Default T-REX 450SE - Top Speed?

OK -

I'm intrigued - I've searched all around here for the info - but can't find anyone listing top speed of a T-Rex se with a 430L brushless motor. I swear it must go 100 but I'm not certain - anyone have any good ideas? I am banking in a circle near my house and I am crossing about 8 lots in each circle - I can go a full circle in about 10 seconds. Mind you...it's a large area I am flying in.

AlM9SlDEWlNDER: It's hard to say, but I doubt it's hitting anywhere near 100. 40mph feels quite fast, and 60 seems to be like warp 8

I used to have an old Delta Wing .60 w/tuned pipe, and that thing was fast. In level flight, we clocked it one time going 96mph using a hand-held radar gun. It was moving so fast, it was all I could do to control it. One blink, and it would be GONE.

I'm sure they probably exist, but I've never seen any RC heli move anywhere near as fast as that old plane did.

I think I read somewhere recently that some guys running a TREX 450 SE with a medusa and 4S clocked it using GPS going around 65mph in FFF. I'm not sure if this is good or bad for such a setup, but seems very fast to me...

They retreating blade stall at about 85kph/53mph at a headspeed of 2450 RPM... that speed is proportional to headspeed, so at 3000 that would be 104kph/65mph.

And yes, that is scary fast.
