Thanks Man! So you can run a 14XL on 24 cells? WOW. I did not know this.

A great thread, thanks RW. That total $ does exclude the second most expensive part - the cells. And 24 cells through a single direct drive XL is a lot, but it works for the OP.

An alternate plan with the same hull is to use a more conservative approach. IMO the MM is too small for 24 cells and works better with 12 to 18. Mine ran in the mid/high-30s on 12 IB3600 cells and a 10XL for 4+ minutes, or 45 mph with a hotter XL motor. I've hit mid 50s with 4S LiPos and a Neu motor running one mile oval heats, so the MM hull can handle power without the weight.

I guess all this proves is that there is more than one way to have fun with this hull without breaking the bank. :)

Wow. How have they held up?

Are you getting a lot of water in your boat from the drive line? Add a drive Line seal. Use a rubber grommet or a piece of water line.

Ready is right, I tend to think in terms of higher end cells; less potent cells deliver less power and the motors last longer.

OTOH, I ran my MM tonight with the 4S/Neu setup on fairly smooth water and here is the GPS. Five laps on a 1/10th mile course (it was a handful in the turns) and the motor was 115F, the ESC was 130F and the packs were 100F :)

WOW!, did you hear a sonic boom when it broke 60? This is a better hull than I first thought. What is its limit???

**Fluid** · 06-28-2007, 09:30 PM

This is probably faster than you could ever race it with other boats, race water would be too rough. I had to throttle it in the tight turns I had, but on the legal 1/6th mile course this would be a fun boat!

There is more speed there if all we wanted was SAW running, I used a small prop and no spoilers to keep the bow down. But on smooth water it behaved well and I could do some more tuning to settle it down a bit. But I'm like you, the hull is better than I expected. The main thing I have to concentrate on now is tuning for turning.

Niiiiiiiiiiiiiiiiiiiiiice.......60MPH is fast man.

**hkusp45** · 06-29-2007, 07:58 AM

WOW!!!

Im impressed! I would have never guessed 60 mph!!

**ReddyWatts** · 07-05-2007, 01:13 PM

Maybe Fluid could post some pictures of his 60 mph setup for us?

**Fluid** · 07-05-2007, 06:20 PM

Sure, here ya go. But really, going fast is just a matter of setup and power. Power is money. The power level of this 60 mph setup is really too much for the hull except on flat water. I could never oval race it with other boats and keep it upright....the boat is just too small. But a prop with less pitch would bring the speed down and not rob much acceleration, that will be the next thing to try. I need to reduce the length of the power wires too, they are way too long.

Well there you have it. Choose a Mean Machine "Sport" or "Race" setup, all from one thread. Get to it, start building!

**yz120** · 07-05-2007, 06:39 PM

thanks guys.
your setups both look good.
