Double Eagle M904g – Aka the Original Q Honey Badger

[Fatboy40]

How did you turn yours into a DMR, cover the full auto optical sensor or stop the selector plate moving that far?

Stopped the selector plate moving that far with a nut and bolt through the receiver (also no site has ever questioned how I'm locked to semi only, just chrono'd me at the weight I'm using and trusted me (I shoot 0.40g and have never cheated chrono in any way)).

Be interesting to see what you get, I've done several nozzle tests recently, with o-rings against those without, good seal nozzle at retracted and extended point vs one with no seal and the fps was always the same.  A lot of other variables of course and no 2 setups are ever the same.  Let us know how you get on.

@ak2m4 In the past I did try an o-ring nozzle in one of my DE M900's, with absolutely no difference at all (I think it was one of your XT nozzles).

However the Maxx Model M4A-PRO + their own 21.25 nozzle with o-ring did give me extra FPS, so I'm wondering if the nozzle is just mating up perfectly with the bucking in the hop unit and improving the air seal?

 Finally got round to testing the gun out. The guns now shooting 1.09J so a slight increase over what it was new and I've gained 0.14J from my last game day, so I'm happy with that.

If any DE M900 owners are interested I bought a couple of these as I was off work last week relaxing at home...

https://www.ak2m4.co.uk/internal-parts/motors-parts/xt-high-torque-motor-22tpa-long-fan

... and wanted to see how they'd effect things (one for me to play around with and another for my son's upgraded G&G Firehawk that has as stock an M130 spring).

DE have said to me that the stock Chaoli motor they use is 19,000 RPM, but not at what voltage of battery and what its TPA is, so I put one into my M904E which is currently running an M105 spring. Just turning the stock Chaoli and XT motors pinions with your fingers there's a massive difference, with the Chaoli turning very easily and the XT requiring substantially more force with its strong magnets.

RPS only slightly improved, I wasn't really interested in that though, but the trigger response on semi is substantially better with all that torque available (and I run a Maxx Model Advanced Trigger so have set a very short trigger pull as well). I play most of the time at a semi only site so will definitely be getting my first shot off quicker and will be able to merrily spam the trigger if I'm in that sort of mood.

For a while I was tempted by a 27,000 RPM Warhead Base motor, but with the trigger response now so good I'm not sure if it's worth it (plus I'd be worried about PME and I don't want to play around with gear ratios to be honest).

For only £33.50 it's a cracking upgrade

@Fatboy40 thanks for the feedback, so far I've been very happy with the performance and reliability of the XT 22TPA.  I was getting around 5% failures with the ZCI and Rocket motors, very annoying.  These XT motors with their top fan seem to keep the temperature down, so less damage to the wiring and commutator over time. 

The stock Chaoli used ferrite magnets I'm guessing.  TPA is a term that isn't generally used by motor factories, and I guess doesn't mean too much to them without knowing the thickness of the wiring.  RPM and Torque seem to be what they go by.  

What battery are you using with the DE?

 

[Fatboy40]

What battery are you using with the DE?

11.1v 3,000 mAh Li-Io's from either Titan or Valken.

 

[Stevobeavo]

I have one of the XT 22 in a DMR build I'm doing at the moment. Had it for over a year but only just started using it. I'm surprised by how snappy it is compared to the specna edge 'upgraded' motor.

So.... I may have been bitten by the honey badger... I love mine so much that I've downloaded the handbook from Q in the US to get the colours right when I paint/cerakote it... ?

Then, being the daft bugger I am, I emailed Q to ask if u could copy the Q and the "live free or die" logos. 

Kevin from Q (the owner!) emailed me back with hi res pictures of it and told me if I was ever in the neighbourhood to come over and have a blast with the real 300 blackout... What a gent!!

Admit it, you've started looking up the price of airline tickets, haven't you? 

(I would!)

 

[xbaems]

I ve seen many guys here say that they get much fps from springs like m120, i ve seen someone say that they got aroung 465 with 0.2bbs, limits in my country are pretty generous(ocb 1.88j for full auto and 2.32 for semi auto) anyone using m130 spring that would care enough to say their fps? I have all stock parts. Many thanks!

Edit: for anyone curious, limits for bolt action are 3.34j

I did a thing....??

Well shitballs....

Just ordered the M904G for the weekend along with a cheeky little red dot to go with a magnifier I picked up on the cheap the other weekend.

Hopefully SWMBO won't notice gun number 12 sneaking its merry way into the family.  Jesus, the boy and I have only been doing this a little over a year.

I blame you lot.

Correction....

Gun 13...

Hopefully won't be unlucky.

 

[RostokMcSpoons]

Obviously I think DEs are great, and I've had hankerings for a 904 as a lightweight backup gun, but even I have managed to resist that temptation (so far), so why did you feel the need?

 

[Dan Robinson]

so why did you feel the need?

Still not had a chance to get my Specna sent off to repair, so am stuck running DMR and pistols.  So I needed a back up AEG.  Also had a hankering for burst fire mode for some reason I can't quite think of.

Didn't want to spend a lot either as I have a lot of house related out goings to come in the next 6 months.

Considering using it as a secondary with my M7, which should be out for the weekend too (yay); although the 904 is longer than my Specna when collapsed.  

The boy has his long guns, but I don't like the running around game style with them.

I am hoping that the batteries we have will fit in the stock, but I'm not adverse to a bit of gaffer tape if needed.  I tried the links to the Thingiverse, from @mightyjebus, but the links are not working now.

The 11.1v compatibility was an interest as well for CQB, assuming it lifts the ROF a little.

So basically, it ticked a lot of boxes and was in budget.  Otherwise, I would be looking at an L85A3 or a project - which I don't have the time or money for.

 

[RostokMcSpoons]

Just be careful if you try to sling the gun over your shoulder when you run around with the sniper, I managed to pop a mag out as it bumped around, I was very lucky someone found it and handed it in

 

[Dan Robinson]

Not planning on running too much with the M7 - the fecking grip might fall off again let alone the sodding mags ??????

Right off to bed - have to be in Wembley and sensible for 8am tomorrow.

Hi All.

After reading all this, I’ve now got an M509G in the arsenal and am waiting for an M509L to come into stock somewhere!

In the mean time and for reference, once the small un-windy hand guard bolt thing has been removed and the hand guard itself pulled off, other hand guards fit!

The one from my SSR4 goes straight on ?

Will look at the barrel nut and inner barrels soon and report back on what I find. 
 

Pat.

Looking good, @Point Two Balls  ... hope you enjoy your new gnu as much as I've enjoyed my DE so far.
You seem to have got your model number a bit awry though, unless there's some new models out there... looks like the 904G ...?

 

[Point Two Balls]

Oops - yep - numbers all wrong. Meant M904G and M904L.

 

[RostokMcSpoons]

Can I suggest you consider the M908 series if you're thinking of another DE...?
I know the 904G tends to be the cheapest in the range (£150 at Patrolbase today), my recent look at others that are available suggests the prices have squashed up together, so a 904L might well be around the £180-190 mark.

For a little bit more (£230), you could have this...

The 908A has the long barrel like the 904L, but it's got two potentially worthwhile features:
 

1) It's all metal.  Ok, if you want the lightest weight, then polymer is the way to go.  I like the feel of steel (or pot metal, or aluminium) though, and it's not that much heavier.

2) The PTS-style stock.  Plenty of space for bigger batteries - nunchuck style for instance.  I upgraded my 906 to a PTS stock and it allowed me to fit a chunky Titan 11.1 3000mAh battery in there, saving a lot of fiddling around that I had with smaller batteries in the DE stock.

You might not consider either of these things important - but just thought you might be interested.
 

 

[Point Two Balls]

Thanks for the info - but it is the Polymer that I want and I much prefer the PDW stock.

I love the front half of my SSR4 and the receiver, pistol grip and the sound of the M904G.

A new polymer hand guard from Novvy is only 15 euros and I planned to fit a new barrel and bucking to the M904G anyway - if I add the Novvy barrel and a cheap 2" barrel extension, I have everything I need in a gun... for now.

And for a bit more reference if anyone needs to know in future (google pointed me to this thread when I was making my enquiries), the outer barrel and barrel nut threads of the M904G are standard so easy to swap in the future if needed.

The M904G barrel nut is a bit weird though (in a good way as it helps support the handrail) and needs a pin spanner to removed it.

The second pic has the nut from the SSR4 screwed onto it for reference.

Pat.
