Glad to see this thread take off a bit. I am also working on speedin up an apache 24. So far I put in a Trinity 19 turn motor and built a 8 cell nicad pack for it and switched it to deans connectors. Total cost of upgrades is $35 for the motor, the battery's were a good freinds leftover loose cells. With the 8 cell pack the boat almost flips backwards when you hit the throttle from a stop. Lots of fun for my small pond, I don't think I need to go brushless but I will admit to having the itch. I just really need to know what prop to put in it, it is running way way too hot. Oh, to get the battery in with the two extra cells (twin turbo ;-) just cut the bottom layer of platic out of the hatch below the cockpit areas. See pics. Oh, and the battery is my first attempt but I had a great time doing it. I can't wait to build more.
