Back again with my Rock Socker for its second outing. This time, I luckily got some quality driving time while my kids were happily occupied with sticks in the woods (kids will be kids, right?). So, what changed since the first run? I added new tires, more lights, and replaced the stock shocks – I'd heard they were the weak point and prone to leaks, and I didn't want to wait for that to happen.
To be honest, I didn't notice a huge difference with the new shocks, but at least they're less likely to leak. The new air-filled tires, though, that's a different story. I wasn't sure how much air to put in them (still figuring that out), and I ended up inflating them unevenly just by feel. It turns out that even slight differences in air pressure made each tire a slightly different size – not noticeable at first glance, but definitely felt when driving. A bit of steering trim helped keep it running straight for the time being.
These air tires are super bouncy compared to foam ones. The impact goes right to the chassis, making the shocks and springs work overtime. But, they're a breeze to clean after muddy runs, which is a huge plus.
And now, the fun part: we managed to break it. Driving through deep puddles, it almost felt like it was floating at times, with the wheels acting like a boat's propellers. Hilarious! Eventually, it just stopped – no throttle response, but the steering was fine. After the usual clean-up and a bit of TLC at home, it sprang back to life. My guess? The ESC might have gotten wet and triggered its protection mode, even though it's supposed to be waterproof. This is a bit frustrating since I could not pinpoint the actual issue.
I'm now planning to seal any possible openings in the ESC with heat-resistant sealant (already ordered some). I also found a few water drops inside the supposedly waterproof receiver box, so that's on my to-do list to replace as well.
I'll keep you all posted on this journey. It's proving to be a fun, educational, and creative project so far!
