KWA M4 bearing HELP

Mar 24, 2011 10:23pm
I recently blew out the middle bearing of my kwa m4 cqb 1st generation running too high of a lipo. What replacement/upgrades are there? I know that I should be able factory replacements from KWA but would like to convert to something a little more reliable ie bushings or bushing bearings. Any thoughts or insight would be helpful. 1st gen has a mix of 8mm and 9mm so im not sure what to get. KWA says that they are out of stock but will call to make sure

bearings should give you less friction than bushings.....
Seek the Narrow Gate, for the path is broad and the gate is wide that leads to destruction.

Ya i kno haha i had just gotten it back from shop and had mosfet installed and wanted to try an 11.1v 25c i had laying around... wooooops. I just ordered two 7.4v 20c lipos to reduce stress on the gun

Bearings in a high rps or fps build will fail. Even with high grade kanzen bearings. Smartest thing to do is if you want to run that lipo and have a bps is go bushings.

ya i want to go over to bushings but they are hard to find for the kwa 1st gen gearbox. Looking right now at right around 25-27 bps. Does anybody kno of any bushing that will work with this gearbox?
