I have a blade cp pro with a brushless main motor and radio upgrade. and have recently thought i should try to autorotate with my blade cp and set up the thr. hold feature on my radio. i dont know if my blade cp is capable of doing an autorotation because of it not having a vp tail rotor and if the rotor head will slowto quickly because of the main geardirectly connected to themotor. I took my copteroutside and got it about ten or so feet in the air and cut the throttle andit did do a fairly nice autorotation but now i would like to try down at myflying field while in fowred flight and much higher up. and wanted to ask before i find out the hard way ifit works or not. please give me some advice.

You will have no tail rotor to keep the tail from spinning out of control. I do not believe the vertical stab is large enough to weather vane either.
