Jabbran,

Mine is actually from the ebay distributor and came "reciever ready" with motor and ESC installed. Although the hull in the link you posted looks exactly the same. All I had to add was a radio system (transmitter/reciever and 1 servo for steering). Any 2channel radio system should work with this just fine, and any standard servo should work as well. The boat is small and light enough no special servo is needed. In fact i'm running mine with a Futaba S148 (the stock servo that comes with most Futaba radio sets). I think the tiny hull is defintly meant to run with li-pos, just because of the weight consideration. 3S would be ideal for the stock configuration as the motor is comes with 2880kv, is high on the
KV side. It will get hot on extended runs on 4s, on 3s its within its limits. 3s also helps keep the cost of batteries down. I bought this hull expecting "not much" but was very pleasntly surprised how well the hull handles.. it handles and drives like a "true" race boat- I would not hesitate at all to race this thing, and it would be very competitive with all the stock hardware. If you are going to push it hard read- extended runtime on 4s, or start getting silly with 5-6s, you will find the limits of the stock motor first (simply to high a KV to run on huge voltages), and the ESC second. The ESC that came with mine was an 85 amp unit capable of 7S!- I think that is much more than the specs on either of the Aqucraft boats....
