sorry, but, WHAT THE HECK DO YOU DO WITH 3 #4s????

I guess fly em but...
Well, if you go CP the blade CP is a good choice, it's challenging, and less stable then a TRex, (similar to a #4 if I remember correctly) but flies great and is decently simple, as well as cheap as heck to replace parts on! (besides the fact that most hobby stores carry them)
