You may want to search the thread for more info but in general I haven't heard of people have success using the sidewinder in 4x4 SCT usage and I am not sure if castle even recommends it for that.

The MMP can be used but may need an external BEC and from what people have been saying it doesn't seem to deliver the power like the Tekin RX8. Some have also reported drops in temps when using the Tekin RX8 in comparison to the MMP. Considering the RX8 though was designed for 1/8 usage, not surprised lol.

Again, just what has been reported.

For me personally I have been using the Speed Passion GT2.0 Pro line of ESCs and it works great with the Tekin Pro4 motor I am using. A buddy of mine is using the newer Reventon Pro ESC which is even more powerful with success. For the money ($130ish for the Reventon Pro, $99 for the GT2.0 Pro), you get good bang for the buck.

Total power wise it's not too far off, but it has more natural drag brake and isn't as smooth which is more critical to lap times than pure power. If you're just getting your feet wet the Castle setup will suffice, but if you plan to race in the 4x4 SCT class for the forseeable future you'd save money in the long run investing in the RX8/Pro4 setup.

LOL. Fight time now Krio!

Bring it! I got the doctor recommended 8 hours of sleep last night, so there's no way I'll lose.

lol guys, thanks for the input. It came with the truck, so I'll just flip it and try to get some money back. thanks again!

Turns out this is a SCT version, does that help? Sorry for the newbie questions, this is my first Castle product.

hi. I did use 2x0.2mm under the sun gears and the stock shims on the outdrive.
Smooth as butter now.

Sidewinder: SV2 and SCT - both same, received a 30-40% increase in power delivery over original version. Castle says it can handle SC 4x4's

Mamba Max Pro: SCT or Normal version - great 1/10 or 1/8 sensored ESC. Most likely going to need an external BEC (battery elimination circuit). It has a programable one, but it is weak, especially with high voltage servos (Savox, etc.). For the price, it can compete with the RX8. Can pick them up for $90-100.

Mamba Monster: made for 1/8 non-sensored platforms. Overkill for 1/10. Good for running 1/8 motors.

it can compete, but will loose every time

Ignore him. A ESC has nothing to do with "winning" or not winning if it can finish a race. A Castle MMP has no problem on indoor tracks and medium loose tracks. The problem comes when you're running a larger track with alot of traction, you tend to over-volt the speedo and it starts becoming intermitent on it's reliability. This is a immediate turn off for a dedicated racer.

I raced an entire season before my MMP said goodnight. And I did very well. You will need a BEC and be gentle with the Sensor port, but it will work.

I switched because the MMP was not "reliable" in my 4x4 racing situation. I ran mmp's in my 2wd's and slash 4x4 racer for another year before I decided to streamline my garage into tekin. I also have several buddies who's kids run MMP's competitively in mod classes just fine.

That being said: There is a reason people run the bad-boy speedos. They "are" better. But don't go around believing these try-hard's statements that they are holding you back.

Thanks guys!

I ended up just adding another shim under the sun gear that came in the diff rebuild bag. Would it be wise to remove the shim between the cup and the diff? It doesnt seem to tight but last time I did that, the shims underneath the sun gear was concave.

Wow, Shaun, that was a great answer in addition to above... Thank you. I'll run it til she blows, or atleast until I can get an RX8. Just trying to get on the track this weekend, I'm already into Tekin's stuff, just need the funds to get some more!

Sc.
Honestly that is the exact same experience I had with them as we'll. but in te end it just didn't do the job as well as I liked. Now that I'm running the tekin. I can truly say that it is inferior. Yes it can do the job tho..

P.s.
Did you see my winky face icon guys?

I saw, but people nowadays don't know how to use that emoticon. So I assumed. Apologies.

I went from a MMP to an RX8 and it felt like I put a turbo in. Big difference, and I'm not even talking about the ESC issues the castle had. It just seemed to flow a lot more juice.
