I thought the discussion was the pros and cons of brushless vs. brushed in crawling applications. I will apologize if there was any misunderstanding, but I posted to show that I indeed have tried a brushless setup, albeit a cheap one, and compared it to what I have previously run in my SCX10 crawler. I haven't tried a high end brushless system...yet, so I have yet to make a definitive argument for myself about which is superior; merely making an assumption or a conclusion that if the cheap Integy, sensorless system works as it does, then surely a sensored system with a nicer ESC costing 3X as much will work better--how much better or whether it's worth the cost is another argument.
As it stands, I've only driven shaft-type crawlers and that my 10 year old Tekin with 10 year old handwound 30-turn spec motor still is smoother than my brand new Integy is testament to just how much more refined brushed--especially handwound systems--are compared to the relatively new brushless setups. I also remember that 10 to 12 years ago, I paid the same amount for said Tekin ESC and handwound motor as I did for the Integy setup today. That said, I make that case, that at least for the application that I currently use it,scale crawling, the difference is so small in terms of precision and driveability, that though I am not willing to recommend the Integy setup for everyone, I WILL recommend that people at least seek out someone that has one and try it out for themselves.
P.S. I have a Holmes Hobbies handwound on order to see what I'm missing. The only other handwounds that I've stuck in my crawlers is a 15 quad, 16 triple, and 13 double, all of which are WAY too fast and can't be geared down enough for me to just not launch the SCX10 into orbit.
