hi guys.. first prob with this gun... went to fire and half pulled the trigger.. bb jammed, cleard ok no prob, but wont fire now? any help much appreciated!

Define 'not firing'. Is there any noise when you pull the trigger?

no leaf clover

yup a sad attempt by the gearbox, sounds like its tryin to force the piston with no success

**could actually just be a low battery coinciding with the jam.. ** will tell ya tomro morning!

no leaf clover

damn... charged the battery for a bit last nite.. and it shot one, but then finished the charge, tried this morning, and its just like locking, when i pull the trigger there's a small click.... anyone any ideas?

could be a problem with the mag. is it the high cap one you get with it?
mid caps work better and are less noisy.

sounds like your gearbox is locked up, sometimes this can resolve itself if you leave it alone for a few days and the tension will ease up and next time you fire it will work, other times it means opening the gearbox to release everything and putting it back together

kk.. will give it a couple of days.. how hard is that?? could i remove the gearbox, and try see will it move when not in contact with the piston?

Stercus Accidit

Unfortunately the gearbox contains the piston, so no.

Opening it up mightnt be the end of the world, just make sure you research it before hand.

no leaf clover: check out mechbox.com for a disassembly guide for the m4 and for the v2 gearbox
the m4 used on mechbox.com is a TM, so although there will be slight differences to the dboys one, they are basically the same to take apart

well this has happened to me,the trigger might not be pushing the metal inside together which sends the current from the batthery to the motor.

kdouglas

if it's making a dull clicking sound as he said, then the current is definitely getting to the motor

RC car fanatic

i thought he meant it was from the trigger not motor

no leaf clover

motor is definitely turning.. so ill take it its jammed in the gearbox somewhere? ill have fun figuring that oout!!! is it a common problem?

kdouglas

it can happen occasionally, most common cause of it (from what i've heard) is double tapping in single shot too quickly, causes the gearbox to jam up

Can anyone advise me - is there an easy was to remove the "plug" opposite the fire selector switch (the opposite side of the receiver). It has a little nick in it - I assume this means there is a thread on it.
Does anyone know if it clockwise or anti (I assume it's anti).
Indeed, anyone have a better suggestion regarding tightening the switch?
(the gearbox is out btw.)

Need to get it out to tighten the fire selector switch screw which is almost out from yesterday. It must have been catching in my rig - note to self for future

Come to think of it - replacing the philips screw with a small allen screw could be a better idea...

Damn thats an awesome job Defenderdude,il pm ya later me wants a job like that

defenderdude

Thanks m8, but I'd hoped it would be better.:( Have to start somewhere...
I'll drag it up to HRTA on Saturday and you can have a look at it.
I was a bit disappointed to find the grip, barrell heat guards and stock all appear to be some type of nylon - basically the paint wont stay on forever... I had hoped it was ABS or similar.
However, I have a special polypropelyne/nylon primer on its way to me soon and that should sort that problem.:)

Other than that, reasonably happy with it. Talk to you saturday Gat!
