This is what I think because I just crashed a nexus.

PARTS ARE MORE EXPENSIVE FOR THE NEXUS!

You can find new in package parts for the raptor on most forums, auctions, or whatever from end users for considerable savings! Buy a bunch of parts in bulk and save a bunch of money. 2nd hand parts for the nexus are hard to come by.

I'm not saying that you will be able to find all the parts that you will ever need, but if you like to stock parts like I do, then the Raptor is definitely the choice among all helicopters. Just buy spares when you see a good deal and stay ahead.
