Mack M75SX

[Espeefan]

That's a nice 1 ton dually you have there, Steve. I like the direction your Mack is headed too. I have to echo what the others said. Keep the axles. They are really nice. I'd suggest you just find yourself one big and brawny gearmotor to use as the transmission. We could calculate a good ratio for you, based on tire size, motor selection, and the voltage you want to run. As long as we know the motor's RPM per volt, or Kv rating, and an idea of how fast you want this thing to go.

thanks Nate , she's a work horse (bone stock) I got my speed issue taken care of . when I ran it the 1st time hauling 20 loads of coal it worked OK but I had a delay between fwd and rev . so I reprogramed the esc ( castle) to eliminate the delay . Also when I hooked it back up I desided to put the trotle on the throtle stick like evreyone else ( I know ) not realizing you have to reset the radio with the esc when you change parameters on the esc . now the bone head that put the shims in wrong on the fwd rear also did so on the rear rear so I'm getting there

couple weeks ago I tore the rears apart and re shimed them . I had to press a stel stop in the axle bore do to a change in direction since I machined the axle cassings I'm useing HPI savage ring and pinion assembly that has the shaft cups for the pin and ball shafts for independant suspension . well I machined the ID bore to keep them on not thinking the OD of the cups being close to the OD of the bearing . well I made my own axle shafts and eliminated the cups . So when I shimed up the diff and ran it a little the copper shims started working into the bore Now she'll pull like H@!! you can't put enough on it to stop it . Tonight I took a little time and mounted the oil tank and pump whille my wife helped pack up some orders to go in the mail tomorrow I also started on the cylinders a couple weeks ago . I did fix the front tire issue just added the foams from the distorted tires I have







thanks for lookin
