Hey guys I'm more to nitro, loving it so far! Today was the first time other than break in I've really got to run it. I'm pretty sure I've got it tuned pretty well, it was pulling wheelies and smoking good, although after about 20 minutes it began to bog down and eventually not move at all. I let it cool down and the same thing happend, runs great 20 min., then bogs down..I've done this about 4 times today. Any suggestions on what I may be doing wrong? Oh btw I have the 4901 2.5 maxx... Thanks in advance!
