[battery vs motor decision]

What do you mean by "whining post cycle"?

It's not a good idea running a normal AEG on 11.1V because it will burn the contacts on the trigger switch. Make a simple MOSFET circuit that protects it, then it should be fine.

However if there are weird sounds when using it, there is probably something else is going on with the gun. High torque motor will only make it cycle faster and possibly double feeding, plus since it will draw much higher current, it will burn the switch much faster.

All in all, if it is a backup gun, you might be better off with a 7.4V lipo and not modifying the gun itself.

[Blank Firing Gun Kills]

Don't worry. In the UK half the players would faint hearing the first blank shot and the next day youtube would be full of videos of "REAL STEEL GUN SHOT MADE MY EAR BLEED".

[Rifle choice]

For years you will perform the same with a good working £100 AEG and a good working £400 one. If all the skills and gear are sorted, that's when you will be able to use the quality difference, if at all.

 

Ranges: reliably hitting targets at 50m is good for an AEG, 60m is very good. DMR-ing adds a few meters, +10 maybe. Tuned 500fps sniper rifles hit in the 70-90m range.

[Ballistics and how less power is more energy delivery.]

Advanced topics:

Heavier BBs will fly further than light ones if fired with the same energy. We are talking about normal BB weights and site legal energies.

Heavier BBs fired from the same gun will have more energy than lighter ones if the gas volume is matching the barrel for the heavy one.

BB fired with hop on will have way more energy than with hop off. In VSR style guns.

 

Meaning there's so much more than simple ballistics affecting an airsoft gun that it looks like at first. It's a very very complex system. Tests and observations get us further than speculating on a subset of physics laws in effect.

[Sniper rang? Really!]

But ballistic calculators don't incorporate backspin, because real steel bullets don't do that. They can not give you anything remotely accurate results for airsoft. It affects range and trajectory for BBs more than anything else.

This is ballistic:

This is with backspin (Magnus effect)

You are correct about weights, etc, but that's not the whole picture.

[Ballistics and how less power is more energy delivery.]

Those seem to be some soft metal slugs. My guess is that it works like a bullet, and expands into the rifling. The more pressure it has behind it, the more it expands, creating more friction and slowing down the slug.

Airsoft BBs have backspin that greatly affect the trajectory.

Most of them at least. There's an indoor sniping thing in Japan where they have very precisely built rifles with no hopup to shoot coin sized targets in close, 10-20m ranges. No hopup because that makes them less accurate.

Hmm, do we have research on that?

Only my empirical evidence, but I will try to look it up, because I've read it somewhere first. And it changed my life.

you will want a 70 or 80 degree rubber and use the heaviest BBs possible

Bucking hardness is for the fps measured with the weight used. Not with what the fps would be with 0.20g.

[Sniper rang? Really!]

If you are using heavy BBs (which you should), use a hardness 50-60 houpup rubber. They are the best for about 330-350 fps which you should aim for. If you use light bbs (you shouldn't), so the fps is around 450, then use a hard rubber. So it is not x fps measured with 0.20g, but the actual fps you measure with the weight you use.

[Selling airsoft internal and external parts]

You can sell the parts. Even if they make up a complete gun, because manufacturing a RIF is an offence when they want to assemble them. And that's on them, not on you.

[Discharging AEP Lipos?]

I had a few lipos go puffy because I stored them fully charged.

[Disabled and taking part + Moans from the past]

Sniping is not easy on the legs.

[Futuristic Concept Airsoft Pistol]

Nice concept.

The trigger guard looks very small though.

[Hoping to return to airsoft and looking for sites within ten miles of High Wycombe]

There's Reforger at Watford that might be within range. Nice woodland site.

[V3 motor too loose]

The bottom of the motor cage is what preventing it from turning around (and the grip too). If it is lower and sits in its place, it won't be able to do it.

[V3 motor too loose]

It's too high. Shim the bevel gear lower so the motor can sit further back.

[General aeg range]

My experience:

340 FPS on 0.20, with correct heavy weight BBs, reliably hits around where you aim (not lobbing): 50m good, 60m great.

And it doesn't leak now?

[Best Bolt Action Rifles]

The best one as per my experience is my Striker. No, you can't have it.

Dear Matt,

It's not too much to ask for.

[g&g mosfet burnt out]

Is the battery that old too? Mosfets don't like low voltages. They burn. However, I don't know how exactly and how that affects the fuse. My non educated guess is that the low voltage doesn't open the mosfet enough, resulting a kind of short circuit, which then blows the fuse.

TLDR: try with a good, fresh battery.

I never understood printing 100%.

[Sceptical about range of rifle claimed]

70m sure, 80 is rare. He's saying 70-80, which means max 70.

VSR rubber won't fit an AEG. I guess he means the maple leaf AEG rubbers, which are the same colours and names as the vsr rubbers. But if it's s-hopped then it doesn't matter.

[Sniper and DMR Single and Double Band.]

At such a site I could play one game with my purpose built sub 350 sniper rifle and it immediately confused the players. The next game it was MED for any boltie.

 

Which is weird since a dmr m4 with MED vs a normal m4 is somehow perfetly acceptable...

[world airsoft- what do others do differently]

In Hungary, my country of origin, they have

• 400 fps on normal stuff
• 500 fps DMR, 20m MED, single shot
• 600 fps boltie, 20m MED

The engagements aren't any different than here, just everything happen about 5 meters farther.

The game culture is very different. Sites are much bigger, it's always working in squads with objectives, almost always there's a side commander coordinating the squads, there are dedicated medics and most importantly at least 6 hours game days with no breaks.
