Brushless airsoft guns?
 

Is this even possible? I'm thinking of upgrading a airsoft AEG to brushless/lipo power somehow. Can this be done? I was thinking of using a servo tester with my trigger mounted to it to activate the motor. I was also wondering what size motor these guns use. Looks fairly small, here's a link to one:

Thanks y'all

This would be very cool considering it would be possible (if you so wanted) to very your ROF (rate of fire).

My friends are into airsoft guns and I'm their source of battery knowledge. I charge their lipo's for them since they don't want to spend money on a charger.

But anyway, you could make it so that at full throttle you obviously have maximum firing speed but you can let off on the trigger and have it slow down the firing rate to conserve ammo or something. Also, I would suggest you make it so that the motor brakes when the trigger is released.

Yep. Main problem is finding out what size the motor is.

my friends and me have been into the hobby for bout 5 years now and we upgrade our own guns.
to tell you the truth, theres no need for a brushless motor. these motors have plenty speed and torque as it is.
and i never ever had to replace the brushes and its still as powerful as day one. only thing you needa change is the spring overtime.
but if you want more speed and power, its not the motor you want to replace. you need stiffer spring, metal piston, metal gears, etc...i can give you a list if you want.
and if your serious about airsoft, dont buy that brand you linked.
the only brand airsoft gun you should get is Tokyo Marui and then Classic Army.
let me know if you got further questions....oh and i got plenty websites to order from...mainly from hong kong, but i think i got some sites from united states but its a lil more expensive.
heck, i got a mp5 i would think of selling if your interested. upgraded and ready to rock shoots a very high rate of fire too and super accurate!

My brother is into airsoft guns (his are more like airsoft cannons!) and I've been wanting to rig up a BL setup so he could pull a massive spring and get even an even more insane rate of fire. I don't remember the motor he said he had but it was about $90 and on a 9.6v it shoots faster than most of his magazines can feed and drains ammo too fast. If you could slow it down the added efficiency (longer battery life) would be nice but BL is so much more expensive than brushed because it requires an external commutator (ESC, mechanical commutation is possible but highly inefficient and wouldn't work too well especially in this instance).

just do what I did, take a potato cannon, fill it with about 250 bbs, and just fire it in the general direction of your target! It'll rain BB's for a good 30 seconds when shot upwards

Hey thanks guys. I was thinking just a cheap hobbycity plane esc, servo tester, and small inrunner. Anyone know what shaft diameter they use for the motors on the guns?

Seriously not worth the effort- you'll destroy the internals of the gun, then have to spend 10 times as much upgrading it. Heck, you can destroy the internals just by going to lipo from nicads/ nimhs. There has been talk on Arnies Airsoft about lipo and BL powered guns, but in all seriousness, just upgrading the stock motors to a better version (think 540 silver can to 19t tuning motor) gives you a higher Rof and power output than you could possibly need, not to mention if you go too fast it causes issues with the gun feeding ammo quick enough = mushed ammo inisde the chamber, not fun to clean out.

This is one of those times where BL is not a good upgrade...

yup the internals would break into pieces. anything above 375fps, your gonna have to upgrade the inside. even the mech box will crack (thats where all the internals are stored) and thats made of metal, but they use cheap pot metal. a good mech box runs about $200. and thats not including the piston, spring, motor, cylinder, etc.
i spent about 2k on my MAIN GUN and thats not even going brushless. if you still have any technical questions. this is my favorite forum ....Airsoftforum.com....its like RCM but airsoft.

You'll be going through millions of BB's, you'll have to make a magazine out of a cardboard box, it'd be spitting BB's out so fast, it won't even be a BB dotted line...

Destroy internals, just not worth it IMHO.

Besides if your that into airsoft and you want a faster rof and more power just get something like one of these http://www.airsoftstation.com/echo-1...rifle-aeg.html

Nothing against airsoft, but real guns are much more fun... Especially if you have rich friends that can afford the "fully loaded" models...

375rpm is pretty poor on a real auto... I have inspected and toyed with roller delayed designs that can support upwards of 1500rpm, and that is rifle ammo... If you are into mechanical stuff, self loading weapons, especially belt fed locked chamber stuff is very interesting. Main reason I got into guns was to see how they worked. Some of the design is just plain genius.

Feed design on airsoft needs some work by the looks of it. I know paintball have the hoppers with the rotating feed disks, maybe something like that to arrange the bb's on an airsoft?

Yah, nothing beats real guns I agree... .303 British Enfields, 12ga and 20ga shotguns, and .45 cal pistols.... I love doing long distance shooting as well. at least 500yards away, with the Enfields of course.

But if you want to upgrade something, upgrade the battery, make it an A123 pack, great use for them, IMO.

A buddy of mine is working on his Mechanical Engineering degree and is working on an electro-magnet piston for airsoft guns. It'll eliminate the motor all-together, run on much less power, and will be extremely reliable :tongue:

Real guns >>>> toy guns. If less-lethal rounds (like beanbags) were cheaper we'd be playing with shotguns and maybe some body armor. Probably best for everyone that those things aren't cheap.

Err....

The thing about airsoft is ... its airsoft. You run around woods shooting at eachother, re-ennacting military scenareos (sp) and what not, whilst having a great time and meeting new people (if you go to the big team events and organized events). You cant really do that with real guns- thats what joining ther army is for, if you wanna run around and shoot at people; you dont respawn at the end of the match though if you get hit...

When it comes to target shooting though, then obviously I'd take real guns any day, though over this side of the pond I have to make do with my spiffy 12 ft/lb airrifle.

Its all good....

Well the idea has been abandoned as far as BL goes. Just today though I picked up a genuine tokyo marui mp5 for $90 with 7 clips, tactical lazer, tactical pressure activated flashlight, a battery and some BBs. Only shoots ~300fps, but the rof is good so I'm happy.

Picked it up already!?

Jeez.

Yep. It's a beast.

good buy. im glad you went with tokyo marui. anything other brand besides that and Classic army would have been a bad buy.
now go get you some Airsoft elite BB's .20g and you'll notice better groupings in your shots.
if you cant find those, look for ksc perfect bb's. in .20 g

i would at least upgrade the spring...put in a systema 120 or guarder 110. and it up your fps to about 400fps. its a cheap and simple upgrade.
