I'd vote for the Flasher 450SE. Excellent all metal heli for $135 shipped. Pics below.

There is also the Flasher 450PE which has G-10 frames, metal swash, metal washout base, metal center hub, all metal frame supports using tubes thru the plastic, and utilizes SE V2 thrust bearings in the plastic main blade grips. Excellent heli for $60 shipped.

I've bought both and really like them. I've compared the HK450 and Flasher 450 PE in personand the HK450 is not in the same class as the Flasher PE at all. Only thing I would probably upgrade on the Flasher PE is the washout base which is an $8 upgrade to the new trex 450 pro. The latest flasher pe washouts bases are a little sloppy on align main shafts.<br type="_moz" />
