RE: Redcat "rockslide" crawler
I just got the Redcat Rockslide today, so here are some first impressions:
Mostly plastic, but seems durable enough for casual use. Seems to have a pretty soft suspension (I'm not an RC veteran) and good articulation, with no binding so far.
The electronics have a smooth response, no 'idle to full on' throttle response, steering is also smooth. The RTR RC unit has several options for steering and trim, and the range appears good - over 100 ft right now.
I like the 4WS and the option to go 'crab' or rear steer only. I have a loose rock/rubble hill just outside, and today I tried going up at both an angle and straight up. I got cleanly up both times with minimal wheel spin, so the lack of locking diffs didn't hamper me. Another nice 'crawling' thing, the speed! It seems to have a top speed of about 4mph or so on the flat, and if 2 standard 6 cell stick batteries are used (only comes with one but has room for a second) the running time should be quite long. It seems Redcat's 100T 540 motors do the torque/speed tradeoff rather well.
It has good ground clearance (remember, I'm basically an RC noob) and while it has 8 shocks, it isn't a 'stiff' suspension. The tires had only a bit of wheel spin on my rubble pile, and grabbed the slickrock sections prety well.
Redcat advertises this as a casual crawler for firsttimers, and, to me anyway, seems to have a solid product. I'll try challenging it a bit more in the next week or two, and post my results - or lack thereof.
