MT guys have long been swapping ALL bushing with ball bearing,, SEALED is the way to go. ebay seller TEAM BLUESTAR sells very nice sealed bearings. not sure if they have a CT4/CT5 package. but im sure if you got all the sizes you need and let them know, im willing to bet they ll make a package up for ya, i got a set for my Emax for 20.00 and 4 ship.... when i do mine, im doing them ALL.. every bearing in the car will be replaced and all busings will now become screw spacers when needed.. I HATE BUSHINGS. the only way i would use a bushing is if i had it machined or found it made of brass!!!! or its friday at 3pm, and i dont wanna drive for 30 min each way for a 3.00 part....
i ll look to my CT5 for this issue, but i havent noticed it yet. the minute i do. Bearing time. At that time I ll also swap radios and load it with a new JR RS310 Rx and USE my JR XS3 Pro Tx.. though i may like the anti lock feature of the stock controller, i dont think i ll have an issue if i dont have it. maybe the XS3 has it, time do dig up the manual again..lol
