How fast do electric helis like say one of those T-rex, or Eco 8 go? What about nitro ones, like the raptors?

I have a Logo 10 on 4S and I stuck a GPS datalogger on it once. It showed about around 40 mph on cruising and about 60 mph on a 10° to 15° dive.

wow, I never thought they'd go that fast.

there's a guy in the Hurricane 550 forums at another site that used the pitot tube on his eagletree... it showed him hitting 130kmh that's about 78mph... bottom line... helis can go fast... a lot faster than you'd think and can get away from you real quick if you don't pay attention to them...

do a google on the ircha annual fun fly, they do a drag contest each year. I think a guy with a dual motor set up on a trex 450se won last year.
