    Mean machine build

    I just picked up a mean machine, which I don't have yet, with the following
    Includes:
    Wire Drive
    Wire Drive Coupler for 5mm Shaft
    SpeedMaster Mini Rudder
    Strut Assembly
    Carbon Filled Motor mount
    Thru Hull Water Pickup/Discharge
    Servo Mount
    Hitec HS-645MG Servo

    I am going to run a 9xl in it on a 4s lipo. I need a low cost esc at this time that will handle this.(just spent all my $ on lipos) I also need to know where to start with a prop. I was thinking the x440/3. Does this sound right?

    the 'mini rudder' will be marginal*, the mm needs a longer rudder to counter prop walk. I would use a 440 2 blade(or equivelent carbon prop) for the 1st 3 runs(till the drive line wears in)
    edit
    *the speedmaster 21 rudder works quite well.

      point taken. I was woundering about that.
      I was thinking of using this esc. Anyone running it?

        nother thing; that motor will tend to run hot. don't run the boat more than 5 minutes w/o a cool down(less than that if you're not running the long water jacket) I'm seeing temps around 135-140F after 4 minutes(using an x440/3).

              mean machine

              I agree with Rex on the motor runing hot and also on the rudder size. my mean machine has a 8xl and 120 hydra. after a bunch of prop experiments I settled on a 440-3 blade the boats a screamer on 2s. you will go crazy with a small rudder. I settled on the stock aeromarine rudder set back 3". Also watch your strut angle as much as you will want to bring the bow up the hull has a tendency to want to become airborn. Let the motor cool a bit between runs and you should have no problems just remember dont go to big on the prop size.

                              I have been busy. I have it all together. I am just wiating for some bullet connector, props and tubing to get here. I am very disappointed in the quality of the gel coat. It has many flaws like cracks or chunks missing on the canopy. The body work and paint are coming next.







                              Some of the flaws that need to be filled.
