PostSubject: Believe it or not, I've hit a wall with speed   Thu May 13, 2010 5:12 pm

So I've been trying to see just how fast I could get the L85 to shoot while maintaining the 400 FPS line.

My results:



If the video doesn't work:
http://illiweb.com/fa/pbucket.gif

It shoots 36 rounds a second thanks to the following:

- G&P M120 motor
- 7mm Kanzen Ceramic Steel bearings
- Stock version 7 gears
- Obsessive shimming
- DUAL AB Mosfets
- Deans plugs (duh...)
- Unknown spring from my "box-o-springs"
- Sector Cam
- Matrix full metal tooth polycarb piston
- Bearing spring guide
- Guarder bearing piston head

Oh yeah... and a 14.8V lipo

So yeah, as you can see it's AWESOME!

Take into account, this gun is running a 550mm 6.01 barrel and had a FULL cylinder. This equates to slow cycle rate because there is no port to break the suction which is really what made this rate of fire so impressive. Give me an M4 or an Mp5 and this rate of fire would be MUCH "easier" to accomplish.

The problem... It shoots so fast that I have FINALLY encountered the mythical "barrel suck"

In other words, bb's are still in the barrel when the piston is pounding away. Where does it get it's air? From the barrel...

So when I lay on the trigger in full auto, I get this explosion of bb's that starts at about 150-200 feet and then quickly drops off to a range of about 50 feet as bb after bb is drawn back by the "barrel suck"

Another thing to note, 14.8 volts is not motor friendly. I'm on my SECOND G&P M120 motor since the first one burnt up from all the voltage and needs some serious work to get it back or just to be thrown away.

Now I'm back to my 11.1 volt 25 C (30 burst) and getting a measly 27-28 a second. :-/ I just put in an order for an 11.1 volt 35C (40 burst) battery that should get me something in the middle of the two batteries hopefully. I found that 33 a second works for the gun and feeds right. I got this before the addition of the second mosfet. The 14.8 is just too abusive on the motor though so it's going to have to be set aside and I'll have to see what I can get with higher and higher C rated 11.1's. I'd go with high speed gears but it uses version 7 gears

All in all, while you guys will never see it on the field (at this ROF), I had to share none the less. Worry not, you'll see my CQB M4 at mid 30's or higher VERY soon.

Great work master... I must ask though, what is the principle behind Dual Fets.. How does it work, and what does it do?


You have me addicted to Modding now.. I have 4 projects going right now, and they all involve your AB MOSFET, a Cheetah MOSFET, and short Stroking...

My ICS as seen in prev posted Vids is putting out 35rps at 300 FPS (Air Leak somewhere?) on an 11.1v Lipo 35C (Ebay for like $29).. Stock Ratio gears.. This is with Fireman AB FET installed... this is also on an AMP Hi Torque motor... So far the only prob is heat from the motor...

I took the above setup and replaced the FET with an Extreme Fire Cheetah (Wanted Burst Mode) and it was slightly slower on default settings, but with motor speed increase, it screams, but again, the Motor gets hot and the fuse in the FET trips..

*I think I have to work on my Shimming skills.

ICS M4 Pistol,. Short Stroked 2 teeth, Systema Turbo, Stock Gears (For now).. 11.1v 2200mah 25c Lipo (Ebay $19).. This setup will not turn over once the gun is assembled... Again, I think I shim just one shim too much on the Bevel Gear...

JG CQB Shorty M4.. This setup is going to attain its speed with standard ratio gears, and a G&P M120 with a guarder S90 Spring... I am just waiting on another Fireman FET and it will be done.. I have a prelim vid of it posted on youtube now..

Last but not least.. My daughters Echo 1 MP5.... Nothing done yet... But I want to build her a 340-350 fps speed demon built specifically for SOCOM... If I can give her an intimidating gun, I think she will play a little more aggressively.. We will see.. Looking for 30 RPS for this one... So all I need is a FET and a LIPO, maybe a hi speed Motor.

The 35c Rating on the Lipo's seems to make a huge difference in performance.. I see an 8rps difference going from the 25c to the 35c.. Which was totally unexpected.

Do you mean Hi RPS in general or Dual FET?



I will add my input... When I play with my hi rate of fire setups, I do not have to pull the trigger as much or for as long to get "hit" calls. Not because it hurts more, or the guys are scared of it, It is because they are far more noticeable when you are hit 30-40 times in 2 seconds. Not only do they feel them more, you can actually hear the hits as well. And I cannot lie, I like the attention it gets when I fire it for the first time. There is something about being able to do something not many people are doing. And doing it my way, because everyone reaches ROF goals differently.

About the onlything you could do is, switch to the M160 motor and go to HS gears and a shorter barrel.

Not that i would change anything.

In theory, the M160 motor has heavier wire windings to handle the extra voltage/amperage. It will spin too slow to get solidly in the 30's but the high speed gears should make up for it.
I would expect that the torque loss from the HS gears would easily be offset by the motor torque and acctually increase ROF.
I guess the only way to see if the M160 motor will handle the 14.8 LiPO is to try it.

Are you running a MOSFET on each lead. (+/_) to split the load?

Auto's recommendation is exactly why I run an AMP hi Torque instead of my Hi Speed Motors. Both my HS Motors run really hot with my Lipo's. The AMP doesnt even compare in regards to heat.

Actually, I just did the dual mosfets because along with the motor, the mosfet was getting hot under the 14.8 load. It was also a mosfet I'd had in the gun for about a year. Eventually, the heat built up so high that the mosfet casing itself cracked. Like I said, this mosfet has seen A LOT of abuse...

The dual mosfets were something I figured I'd test just to see what it did. They do not get anywhere near as hot. The motor on the other hand still did.

As for high speed gears, I need version 7 gears and high speed of these are not cheap. The only ones I've seen on airsoftgi.com were Prometheus (which are my favorite) but also carried a price tag of $100.00.

I'd be open to other brands but it's the version 7 aspect that I keep running into. I just grabbed a high speed set made by AIM that came with a full metal tooth piston that is going into an Mp5 I just got. The whole set (high speed gears and piston) were only $50.00. The piston itself is $20.00 alone so I felt it was a good deal. At least unless the gears end up being crap... So far on the "looks test" I'm very satisfied with them. They just look mean.

Auto, if you could get your hands on a set of high speed version 7 gears for a good price please let me know.

I may also be interested in that M160 motor but I'll wait and see how this battery does. I'm torn between the two since the M160 is more or less a knockoff of the Systema Magnum and in this same gun (where the Magnum used to be) the G&P M120 BLEW AWAY the Magnum on speed. For granted I'm running an M110-m120 spring so it makes sense... I figure with a heavier spring it would be quite the opposite.

CharleyNovember - I forgot to address your question

I do it because I can. It's sort of like people who mod Honda Civics to do 9 second 1/4 miles. It's not like they will really ever use all that power but once in a while it's fun to jump off the line when the light turns green so you can haul ass up to the speed limit. :-P

With the airsoft aspect, yeah, it's about showmanship to an extent. When I was walking back to staging at the TC airsoft game people would randomly blow bb's into the woods shooting at unsuspecting trees. I decided "me too" and shot a few rounds. Behind me all I could hear was "shit!" and "damn!" and "glad he's on my side". Then in staging I got approached my several people asking how I'd done it and a few guys who wanted me to do it to their guns. Not only does it stroke my ego (because you have to admit, everyone's ego needs to be stroked from time to time...) but it also drums up business. :-)

Fair enough on both responses. Everyone gets different things from the hobby who am I to question what aspects you enjoy. Edit to d...I think this is a cool idea with support weapons. Support weapons should lay down strings of solid plastic. When I get a new one maybe I should send it to you. Laughing

Fireman. You never did explain the install of the dual FET's.

Are they wired, one on each motor lead? One on positive and one on negetive?


On the topic of suppot weapons. I'm thingking of breaking doun my old DeWalt 18v drill motor and battery to try to build a SAW that will meet the 450 max FPS and lay down 35+ RPSP. The motor in thoes things have the capability to run at like 38000 RPM unloaded and I know its got torque.

Oh no, they are both wired in the same manner as one would be. I just have two. More or less, there are two sharing the load and it seems the heat also. I figure it gives two pipelines for the power to travel as well, sort of like with car audio when you don't have the space to run a heavy wire, two wires a gauge down will work the same.

With the 25C 11.1 I don't actually see an improvement. I saw it with the 14.8 where I went from 33 to 36 but with the 11.1 maybe the power is "low" enough that one mosfet does the job. For granted, the heat will still be lower which is always a good thing so far as mosfets are concerned.

so are we saying 36rof is the "sound barrier speed envelope" that cannot be broken without consequences?

No. Its just a glass ceiling you hit when balancing FPS with ROF. He could probably pick up a few RPS if he shortened the barrel to say 400mm but would loose a little FPS.

A lot of variables start to affect the consistancy, operation and efficiency of the gearbox when you start pushing 400 FPS into the 30+ RPS range.

He would probably gain a few RPS too if he switched the barrel to a 6.05 but he would loose accuracy in that aspect hes basically at the wall where the its one or the other.

What about putting in a capacitor to maintain a more consistent voltage or the two mosfets are already doing that?

the High discharge rate of the Lipo does that on its own. In all actuality I think CAPS are overrated in Airsoft. They still depend on the discharge rate of the battery. But my research into that subject is fairly fresh, so I may still be missing a point to them.. Hopefully Fireman or anyone else here has more experience and can shed more light.

I'm sure you've found this on your own, but they deserve a few plaudits. These guys have quite a bit of information and take everything from a much more thorough and scientific approach then most people doing airsoft. It seems like more work then it is worth, but it might be worth trying.

Little about adding caps yes they do make a slight difference but if if too much of a load goes through them they will explode I have been burned and cut by an exploding cap once requiring 5 stitches so there is no way I am putting a CAP that close to my face if you wanna do it by all means but its not a chance im willing to take.

I've researched about capacitors as well. My problem is NOT lacking power or speed. I have too much!

As for capacitors, I've just decided that they do not add enough to the gun to add another item that can break, melt, blow up, etc. That and nowhere really says WHICH capacitor to get. :-)

Shar - Not at all. It's just the ceiling of the gun itself with the cylinder and the barrel I have.

If I had a shorter barrel bb's would have more change to get out prior to being "sucked back"

If I had a cylinder that had a hole in it, air could be take from the hole rather than the barrel. Only problem is that for the barrel length I have, I really need to use a full cylinder or else I'd have FPS loss when the bb's were no longer being pushed out of the barrel but traveling on their own inertia and "slowing down" as they rubbed against the barrel.

If I used a barrel with a looser bore, there would be air that could be pulled around the bb. Using the 6.01 means that there is little space around the bb for air to move and thus, the bb is brought back too.

All in all, this gun is more for accuracy than spraying bb's so if 27-30 a second is the most I can get, so be it. I do not wish to downgrade any part of the gun in order to give me a higher ROF.

As for the Mp5 I'm making now, I'm going to go balls out and see just how far I can go.

Parts it will have:

G&P M120 motor
11.1 lipo
AIM high speed gears
AIM high speed full metal tooth polycarb piston
Prometheus 7mm bearings
Guarder ball bearing spring guide
Guarder Ball bearing piston head
Stock barrel (unless I get my hands on a 6.03 of correct length)
Stock spring (puts out 395 FPS right now)
AB Mosfet (of course...)

Based on my last M4 with longer barrel and standard gears getting 33 a second, I expect this Mp5 to be putting out higher with the high speed gears. Stay tuned for results! Hopefully I'll have it with me on Sunday.
