  • Heli top speed in a dive

    I noticed that pirouetting stall turns seem easier and less rushed in Phoenix than in real life, and was trying to figure out why. I think it's because the helis in Phoenix don't pick up speed in a dive as fast as my real helis. It's almost like there's a parachute on the tail. In addition, the terminal velocity in a dive seems much too slow, both visually, and when looking at the speed the simulator says the heli is going. I realize there's a psychological factor because diving straight down in real life is going to be more scary, but it really seems like the helis dive too slow in Phoenix.

    For instance, if I take the Trex 450 up to 300 feet, and then put the pitch at 0 and point the nose straight down, the heli only reaches a terminal velocity of about 50 mph. If I do the same experiment with the Trex 600, it gets up to around 60. It doesn't seem to matter how high I start the dive from, that's its terminal velocity. This is actually slower than the heli's top speed in level forward flight. Does anyone else find this unrealistic?

    Thanks, Adam
