New Castle Products: X

[Kcaz25]

I love mine!! I can't believe you can buy this for like $140!!

The sensored part is really smooth. Not being stuck rolling backwards is amazing. For those that don't know sensorless systems have to find a stopped backward movement with the rotor for any micro second before it will go the opposite direction again. I could rock crawl with this thing its so smooth. lol almost.

he first thing I wanted to know where the dimensions.* The footprint is almost identical which is great. I am not sure about height. That wouldn't matter to most people. It has four caps. The old one had 3. The fan is easily serviceable. The case feels more solid. The motor and power wires face exactly as the old mmm does which is perfect for my setups. I love the red X on top. Those sorts of aesthetics are important to me. I shortened all the wires to match my setup except of course the sensor and fan wires.

I ran the castle link software through the esc pleasantly finding new features. Last time I got on castle link I had not seen the feature to limit the torque that new dynamic way. I had since heard about it but never seen it until a few days ago. I think its awesome! I left it alone for now though.

I think I left everything else pretty much default. I did changed brake power to 50%.

I have not figured out the aux function controls. The .9ms and 2ms explanation makes no sense to me.* I may have the numbers wrong but that part of the manual doesn't seem in sync with the rest of the user friendliness of the rest of the manual.

This is my gear ratio, voltage, kv, weight, and ambient temps: The vehicle is an 11lb truggy. South Alabama has had some crazy weather. I ran the truck the day after Christmas on Saturday. The ambient temp at the time was 75f. I was running in tall grass about 3 inches. Full throttle back and forth. The throttle would be all the way down for about 25 seconds. I would slow down only to turn around. The hottest I got the esc to read out was 123f. The fan never came on. The motor got to 136f.
