Learned on a msr now i have a pretty good handle on the mcpx would a blade 450 be a good next choice? Love the bind and fly stuff. Or would there be a better choice. looking for advice from some of you pro's. Thanks

No I would go to a belt cp or a belt cpx.I had a blade 400 after I went through all the coaxial helis and had a real problem controlling it so I sold it and bought a e sky belt cp v2 and wolla I could actually hover a 3d heli and actually  learned in a very short time to fly circutes with it Imean probably 2 hours.I would recomend it to anyone.Although it is not a bind and fly to work with a dx6i radio unless you change the reciever it come with a very good(for beginers) 2.4 gig radio for around 180.00.But remember it says rtf out of the box but that is a bunch of bs.Go on  youtube and there are some pretty good people there to help you set it up to fly right it takes about 1.5 hours and it is worth it.MY 2 C.
