Smile Sand Rails
As a complete newb to this, I can't seem to grasp all the info I need from the various threads on these things. Firstly, should you lock the diff on a sand rail? With a brushless motor, do you have to get a new ESC, LiPo, and electronics? I'll have more Q's in the morning.

Cheers 8-)

Mine isnt locked, I wouldnt lock it...itll be hard to control it I would think...unless you wanna drift technique it. You need a Esc that is compatiable with brushless motors. Novak and LRP makes ESCs that do both. I run regular 3300 nimhs in mine.

The Mamba maxx will control both brushed and brushless motors too.

I would keep the diff open unless you are doing dune climbing.

I run the Novak SS5800 in my Sandrail, you have to have a brushless compatible ESC for a brushless motor. Listen to JRH on the Brushless stuff, he knows what he is talking about. I have an open diff. Don't go locked you don't need it. I also run either 3000 or 3300's in mine.

WERD!

John recommended the Mamba Maxx to me,I'm glad I went with it. It's a kicka$$ ESC. I've run both brushed and brushless motors on it and it's great. The programming aspect of it is awesome,you can fine tune any aspect of your powerplant and make it perform the way you want.

I like it best though cause it plays a little song for you when you turn it on.

It is actually the windings of the motor that make the noise

Why didn't the motor make a song when it was hooked to the Super Rooster then?

Turn the Brushless esc on with out a motor pluged in. Then do it with a motor pluged in. The noises are the ESC sending pulses to the windings when it is setting up.

My mind is made up, dumbass. The ESC sends pulses to the windings which make noise. Its the windings making the noises when they get the signal.

Nope,it may send a signal to the windings but the windings don't actually make the noise. If the windings are making the noise....my motor has learned how to be a ventriloquist. The noise is coming from the front of the rig but the motors is towards the back

Maybe it is different on the Mamba. Did you try unpluging the motor and seeing if it still makes the noise. I was always told that it is the windings of the motor that makes the noise. Here are two videos I just made explaining my point, one is with motor pluged in, the other is with it unpluged.

Motor pluged in

Motor unpluged

The noise is the ESC activating itself ,after it's made the connection with the motor.

I guess your gonna say that the TQ3 throttle spring makes a noise after you turn on the TQ3 also The Mamba also make the same tune after you turn the radio on as well. It's the ESC making connection and arming or activating itself.

You are not getting my point. Yes the ESC is activating and arming its self, but the noise is comming from the windings of the motor. I was alwasy told it was the windings making the noise. If you can find something proving that the noise is comming from inside the ESC show me.

Then why does it make the same noise when I turn on the TQ3?

Because like you said its activating its self, but the sound is still coming from the motor.

Will brushed motors make the noise also?

What about the middle ground? Maybe both of you are just hearing things?

It should sice the ESC is sending the pulses to cause the sound in the windings.

Maybe JRH will chime in when he gets on.
