I know, but comparing my truck to this video where he is using the included battery : http://www.youtube.com/watch?v=MbRAGuXmPZM, mine isnt close to that.

I know it's not a full charge aswell, but i'd expect even a half charge to give a good indication of the power in the system. My brushless cars of the past were just as quick at half charge pretty much, as they were at full charge.

I'll give it a proper going over tomorrow, and try get a snow video using the phone I get tomorrow when it arrives! :)

Had it out today in the snow, and it suddenly started cogging, really badly. To the point where you almost need to stay on full throttle to avoid it. Batteries are fine (Using the standard packs), sometimes the steering servo -when turned slowly and not moving the truck- doesn't respond until you give a bit of throttle, even a single 'cog' to send some power through the truck. I tried changing the CH1 position on the reciever and the problem remains. I also re-linked the Tx/Rx, still the same problem.

Here is a video of what happens when I put two 6 cell packs in series and try to run the truck:

Any thoughts?

To me it sounds like the battery is crap. It could be dropping to a low voltage and causing drop outs in the rx. Would explain the weak servo and low power output.

Are you sure you are running them in series? That's ~12-14V+
If that's true, you may have other problems...

Yup, the video was done in series. I have tried a single pack and two in parallel, all with the same result.

Both batteries are pretty much fully charged.

Try disconnecting the servo, try another receiver and radio, and go over the wires to make sure its all connected tight and right.

It almost sounds like there is a pebble in the gears or something

Checked everything just now, everything's connected fine. Tried disconnecting the servo and still had the same problem.

I don't think there is, everything's sealed and if you put it on a single 6 cell pack, the wheels will spin consistantly as long as you give it 60%+ throttle.


I'm starting to think that the ESC is at fault and I should just return it to get replaced under warranty? Also the front bulkheads have a few 'holes' in them. Like there has been bubbles in the plastic moulds :neutral:, interesting.

I had a "hole" in my front bulk too. I figured out what it was for though, just before I sold it I had to replace the front diff. There is a long screw that you access through that hole after you pull the suspension pin out

Aah, that makes sense.

On the plus-side. I tried the revo again this morning, and its fine :mdr:.

What did you do to fix it. Did you read the manual or was it some other last resort?:mdr:

Literally nothing. Turned it on and it worked. Could have been a tiny drop of water on a connector or something?
