Why did you change the ESC...?
I'll be back.

iamahuman

More power ;D

The stock motor produces quite a lot of power for a motor of its size. The ESC is good but may not be enough at times. To accommodate the additional weight, I upgraded my ESC. It can handle 1/8 motors in 1/8 applications so its going to be good in the slash. It will seem like overkill with the motor I have now. Once I get the other motor I've been thinking of, this ESC will make everything great. Its equivalent to the MMP. It doesn't have the throttle curve and brake curve adjustability but its got other setup options that the MMP has. It can handle 4s whereas the MMP can handle 6s. But, it doesn't have BEC problems like the MMP has especially when you go to higher draw servos.

And it actually helps the motor produce more power. I've had one guy tell me that just changing the ESC made the car feel like it was running the stock setup on 3s when he was on 2s. As of now, the stock ESC will stay as a spare. Once I get the motor, I might sell the stock system.

I just tried the ESC out with an NiMH that is close to being flat. It did feel like it was more powerful and had more grunt. I can't wait to try it out with the LiPo.

Gandhar let me know if you are selling the stock system :) can I use the vxl ESC with ripper motor without problems?

iamahuman

The VXL should handle the ripper....

I'll let you know if I'm selling it. I've already got two guys asking for it :D

As of now, it stays with me :P

I'll be sure to have a drag race against Divyam ;D
The chassis is really awesome. Superb structural strength. I've been in contact with the guy who made it and designed it and he knows his stuff. Its got flex built in where its needed. The top deck is just awesome. The fact that everything is as close as possible to the center helps as well. People have reported tons of steering with this. Looks like my dual rates have to be turned down.
Thanks for the compliments.

We'll do that :)

Divyam, I'll ask Joe if we can have the race this Sunday...

PS: I shimmed the front and rear diffs properly. The shimming I did yesterday was wrong. I had my spur gear aligned improperly and that necessitated huge shimming. I was told that one piece of paper from a Traxxas parts bag would do the trick. I opened the front and rear diff cases and shimmed them again. Now, the drivetrain is pretty smooth.

I found a slight problem. My front diff has basically no oil in it :o. One more thing to take care of at the track. Divyam, I'll need your help at the track when we meet.:)

Dude,pls explain the main motive of shimming, i just cant get it right..! Everytime i open the diff's case, i can barely manage to realise their use. And BTW how to shim the and what effect  can be seen? Is it for pure racing??
I'll be back.

iamahuman

This is a slightly different kind of shimming. Inside the diff, the spider gears may not align very well with the bevel gears. Shims are used to put them close to each other. They can also be used to remove the play inside the diff and diff case. I shimmed my diff case to space the input ring gear and the bevel gear on the diff. In the slash 4x4, those two are too close to have a good mesh. When you put a shim in between the bearing and the diff case, you space the diff from the ring gear just enough for it to have a proper mesh. This kind of shimming is mostly seen on the slash 4x4.

And shimming isn't only for racing. It can make your diffs last longer and your drivetrain smoother which leads to better runtime( in nitro and electric) and you can expect slightly cooler temps on the motor.

With the amount you know about RC, we HAVE to get together for our next rebuild ;)

I had sooner or later realized that it had something to do with removing that play...but other than that i had no idea!!
I'll be back.

iamahuman

Well, I hope I gave you a slight idea ;D
