collet
 

i have a O.S engine it's a .18tz-tx and i want to know is there a certain collet to use on it to keep the flywheel from slipping loose? i checked out tower hobbie but os doesn't have one

RE: collet
 

If the collet you have wont grab just sand down the top down a millimeter and sand the little gap in it a bit bigger. Then the collet can go farther into the flywheel and the bigger gap will make it close up more. Worked like a charm for me :eek:
