I say build it and fly it if you have next to nothing in it.  If you crash it...you can salvage the parts (motor, esc, servos, gyro) and put on a new heli of same size.

Really, the kit is the cheapest part of a build.  you start racking up money in electronics...and they should be usable on any 500 class heli.

Just my opinion.  BUT...to counter my own statement...you will have some crashes when you first go to CP helis.  I started out on co-ax (what a waste)...then to FP...and when I went to CP, i still crashed.  Granted, not that much...but out of my 250, 450 and 500...ive crashed them all at least once.  The 450, 3 times!  lol

So, saying that...maybe the best thing would be to sell it like someone else already posted and put that money towards a good clone of a 500...say like the EXI and electronics.  That way you will have the ability to buy ANY part you need, clone or Align for an Align 500 heli.

goodluck!
