5.25lb Cat

[Rctothend]

Well if anyone had any question if a Castle Mamba Maxx esc would be ok to run in a boat, the answer is yes. It has a 100amp continuous rating and works well in this combo. The boat is a Kyosho Hurricane, a heavy ABS catamaran from the 80's I think, which I gutted, except for that neat radio tray and hatch mounting post. Then removed the big gnarly skeg that supported the original driveshaft, smoothed out the bottom with a filler piece, and ran a 0.130 cable to the strut. I made a motormount and attached a Fiego 10xl, the wind that Steve suggested. Thanks Steve, you were spot on when I asked you about this earlier. The hardware is Octura offshore type with the rudder behind the prop, which is a Graupner carbon 40mm k prop. I've run 10 and 11 cell packs so far, going to try 12 cells soon with a 42mm. The motor never got hotter than 105 degrees and the esc ran cold. Not sure of the top speed but it stayed high out of the water on top of a slight chop with a nice roost. Lo to mid 20s, I'm guessing, definitly fast enough to keep it interesting. It's a fun project with room for improvement. The radio is a Spektrum dx2 which works great on the water bty. I don't post often but I read regularly. Thanks all, for the ideas and info....Greg.....

We have used the Mamba Max in a few boats. They work well. Just keep them cool and DRY!

i just used the bk 9920 warrior out of my e-maxx the other day and it ran cooler than the other components, with out a fan

Here are some pics. The running shot is from last year, it looks alot faster than it was with a brushed 550 and 10 cells. Much better now with the current setup.

Funny you should mention the E-maxx. That is what I pulled the Mamba Max, 10xl combo out of. Wheely popping, universal snapping fun. I need to get the MIP universals before I put that motor back in. What's the current rating on the BK?

sermoss lol change it to atleast deans connectors

I second that, to use deans connectors. They can handle more current. I would also get the water cooling jacket made for that motor. It will cool the motor a lot better because the water makes contact with the metal shell.

the bk warrior is rated 99 amp 20 cell its not bad for $150, yes the mip shafts are a must all aroud the truck, this truck has a 14" wheel base and nothing keeps the wheels on the ground, i tore the diff up so i am putting a spool back in it to run a 9xl 18 cell

Real good advice!!!

Awesome Cat!! I just love those old Kyosho boats. Verry clean build/mod. I would like to see some video. In the picture she looks to be running a tick wet. You maybe able to pick up a few mph by moving the cg back. Hard to say though with out seing her in action.
