It needs to push the metal enough to click the switch. This is mine:

here's my dig setup....

Toy4crawling had my question also.

The switch is rated for 5 amps.

Is the 5 amp rating for "switched state"?
Which wouldn't mean anything since we use them for shorting.

Or is the 5 amp rating for "normal state"?
Bursting 35 amps thru them doesn't seem to be hurting them at all.

They are rated 5 amps at 120 volts. 5x120= 600 watts
600 watts divided by 11.1v = 54 amps

So on a 3 cell lipo they would be rated for 54 amps right? Or am I missing something?

it is possible to set up front and rear dig with dual goats with a three channel radio. according to novak it can't be done. Me and my buddy did it in less then 5min. all you do is use the signal wire to the esc instead of using the motor wires, so with the help of this thread, it can be done:lol:

When you turn switch off to the signal wire going to the esc. The esc blinks once and then applys drag brake. So for about a 2 seconds you have freewheel on the esc being turned off. And instant power when truned back on. It works great. Its nice to be able to use the freewheel when i want it. Or hesitate 2 seconds and have full drag. I have contol of how much drag brake i want each axle by setting it in the esc for that axle. When you have full drag brake. Its a true lock. The tires do not move at full drag.. and if you want a it to roll a little when digging you can set it to do that too.

The only problem i have ran into is sometime when you are trying to do a dig while on a steep incline it wants to roll back while it blinks and then applys drag brake.. But its easy to counter it by adding a little wheel spin with the front axle.

idk how often people check here, but how big can the holes in the switchs be opened up? can they be drilled to 3M? trying to figure out how to mount them

Yes the radio shack ones can. I drill mine out to M3 and run screws through them to mount them. I cant speak for other brands of switches.

great, thanks. thats exactly what im planning to do. and yes they are RS switches

sweet, clodsrule is going to help me with mine!

cutting one motor off is like putting on a parking break...i see no advantage to that

try it. I think you'll like it.;-)

You lock up the rear axle, turn the front wheels all the way in one direction, hit the throttle and turn on a dime.

It keeps you from having to use reverse to make tight turns.

Exactly!! Also will aid in climbs, and lining up for the next gate as well...

Wanted to thank you for the great idea. Really cleans up the wiring of the chassis. I put the BEC inside and will have the reciever on the outside for the cleanest setup possible.
Works well to pass wires through that go front to back as well, such as my battery up front to get to the ESC in back.

Hi, new to the whole dig thing and Rc crawling. I want to try this set up on my Cliff Climber since they have MOA. (don't laugh) This will work with a 3 channel radio? It gives you front and rear dig? Thanks :?:

I used Hitec HS-82. Metal geared. $22

I agree with this. I just aquired a nice Berg crawler with this setup but am waiting on an Rx before I can run it. Unless you disconnect the actual gear train, doesnt it just drag and slide. Like I said, I have not tried it yet but I just cant see it working like a disconnected gear train.

Does anyone have video of how this can actually help?

You want it to lock up. It works like cutting brakes. The rear stays locked in place, while the front drags the truck to the left or the right.

This is the best example I've seen. Credit goes to Kamikazi for the video and the excelent driving."thumbsup"

you can see how he uses the front and rear dig to drag the truck sideways by switching back and forth between rear and front dig.

If either end of the truck was in free wheel, he would've driven off the rock of taken out a gate.
