sounds like the 10l is the way to go?

id just always run 6 or 7 cells, for now just 6 tho, 6 matched and zapped ib 4200's wce, i run them in my cyclone, and i cant afford anything else lol

i want to use my mm 5700 tho, will it run cool? well under 150 160? after like 15 20 mins?

Yeah, I probably will end up with the 1930, although I'll need a pretty low wind for 2s...

When you say glitching, do you mean the servo, or how the truck moves? I assumed you meant the servo acts erratically.

When I said glitching what was happening is that it would slam full brakes at one time or another. This makes driving very difficult and hard on the drivetrain. For example, I would be cursing along when it would suddenly slam the brakes for a split second, this would happen at half throttle or full throttle, not really at low throttle though. I do not think I am tripping the LVC either. Castle says if there is a short in the battery I could be intermittently resetting the esc. I don't know what to do, except that the next battery I am getting for this will be a flightpower.

That is odd. Do you have a failsafe (or Spektrum) that is set to brake when the radio loses signal? But then again, the receiver pack should have cured that. I didn't think the MM went full brake when it "rebooted".

Nope, no failsafe. I mean two different cars, two different servos, three different motors, two different esc's, two different radios(both FM), and two different receivers and the problem persists with the 3s not the 2s. So, the only thing it could be is the battery.

That brake slam thing does happen to me also once in a while and I have heard others say the same thing. But I'm running a Neu.... I don't recall it happening with a Castle motor. But I have seen similar but more subtle glitches with a stock MM combo in a 1/10 buggy.

That is very strange because the same is happening to me. I have only ran one battery pack through the buggy, and when I get going fairly fast, and then let it coast. The brakes somehow just lock up or the gears or something. I thought it was because I didn't have enough oil in the center diff (which I didn't) but now the center diff is rebuilt and I am waiting for my Spektrum radio system and charger to see if it will still do it.

What batteries are you using Cemetery?

An eagletree would help as well, you can also try the 3S pack with the lipo cutoff disabled.

Serum, I'm using maxamps 4000 3s 20c packs. There is an eagletree graph of these cells on page 26 provided by me. Also, I do not think I am tripping the LVC because it would happen if I am barely on the throttle...

***RC***, I don't think having any oil in the centre diff should cause it to lock up while coasting like you said, since if your coasting then the front and back wheels should be spinning the same speed as each other and the gears in the diff should only be spinning when the two outputs (shaft to front diff, and shaft to rear diff) are spinning at different speeds. If the gears inside the centre diff lock up it would just be like having a spool or a solid shaft (front and back diffs will get the same power), but it won't stop the car from rolling.

Is it possible that the ESC is simply misfiring the wrong coil once in a while?

Alright guys, I think I'm going to attribute this problem to radio interference. Even though I have tried two different radios and 3 different channels. Also, the glitching now happens on 2s, 3s, and 4s, so it has to be interference. I also did a test without brakes and it would not slam the brakes but would go into neutral instead.

All these tests were done in front of my house, so last night I went to a parking lot about a mile away from my house. I was there for about 20min and it only glitched about 4 times. I still don't know why it is doing this, I think I need a 2.4GHz radio...

Also, this problem suddenly came about almost a month ago, it never happened before. In my area I used to get interference on AM radios, but never FM until now. I cant figure this out.

Why would two esc's do this that have never done this before?

Well, I tried the buggy again with my new DX3.0, and it seems to be working perfectly. I also rebuilt the center diff, but Patrick said that wouldn't help, so I am assuming the 2.4GHz radio helped a lot. I rolls freely and doesn't lock up how it used to.

yeah, if u guys dont have a dsm 2.4 ght's setup, u NEED one for bl suff

makes driving soo much more fun
