I would personally get the ARF. Not so much for the build but because you don't need the extra TX/RX that come with most RTF stuff. Usually the TX/RX packaged with RTF models is pretty much basic stuff with no frills. BTW - The DX6i is a great first computer type radio. Ihave one and fly all my models with it. If you get it soon, you can take advantage of the current promotion that Spektrum offers. I got 3 receivers with mine as the promotion is that you get two AR6115e parkflyer receivers for free. I got mine for $190.00 out the door.
