Wondering if it is possible to run 2 Quark 33's, Revolvers and still use a 3rd channel dig? I would think it would be possible using the micro switch dig (each switch could cut power to the front or back). Just wondering since I have 3 Quark's and 3 Crawlmaster's sitting around.

No, you need to mix the 2 esc's with the 1st and 3rd channel. Then turn off the mix to lock the rear.

I think you could with a y spliter on channel 2 for both ESCs and channel 3 for the micro digs.

The micro digs will only work with a brushed motor. The brushless motors work on a different principle. Also brushless is realy not the right motor for these axles.

Ah! thats right. I forgot about the 3 phase power. You would have to cut the power to all 3 phases to not burn out the motor and then conect two in order to create the break. It would take a different kind of switch to work. Or stack three of the Radio shack switchs and a longer servo arm to activate all three at once and tie two poles together to make the break effect. SO 6 switchs and a mile of wire and a perfectly aligned servo to activate front and rear dig on a brushless/esc rig. The 3ch mix sound a lot easier ( but no rear dig)

You can't run 2 brushless motors off of one ESC, so your only real option is to run 2 ESC's on 2 channels and get dig with mixing. It can work quite well, but it takes a good radio and some practice.

Get a 4 channel radio, it's what I have to make it all work. Nomadio react, no sticks for me.

I guess you could cut the battery power on either esc, but no brakes. You could maybe rig up micro servos to jam their horns in the endbell for stopping power.

Maybe put a switch on the signal wire of the esc maybe the esc will just not respond and then stay in drag brake mode. Run a basic Y harness to connect both escs. Seems like a idea to me.

Or you could just run your brush motors and learn how to drive !! lol
Sell the brushless and buy me something nice, that sounds even better yet

I think you'd want the smoothness of brushed anyway, can I get on the get me something nice list?

RXcrawler · 07-05-2008, 08:23 PM

As much as my front motor hits the rocks, I wouldn't run brushless in a berg. I ran it on my clod and every time the motors touchs a rock it would stop pulling. It was funny you can ust put your finger on it and it will stop it.

Da Hermit · 07-05-2008, 08:25 PM

Mix...?
Can Anyone be kind enough to link me to a berg dig thread.
'Search' will not find the word DIG.

Sprint 80 · 07-05-2008, 09:24 PM

Are you planning to run a Berg???

Here's the first one I came across Robb, pics of your dig setup

You can adapt it to make a front only or both dig.

mchester · 08-17-2008, 08:46 PM

I wonder if anyone has been able to get a true freewheeling DIG on an axle mounted, high turn, brushed motor? It seems freewheel and brake mode operate the same in practice due to drag in the high turn motor. Am I missing something?
