Re: Radios
That's high-quality kit right there.
But it's also quite a bit of money.
I'm not sure if money is an issue for you, but if it is:

Re: Tournarocker Diversion Build
These motors are close to the RB35 (popular in Europe) and even come in more rpm choices:

Re: Tournarocker Diversion Build
Some things to consider:
Angle the whole assembly slighty (or a lot) upwards. This might offer a bit of space.
Use motors with non-concentric (eccentric) output shafts and arrange them so that...

Re: Mack LRVSW
Looks fantastic! Great to see the overview of the beast!
The bed frame/channels from aluminium look good to me in proportion.
So, my honest question: What would be gained by doing them in brass?...

Re: Cat 777D Mining Truck

Sorry, didn't know how to say it simple.
But it seems you already got the relay, and you are also very short for space, so my point was moot.
But allow me to...

Re: Cat 777D Mining Truck
Tom might be able to "switch" the ESC.
If the radio sets the servo full left or full right, this corresponds to up (forward) or down (reverse) with the ESC.
If the command from the receiver is...

Re: Cat 777D Mining Truck
A switch is basically just a potentiometer with two (or three or in some cases even more)) settings.
So it really depends what positions the switch tells the receiver to move the servos to. I...

Re: Cat 777D Mining Truck
I cannot really comment on the wiring issue, as I don't know how it looks inside.
However, I do believe that two "half channels" with two servo positions each is all you need:

Re: CAT Grader in 1:14 with M-Series controls
Thanks guys :)
D/R on the forward/reverse gives you a much finer-grained control on the stick.
With D/R the full stick movement means only half (or so) of the speed, so it makes...

You are right about the lurching.
I did have Dual/Rate programmed. (That's the red button in my earlier video of the controls.)

Not sure I would classify that hydraulic as low budget, though ;)
I _would_ class this build as very awesome, though :)
