Wow... talk about double talk.... I read the article in r/c nitro and it was one of the most missleading reports ever... I don't have a ct4s nor will I probably ever get one but the main difference in the article was the cen was faster top speed only... In a race the fusion was much quicker to speed... That was all...... Gee.. lets just add a sirio .21 and some different gears and go 88 mph.. I can do that with the cen and probably hit 90 mph... whats the point......I still get a laugh at all the worthless speed claims... It takes a huge area to get any vehicle up the that kind of speed and even more skill not to crash it... Want to try some real skill... drive a monster truck at over 50mph with stock tires... Now thats a skill....
