RE: Caldera 10E speed run with Lipo
its better to ask 100 Q's then to figure this stuff out the way I have...LOL.
Ive shredded a few drivetrains...toasted some motors and such in my time.
Im working on a 1/5 scale brushless truck based off a Traxxas slash...used redcat 8e earthquake tires and a redcat Rampage body.
Dimentions right now are about 30 inches long, 17 inch wheel base and a 16 inch track. Its huge.
I built one out of a stampede a year or 2 ago, but this time around Ive modded the suspension better to give more width.
Anytime you get board with the hobby, you can always jump into a new segment/type or go crazy and build something totally unique. Or as you have found, upgrade what you got and make it perform very different. 2s and 3s lipos made a huge change in the truck, and a larger motor/esc combo will just add to the new top speed you have found.
