Hi All. I'm a newbie and I've got my new ET48.3 up and running and love it! I used the old electronics (MXL-6s and 2200kV motor) from my ERevo Brushless Gen1 and I'm using a 15T pinion. I run 90% of the time in the backyard grass on a course that we setup. So the vehicle is running hard, non-stop until the battery dies. The first run, my Traxxas batteries got so hot that a wire unsoldered itself from the connector and the motor was extremely hot.

So, after reading a bunch of forum posts, I realized I needed a better battery and smaller pinion. I bought and installed a 13T pinion and a Reedy Zappers SG2 6400mAh battery using 5mm connectors straight to the Traxxas MXL-6s ESC. This helped. The battery was warm, but not to hot. Wires were OK. Motor was still pretty hot though (but not as much as last time). I will get a temp gun and measure it next time.

I'm realizing that I need to replace the ESC and Motor from the eRevo with something that better suited for the heavier ET48.3 and the grass surface I run in most of the time. On the FAQ section of Tekno's website, they list the Tekin RX8 Gen3 with a T8 motor (2000kv?). I almost bought that until I realized that it's not waterproof. Since I sometimes run in wet grass and about 1" of snow I need something waterproof.

I prefer a setup that favors reliability over performance and I'm willing to pay for a more expensive setup.

I run 4S and don't plan on running 6S because it seems like 6S will lead to a less reliable setup.

So the Tekin RX4 ESC and ROC412 (1800kv) motor caught my attention. But those components are always mentioned as "Rock Crawler" Electronics. I'm not doing "Rock Crawling" just backyard Grass Racing and Bashing.

Any advice? Will the RX4 and ROC412 be a good choice? I was thinking the 1800kv would have the torque I need for running in grass. Is that true?

Thanks!
 
Sorry, I realized I posted this in the EB section. My mistake. I'll re-post in the ET section.
