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 remember reading that these positions are not adjustable with the Traxxas, but it would be worth doublechecking that. What type of lighting kit are you looking for? I would assume it should work with a channel that goes "full lock". If all fails, you can actuate a mini switch with the servo to turn on/off the light. For the dump bed, you can install a buzzer and/or warning light to start once the bed leaves its resting position. Again, use a small switch, this time actuated by the dump bed itself. |

Tom, Would one of these switches work? Sounds like you need a 2 pole double throw RC controlled switch to activate the motor but only one speed with this setup.

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 not +100% and -100%, but +100% and 0%, a switch/relay like you suggested would be necessary, but I couldn't find whether or not the switch needs +100% and -100% to switch - if so, you have gained nothing (or at best a few bucks) over the ESC solution. |

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! Jens |

Hate to hear that about your eyes Tom. Hope you can get back at it soon I'm ready to see that bad boy haul a load.

D-9-joe and 9Wsteve-thanks a lot fellas. I am really looking forward to hauling a load of dirt. This truck seems like it has been almost done for months now. I have been ordering parts by USmail and that has to be the "WORST WAY POSSIBLE" to order something. Talk about slow!!

This is one of my favorite builds! I enjoyed the video. A lot of hard work went into this model, and it shows. It really does run nice, and it looks very scale. Sorry to hear about your eye. Hopefully it doesn't slow you down to much. The Cat 777D turned out great. At least you'll have some time to enjoy it now. Very smooth running, and I love the lights! You never did change the drive motors, did you? I recall you saying you thought they were a little to slow, but honestly, I think they are good. Nice scale speed.

From the tires, up, a really great piece of work! Dump and travel speeds very realistic, along with all the details, paint, and decals. An awesome model! Best wishes with the eye problems.
Ken

Well Tom, with all the troubles you had building this model and dealing with personal health issues, you have persevered to manufacture an outstanding built from scratch model dumptruck. Well done all around Tom!
![]() *applause* Waiting with great anticipation to see you fill it with your cable shovel. ![]()

9Wsteve-thanks a lot-I wish it wasn't 790 miles away. I'm sure it will be fun. Steamer-thanks- yes it is working great!! Not sure there will be another project. My eyes are getting really bad
