Well, its official, I became a victim to another bunk 490 motor failure yesterday. This is the 2nd failure of the 490 in my gun. The first right out of the box it was bad. The 2nd came to a head yesterday. About 2weeks ago I noticed a bit of an odd whine from the gun on longer sets of burst, the noise sounds like the typical low battery sound so I changed battery, didn't fix anything, noise still there. So I started to do my research and reliezed its possible I have another motor failure coming. Luckily I have a spare 490b in our "PTW kit" in case so I went on with my playing. Did a milsim last saturday, gun ran ok as long as I didn't make extended bursts or it would start to hear the whine noise but as soon as I stopped firing for a second the noise was gone until I did the extended burst again. Only hickup for the day was a result of a bad bb that got jammed in the hopup and such caused the fuse to blow and at one point the gun only first in burst but it was raining so I counted that to moisture in the gun.. Easy fix. Fast forward to yesterday. Instead of having a game day a few of us with PTW's figured it would be a great day to attempt a few maintenance things (cylinder rebuilds, hopup rubber replacement,etc). My gun ran ok, at first it didn't want to fire in burst, semi only. After a few dozen rounds it started to shoot on burst again and everything seemed ok so I put another 250-350 rds through it with only issue being every so often it wouldnt fire.
Well I then decided to take a problem mag I have apart to try and remedy issue of not feeding well, well I took it apart and fixed it up. Put it back into the gun and give it a few rounds to test it out. Well after about 5 burst through my gun it just stopped. I thought it might be related to some water in the electronics from the milsim so I checked the fuse and took the gun apart. Everything seemed ok so I figured I would try my spare 490b. Sure enough, it fixed all the problems I have been having with my PTW. In fact the gun sounds so different now, maybe I got use to the old motor going it or be it slowly just deteriated, either way, its got the nice crisp snap again that I love so much.
Anyways I thought I would share my story,maybe someone else is facing the same issue.
