Rifle Doesn't Fire, Makes Weird Clicking Noise When Trigger Pulled, Video Included.

Do we have another case of one of those chargers with a dead circuit?

I've heard a few stories of those types doing that as well as having had one myself do the exact same thing.

the way to tell is if one or more of the led's doesnt change colour when charging.

also i'm guessing you gave that gearbox a clean before you photographed it? there should be some grease in there.....

It is fairly greased up but I guess you can't see it too much in the picture, and on my charger the 1 cell light is red when I charge it and changes to this purplish colour when it's done charging, and the 2 and 3 cell lights are always blue.

But they also sold you a Nuprol.  And yes, those cells should be balanced, and a freshly charged 2-cell lipo should be closer to 8.4V than 7.4V.

Sight unseen, I think your gearbox is fine, unless there's some burr that's catching on the piston.  If you can slide it freely back and forwards with the spring out then it should be OK though.

I'd suspect that's just a weak battery. Do you have a fresh battery that you can borrow from someone to rule one of them out?

Or if that charger isn't doing it's job, then we're liking the ISDT Q6 Nano as a cheap, effective unit at the moment.

Then if you're confident about the battery, you could treat it to a better motor.  Plenty of brand name opinions are available, and I've just been pleasantly surprised by a cheap Big Dragon "M140" motor from Ali Express.  I've got for "high torque" motors in my upgrades as I don't care about ROF, but I do care about avoiding lockups like you're getting.

Since you're clearly technically competent, you might consider rewiring the whole thing to Deans or XT60 using 16 awg wire while you're at it.

Yeh, mines on a slow boat from China at the moment along with some other RC gear I ordered. The unit only costs £21 and has got a colour IPS display and more functions than than the average Airsoft player will ever need. 

I've just received a ToolkitRC ADP100 power supply for £15 that plugs straight into the Q6 Nano. 

The whole setup is about a 8-9 quid more expensive than a basic (genuine) Imax B6 WITHOUT a power supply, but can supply double the wattage if needs be. Only limiting factor is that the Q6 Nano can only handle up to 4S LiPo's instead of the B6s 6S, but it's not an issue for my usage.

 
Thanks for the tips, I'm going to have to buy a new battery, do you have any recommendations for a nunchuck 2500-3000mah lipo?

I would ordinarily recommend Turnigy NanoTech from Hobbyking, but the UK warehouse is low on stock at the moment. 

The biggest thin nunchuck they have is 1400mah but with a 15C rating. They have 1300mah with a 25C rating. Both are 2s (don't run 3s in a Nuprol). But they are super cheap, less than £7, so buying 2 or 3 won't break the bank. 

I've been using NanoTechs for years in airsoft and RC.

Can confirm, I was just looking on there right now.  Not a lot of high capacity stuff.

I'm a fan of having two smaller capacity rather than one biggun, then swap at lunch.  I know there's an argument that you can over-draw and kersplode an under-rated battery, but I doubt that's going to be an issue for a stock Nuprol.

As long as it's not locking up...

I'm kind of surprised that OP's fuse hasn't popped.  There is a fuse in there, right?

Yeah, a higher 'C' rating is more important than mAh

Current = C x capacity, so both matter.

OP's Nuprol battery should be able to provide the claimed meaty 66A, but... Nuprol.  Then again, he's on a Nuprol stock motor.

I'm actually thinking that I should upgrade my batteries now that I'm on gruntier motors.

Yes, they both matter. The mAh is the total capacity per hour but 'C' is the maximum discharge current so if its too low then the battery will fail no matter what the mAh capacity.

For airsoft they should be at least 20C

Well now I'm stuck between switching the motor or switching the battery. Is there any test I could do to see which one is the faulty one?

 
Long term, batteries are consumables, a backup is always handy, and those cells aren't balanced, so it would be lowest risk and cost to try a new battery.

However, I'm also looking with suspicion at that VTE600 charger.  I have one but I was never happy with it: it ran hot and I wasn't confident about the circuitry given that (if I remember correctly) it changes the indicator light colours gradually rather than tripping on and off discretely.

Sadly there's no way to tell whether it's the charger or the battery at fault without replacing at least one of them.

 
I'd get a good battery and charger.  They're useful for any future AEGs too.

A good charger is important because it protects your investment in batteries.

Nuprol don't have a great reputation.

Ok cool, I saw someone mention the ISDT q6 nano earlier, would you guys recommend that aswell? I'd probably buy a charger with batteries to be safe.

Good reviews on YouTube. I've not heard anything bad about them in the RC community. I've got one on order, so will be able to give a better review when it arrives. Mine is actually intended to be used a field charger for when I go RC flying, using a 12v Leisure battery as a power source. 

They are available from UK retailers too, but they never stay in stock for very long. Hopefully that's a positive indication. 

I know a few guys with SkyRC S65s, less flashy (monochrome screen) but apparently solid performers. AC powered so no external supply needed, just plug into the wall socket and go. £32 on www.HobbyRc.co.uk (excellent UK company). 

I'm using some old CoreRC chargers that I picked up second hand for a tenner each as my 'home' chargers. They are old and slow, the balance logic is crap compared to newer designs, they've got the job done for the last couple of years but I will be replacing them soon.

I always run at least two chargers for redundancy, if one breaks I can still go flying or play Airsoft (guess how I learnt that particular lesson).

*Edit* invest in some LiPo charging bags, I normally use them but have left them out of the photo.

LiPo fires, whilst very rare, can be devastating. I store my LiPos in a Bat-Safe LiPo box in a shed down the end of the garden, well away from any property of significant value.

I ended up purchasing one of the turnigy nanotech 1300 2s 25-50c batteries, will update when it arrives.

 
I'd make sure you have a new charger before putting a new battery on that one. Judging by the fact the last 2 lights stay blue, i would say it's not charging up cell 2, and being that one of them is down to 3.3v which is pretty much as low as you want to safely go, I'd say that one is the one not charging ?

I'll see if the battery fixes it and if it does I'll get a new charger before fully charging the battery.

 
After looking a bit into chargers, I noticed that most of them require to be plugged into a power supply, which I do not have or intend to buy. Do you guys have any recommendations for a relatively cheap mains charger?
