RC Tank Warfare community hobby forum

Hi, I’m a new member (Brian) & hope I’m in the right section!
Our tank has stopped firing it’s BBs & just makes a lot of noise (no recoil either). Opening it up revealed a paint flake & BB stuck at the the Shooting Unit end. BUT removal hasn’t helped at all.
Any advice would be very much appreciated.

G’day Brian from the Gold Coast of Australia.
You are in the over all right place, but if you would be so kind as to drop into the introduction section towards the top of the main page, tell us a wee bit about yourself and what draws you into the hobby, Im certain you will get all the help you need

Great to have you along mate

Hi Herman, thanks for the welcome. I’ve happily introduced myself & look forward to being member. Brian

Are you using the rubbish BB's that came with the tank?
Because they will get stuck, and can damage the firing unit. Best place for those is the bin, then purchase some polished seamless BB's
It is possible that a wire has become unattached that operates the recoil.
But without relevant information, it's hard to work out what's wrong.
We need to know what make of tank you have, do you have barrel recoil, or is it your whole tank that lurches back when firing?
Are you able to film what your tank does when firing, then upload it to YouTube so we can see.

The film is more for the sound

Hi, thanks for responding. It’s a Heng Long M1A2 Abrams (No. 3981-1). Yes, we’re using the yellow BBs, they seem to have been ok so far but after your comments I wonder if there’s one jammed in the firing unit itself. All the cables appear ok but I’ll remove & check inside the firing unit itself (not tried that before so fingers crossed!).
But as I say, all it does now when instructing it to fire is make a lot more noise without shooting.
We do have some much higher quality BBs so when (if) get this sorted we’ll use those as you suggest. I can’t upload to YouTube as I only watch it & don’t have an account.

Did you just edit the title
It's easy to get a YouTube account, and doesn't cost anything.
It's that "lot more noise" that would be more helpful to hear, unless you're a dab hand at writing sound effects like in a comic lol.

Ha ha, ok I’ll investigate the possible jam inside the unit as it fits in with what happened plus I’ll open a YouTube account. Thanks for your help so far, I’ll be back tomorrow!

My pick too that a BB is stuck.
The units are a little finicky to open and work on, but thats if you are confident to do so.
Could be just as easy to buy a new unit so when you open the turret you are not bothered to muck around repairing when a new one is to hand. Then you can use better quality BB's through the new unit.

And with that introduction, we now know you're happy to tinker and confident with taking things apart
This makes giving advice a bit easier

Going on what Herman stated about getting a new BB unit, they are usually inexpensive and easy to obtain here in England. Therefore, if you can't fix the problem, don't despair, there's always an alternative.
I'm sure these units have a micro switch that triggers the tank recoil/lurch, when it goes through its firing sequence. There is a possibility the plastic gears inside the unit are damaged through trying to fire with a jammed BB.
