RE: RC4WD 1/5 scale "Killer Krawler"
I don't know about that thing, at a glance it looks pretty cool, but the axles look like 1/10 axles with just larger output hubs at the end of the tubes, its using standard 540 size motors to turn tires that probably weigh in at 2 lbs each, and the speed controller appears to be for 540 size motors as well.
I understand that the electronics will be up to the end user, but I just don't think this was thought out very well, just rushed to market.
You would need axles that can take a bigger motor like a NEU or a Feigao (or even the new Losi 1/8 brushless) , a speed controller like the new Mamba Monster, and the appropriate gear reduction to handle one of these motors.
I can pretty much guarantee that this is gonna burn up any speed controller you use short of the big ones, and even then you will be cooking motors off without the proper gear reduction for the bigger motors.
Also, looks like they standard size servos in there, I wonder if it has the room to fit a larger 1/5 scale servo?? Standard size ones in a crawling application with those tiny gears trying to turn those massive tires in a crawling app will get destroyed regardless of what they(servo gears) are made out of.
Kudo's to RC4WD for starting in on a project like this, I think it has a lot of potential, but as I said, I think they should have taken their time and thought this project through a little bit more.
