Cat 777D Mining Truck

[modelman]

JensR-The only settings on channels-3&4-are servo reversing. The truck has no servos to hold a micro switch and their is no room to put one. Steve- thanks, the dual relay is what I am using on the dump box. The rocker switch will probably work the E200L-RC switch if I can find a place to put it. I still would like to have an actual-3-pos. switch to work to dump box. The"fake"-3-pos. switch will work the dump box but it will be all the way up and all the way down. No stopping in between. This is not ideal but I guess I can live with that. JensR-I really appreciate you trying to help. Sounds like you are really knowledgeable on this electronic stuff. I can barely turn on a radio! Your last post is "WAAY OVER MY HEAD". I don't understand but that is okay

This turned out beautiful... And the amazing thing is you built it from scratch.. even the tires... Very nice job

> "WAAY OVER MY HEAD".

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 rephrase my previous comment for completeness:

You know how a normal stick moves continuously from one extreme (-100%) over neutral (0%) to the other extreme (+100%).
If you have a two-position switch, it does not go continuously from -100 to 0 to +100%.
The switch only knows two positions from this range.
(A three-position switch should know three positions.)
If that switch in your radio knows -100 and +100, you can simply plug an ESC into the receiver. The ESC will be switched to full forward or full backward.
If however the switch knows only 0 and 100%, you might have problems:
Certainly with the ESC and maybe with the relay:
The ESC could then only be switched between standstill and forward.
For the relay it depends how it is designed.

Good luck!
