Just got the boat for Christmas, it's my first foray into RC boating! The boat was pretty dull on Nimh, I clocked it at 26mph with the gps with 2 5000MaH 7.2's and an Octura x642. I then decided it wasn't enough so I soldered on all 5.5mm bullets from motor to esc, esc to batteries, and cut the bec wire and used a separate powerpack. Well, I just put the boat in the water about an hour ago with 2 turnigy packs (3s 4000mah and 2s 4000mah at 40C) and HOLY CRAP, one blip of the throttle took the boat completely out of the water and it did a flip in the air (luckily it landed upright, but it cracked the windshield)!!!!! The GPS wasn't giving an accurate reading, but this boat is simply ballistic on 5s, it's straight up frightening!!!

Questions for ya'll, am I ok running the 40-50c lipos, ESC and motor were only slightly warm to the touch after about 5-10 mins.
