What pinion are you using with the 5700 on 3S? Even with a 12T that would be a 50+mph car with the stock tires. I can see why that would run hot.

Let us know what you think of the 8L vs the 5700. I'm mostly interested in handling differences. I'd like to go 8L or 9L on 3S for the punch, but I don't want to loose the smooth handling my GTB/6.5 has at my local indoor track.

Updates:

Still waiting for servo saver arm and extended chassis, but I added a center plate and mounted the ESC and RX to it. It's hard to tell, but the plate is bent at both ends so the ESC and RX sits lower for more clearence and better cg placement.

Look what showed up today. The Jammin extended chassis kit and a servo saver parts kit arrived, now I can complete the project. I compared the stock chassis, a BCE chassis and the Jammin extended chassis, check the pictures. The BCE is just a tad longer than stock the Extended chassis is 15mm or so longer and wider. I have a Jammin CRT.5 wheel next to my Kyosho ST-RR 1/8 truggy wheel.


Parts are here.


Stock, BCE and Jammin extended


Extended chassis is longer and wider

Wow that Jammin extended chassis is quite a bit wider as well. Probably could almost lay the lipos don flat on the chassis for a lower cog.

How much heavier is the Jammin extended vs the stock Jammin chassis?

[Shark413]

jhautz, the chassis is wider but when laying down the battery it still hangs over the side of the chassis. Which means the body won't fit without bowing out and makes it vuneralble to a side impact hit.

I weighted the chassis and here is what my trusty digital postal scale came up with:

Stock chassis (bare) = 5 oz
BCE chassis (bare) = 5.8 oz
Extended Jammin chassis (bare) = 7.2 oz
