What's your rate of fire?

[LUTNIT]

Turbos are rated for up to M135 springs but I find if I go above an M110 my Magnum is faster. A magnum in my stock TM MP5k is giving around 20rps with the 8.4V stick, a turbo gives over 25rps in the same gun. Low springs, use a turbo.

Also put a turbo and a magnum motor against metal, the magnums have FAR stronger magnets in them than the turbos. Turbos are still stronger than say a stock TM but no where near the magnum.

marui m4 pdi 190%, 10.8batt ni-ca syst magnum. 28bb's/sec at 430fps.

Video of the 41 RPS gun or it didnt happen.

I have 3 AEG's i use.

My primary niceness gun.
runs on a 11,1 2000 mAh Elite LiPo with Super high speed CNC gears and super core piston, shortstroke is 5 teeth i use a SP160 spring from guarder. This gives me.
ROF 32,4 per second / 1944 RPM. FPS is 415.

My power gun.
Currently runs CNC torque gearset, super core piston, extreme fire panther computer and a sp160 guarder spring, on 11,1 2000 mAh Elite lipo i get 22 RPS / 1320 RPM, and 525 FPS

My Close quarter gun.

Super high speed CNC gears and super core piston, shortstroke is 6 teeth i use a SP150 spring from guarder, and a Marui EG1000 motor and 12v 3000 mAh Elite NiMH battery. ROF is around 27 RPS 1620 RPM. FPS around 345.

I prefer using Jing gong hicaps since the feed excellently. during Milsim i use kingarms midcaps moddet for around 78 rounds capacity.

so do you guys like... walk the BBs ?

Would a picture of the Siegetek Concepts Cyclone Dual Sector Gear (left gear in pic), and a MP3 of the gun firing suffice for now? I was given these gears to review for the NJ Airsoft Association, and since I haven't released the review yet, I don't want to release the videos before I've finished the review.

I blew out several 7mm bearings in my Haynes box with a Guarder SP170 spring, so I'm waiting on 7mm bushings, and a MOSFET to continue the testing (have a Systema Magnum, and G&P M160 motor for the test as well). Trying to reach 35 RPS at 450 FPS (my field limit, and about the limit my TM Hi-Caps will feed BB's) without using a larger battery.

Always nice to have a little talk with a fellow highspeed High power enthusiast.

I have been testing Dannys CNC gears for the last 9 months and they are truly awesome. I have however found a weaknes with the reversal latch teeth and he is fixing that now.

However i do not see you getting 450 FPS with a 8 teeth short stroke modification. It is simply to much. remember our springs are progressive so not much power will come out of the gun. Further, i do not think that you will have enough Air in your cylinder for 450 fps when you have 8 teeth stroke.
If i use an unmodded SP160 spring on 5 teeth stroke with 285 mm PDI 601 barrel i get 425 FPS apporox so you need to add for instance 4 mm of spacers behind the spring.

The reason i want a video of the gun firing was that i thought, as you write your self, that you will have massive feedning problems at that ROF. Like you say around 35-37 RPS is the max brand new Marui og Jing gong magazines will feed at using 0,28 bbs. I have had one feed at 39 RPS with 0,25 BBs All from G&G brand. Further increase could perhaps be found with 0,20 BB's but thats just for show not for real gaming.

What kind og piston are you running in your setup? i use super core which have 8 metal teeth so shortstroke kan be done with a maximum of 7 teeth. where i use 5 and 6.


By the way if we are to make sound files i can make on with ROF 41.66 . but what use is thay when the gun wont feed :banghead:

As for your bearing problem. Use Modify or JBU 7mm Steel bushings they are the strongest i have found yet.
Personally i run Pro-win 8mm boxes in all my guns and 8mm kanzen bearings. I have however found some Full ceramich 4x8 mm bearings. but the thickness of our axles are only 3mm so Danny is finding a way for me to increase the axle size to 4mm. Those Full ceramic bearings are however 100$ a piece, YES thats 100 USD for 1 bearing and i need 6 :cry:

I'm using a Deepfire version 2 piston with titanium coated teeth for this setup. It's a little heavy, but I haven't stripped them yet (broken the piston body on the ver 1's, but never the teeth).

My TM hi-caps will feed about 100 BB's at 41 RPS before the gun starts skipping shots, so that's why I'm aiming for lower. I forgot to try my MAG mid-caps when the gun was built like that so I don't know if they'll feed higher.

The Guarder SP170 spring in this setup was doing 390 FPS with .2's, but I also fear I won't get any higher FPS than that withour going to extreme means. Feel free to PM me with any other questions.

HAHAHA NO! Semi and burst only. Trigger delay is nonexistent in my setup. People have asked me "is it a PTW" my reply is typically "no it cost me more than that :banghead:"

KWA M4- 11.1v lipo 2000mah 15C

Over 30 rps at 390 fps

[FOX_111]

P90tr 350fps with 9.6v: A whole lot of enought bps.
Snipers rifles: 1 shot per target. If missed, follow up shot are dependant, so no fixed rate of fire.

If the KWA is stock you are no where near 30 RPS.

I was thinking the same thing.

1120 RPM with S90 spring, G&P M120 motor, 8.4v 3600mAH

[TriChrome]

Got a new gun the other week, a stock G&P Defender and it shot 29 RPS at 325 FPS with .25's on a 11.1v 1100mah 15C Li-Poly. Extremely impressed with the ROF and the G&P M120 motor.

When I installed a 400 FPS spring, regreased and re-lubed everything it amazingly raised to 30 RPS.
