I have just found this old thread about the Inception (also sold as the Alpha 1000 - same boat different stickers) and thought I would mention that I have been running mine for about 3 years+ fairly regularly, and I am still using the same motor and ESC that came with the boat.
Its performance is impressive for an ARTR model and it always attract's favourable comments from anyone that sees it in action (not the scale guys of course!) and I only run it when the club lake is empty as it is too fast to run in such a confined space with traffic.
Running the model on a pair of two cell packs ( x2 5600mah 65C) and the larger of the two props gives a really good performance with a 7 - 8 minute run time and is more than fast enough for running on a small lake like the one at Southport - and gives no time for any slight lapse in concentration.
One such lapse (I saw something move in the corner of my eye and it distracted me for a fraction of a second as I was making a flat-out turn at the far end of the lake) and the boat was in the air and landed on the pathway beside the lake. Not a problem, hardly a scratch, and it was put back in the water and has been run for 2 years or more since this "one-off" accident.
I have found it much more challenging to run a fast boat like this in confined space than going faster in a large open area where it can actually become a little boring unless you have somebody to race with. The only problem is the need to be courteous and not run it when the lake is busy and other users are enjoying sailing their scale models.
