flat and level. A friend radared my passes and it wasn't straight-on about 15-20 degree angle and the passes were about 3/4 throttle at 140. If you want speed, go with a Rhino or 160 - you'll just pay for it in flight time. Timer set for 7 min now. Couldn't be happier!
