Lose Semi when motor gets hot.
 

Hey guys, i have a G&G MP5. Not sure what the exact model is. It fires great, in semi and full auto, until the motor gets hot. When it gets hot, it just completely loses semi, and both semi and full auto settings... fire full auto.

Any ideas? Once the gearbox locked up on me, and a 2nd time someone pulled so hard on the trigger, my tech told me the trigger "slipped past" the trigger contacts. Could this be related?

What battery are you using? Sounds like the trigger contacts are arcing and sticking

I've completely lost semi now after the winter, put a battery in to test the fps and i only have full auto, the gun is also vibrating a lot while firing and the sector switch just kind of vibrates between the semi and full auto position of i do a burst.

What do you think has broken?

no use in guessing at this point, it has to be taken apart regardless. Take it to a tech
