well guys i figured out what was clicking. it was in the spur i took it apart lube the bearings and put it back togther and it stop clicking. but after that i rolled it without a pinion and stil didnt roll to much futher. so i lube all the bearings and lossened the screws in the back of the top plat, just alittle and it seemed to roll alot futher. after i pulled out my pro 4 just to test to see how much futher it would roll and my hpi seemed to roll much futher then the tc5. so i dont know what to do know. i mean i got the tc5 to roll alot i mean alot further but my pro4 4 seems to roll even further
any suggestion ????
