i just switched to HB and i absolutely love it. ill will be getting more of them. they are so easy to drive. and you can NOT beat the price. i like the HB better than mugen but thats driver preference though. more and more people are switching to HB and one diehard Xray driver in my area just switched to HB and he said it handles way better than his Xray stuff did and he is now way faster. at this weekends georgia championship series race HB went 1 and 3 (me) in the truggy class and both of us never drove an HB till the race. i havent gotten the buggy yet so i didnt race buggy but he did and he was by far the fastest but he had a screw come out and wasnt able to finish the main, he was leading when it happened.
