Rob

The Beast is performing with stellor power, looking forward to slobbering over it next wkend. :D

Are you using a FM or 2.4 radio?

Joe , I'm using a DX8 ,I have all my models on it for now till I get more radios . I'm thinking of a DX10 for the 385 and kobelco blade runner . I may glue the tires after I paint or find /cast like tom did more scale looking 1's . These are too wide to begin with . I'm using a 645MG servo for steering , I think it's about all it can handle loaded . I think It's drawing all it can thus interrupting the motor ,IDK :confused: Now to get this loader running :D

Truck looks really good steve-I like the way it bounces when loaded. Kinda like the real ones. Do you need me to make you some tires that will stay on the rims:D:D? Nice job.

Awesome, Awesome, Awesome!! You can see the torque, bout' does a wheelie. Great job Steve! What does it weigh as it stands now, how much do you thing the load weighed? I wanna try it, can I have a turn?

Steve, you hit a home run with this bad-boy! It is large, but seems like plenty of power with the two motors, and acts like a real one - carries plenty of payload. It will look so much different when painted.

Want to see it first-hand sometime.

That looks just awesome. Slower would be more scale probably but sometimes its nice to be a little fast to get around. You need some solid tires for sure with those impressive loads!:D

thanks Tom , the tire should be narrower ( 1" wide ) to be within scale . But they work . I thought about glueing them after I get it painted (long way off yet ) I like the bounce too , it reminds me of the real 1's I use to watch waiting to get loaded at the quarry I seen them running in . those where m45's single axle . I think they scrapped them by now :(

Ben , I put my 55# daughter in it last night and pulled her around like nothing . That was about all the 645mg steering servo could handle .

Man, I love the Mack M series trucks. Some of the coolest Prime Movers I have ever seen are Mack M's. Jusy massive trucks.

Looks cool getting hauled by your IH heavy hauler, killer combo!

Dang Steve, you really need to buy a better camera! I know it cuts into your funds for tooling, but how are we ever going to fully appreciate the craftsmanship? :D

I know Nate :o actually not , something else takes those funds and will for another 2 years :(:(:( I still got obligations to fullfill from when income was steady till '08' hit :( . It worked the best on sunday at cabin fever after I put in an external bec and started gluing the tires . I had to consentrate on feathering the throtle to keep the spinouts down :o . I meet a guy at the show who took the pic of the real 1 in the mack history book and knew of some of the smaller mseries in my area . He told me the M75's didn't like to steer just like the model . Someday , I'll be running out to NJ to see the real 1 in mack history book .

Awesome truck and great combo! :)

For the camera, you can put it onto a bean bag (which you can make yourself) or just something that is stable and a bit off the ground, like a few books or aluminium blocks ;) , this prevents camera shake.
If you then use the self timer, it will be even sharper.
Also, for close shots, using the macro mode might be necessary to get sharp shots.

Here is a few history shots from where Stevie's M75 evolved.

By the looks of the Mack cab I would say that Euclid copied them as close as they could. It's like they had the same mother but different fathers.Haha.

thanks Steve , I'm trying to picture in my head where that pit is :confused: I heard the name of the co. somewhere . if you get on 209 from port carbon Pottsville head to Tamoqua Its like your driving through a trench . sometimes you can see some small drags working on the banks . all you see is the boom maybe a glimer of red/orange in the trees I've did some home excavations in those hills . 18% grade roads is the norm :eek: I'm wandering who really made the frames for those trucks . My dad worked for a co in 60's/70's (before I came in this messed up world :p ) that dug some of the fondation work at mack for the machines to make the rear axles on those trucks .I'm going to have to make a short trip to the mack histiric center someday , you up to it Scott ?
