Not really, it's a pretty easy one to put together. I modded both of mine to have dual elevator servos in the back after flying with the stock pull pull on the elevator for a while. Flew much better, with greater travels and easier setup than the stock setup. Plus, it makes it easier to get the CG back. Sicneyours is the ARC, it'd be a lot easier to build a couple trays back there than it was for me to cut covering and recover.
