hello ppl. ive seen a similar post like this but it didnt help much since my knuckles were in TERRIBLE condition. anyways my SE became super slow. the red gears and purple motor used to make it fly. i could use it on low pile carpet with ease. then without me knowing, the carpet fibers became stuck between the pin and the plastic of the knuckle. i was able to take some of the fibers out with tweasers as instructed from a previous post. but its so tight in there, no space to move with my large tweasers.
what i did was knock out the pin. it took forever. what i used was a screw dirver for tiny screws, kinda like the ones in the SE's. i found some crappy wood in my basement with a small hole. the hole was small enough so that the knuckle wouldnt fall through but so that the pin would. i hammered the pin out with the help of the screw driver.
the fibers were wound soooooo tight around the pin that the wheel couldnt spin freely on its own. i put the pin back but with a slightly larger gap than before. now it spins much better when i flick it. there was so much fiber that it was dragging the rest of the car.
now its really fast again. i almost gave up and bought a new one. i got so frustrated because i had tried everything. i thought my car had just gone bad. i spent hours of testing the different motors and gears. the best i got was the purple motor and the blue gears with the carpet fiber. now the car flies with the red gears. but to my suprise the blue gears and the purple motor still own.
anywho. for those of u who knew all this already sorry.
those who didnt. i hope this helps.
