if you want more consistent shots you should look into mosfet switches. You can get your timing and piston strokes to nearly the same volume of air. This will make your FPS similar and easier to predict your shots. Anymore than this and you'll want to look into a pre-cocking mosfet which will cause your AEG to pre-cock your piston before you pull trigger, like a psg1. Your spring wont last as long (just consider them another wear part, besides you'll wont need to replace your piston too much) but than you'll also have much less vibration and noise while shooting. The guys at airsoft mechanics are developing some switches for this and should be around $50US.

Did I read you correctly, are you going to be shooting at 300FPS?

Also, if you are looking at consistency, my setup was shooting 399, 407, 400 on semi at the last game I went to.

Draganta · November 13th, 2007, 02:07

No i am looking to shoot anywhere from 350-400 FPS (our field limits are 400)

im not looking for the hardest shooting gun... again i want it to be very very consistent... id rather my gun shoot 350 +-2fps.... rather then it shooting at 390 +- 10fps

my skill level is not extremley high by any means but i am a super fast learner... but id find it rather difficult if i have my gun shooting completely different every time i squeeze the trigger...

styrak are you using a tightbore on your setup?

Styrak · November 13th, 2007, 02:25

Nope, I'm not. But I thought of putting one in. Also, does 8-10 FPS (4-5 +-) matter?

Draganta · November 13th, 2007, 02:46

i was just being general in terms of what i want... 10 isnt a hard number... just the idea of having the gun shoot the same consistently.

Styrak · November 13th, 2007, 02:48

Well you apparently don't think my gun's numbers are consistent. And I know you didn't want 400 FPS. However, any good gun/upgrades will have consistent numbers, so it doesn't really matter, and given that you have an AUG as well, just getting a good quality spring (Systema, Prometheus, etc) will give you consistent numbers, I'm thinking.

I'm not quite sure if I understand how mosfet switches would accomplish that, can you explain a little more? I was under the impression that the piston stroke provides nearly the same volume of air with each shot because the sector gear is teethed to alway release the compressed piston at the same point, and that gear timing is for the most part a myth.

active braking can make a difference in timing. Normal AEGs have piston strokes that do not travel the same distance. The consistency in FPS might be more obvious in AEGs with type 0 cylinders.

http://extreme-fire.com/SW-SvsSW-AB.avi

The video has both regular and active breaking. the first portion, without AB and the last bit is with AB. Notice the white piston as its travel changes. Its a little random but with AB it stops at the cylinder head every time (notice the air nozzle too). Also notice the speed picks up too. AB is designed to prevent over spinning gears in high FPS and ROF AEGs but it also works wonders in semi auto only setups.

The variations in piston and gear travel can promote excess vibrations, movement and fluctuations in FPS. The AEG doesn't seal the same way every shot and the misalignments cause leaks.

The volume of air in the cylinder doesn't change. (sorry for any confusion) The FPS generated by moving parts become more precise and more consistent. The FPS becomes more consistent as a result. Pre-cocking is were its at through, this removes almost all the moving parts before you fire.

The pre-cocking mosfets are not out yet but they too will have AB and will force the piston to pre-cock prier to the trigger pull. This will cause your AEGs to shoot like a springer but still cock itself.

With computer controlled AEG Mosfet systems coming out, software will take over the AEGs funtions and power will be distributed for durations and amounts based on the comand to perform desired tasks.

Whats your guys feelings on the hurricane tune up kits? it seems to have most of what you guys are mentioning for around 80-100 dollars

Draganta · November 18th, 2007, 05:32

any ideas?

mateba · November 19th, 2007, 13:20

I don't know much about them but the Guarder FTKs are around that price range for a 400FPS upgrade. I imagine it would be a little cheaper if you wanted a lower rated spring. Illusion might have personal experience with one.
sorry,

Draganta · November 22nd, 2007, 00:08

FTK?

mcguyver · November 22nd, 2007, 00:11

FTK = Full Tune-up Kit. Usually includes gears, bushings, cylinder, head set, piston and sometimes a switch, springs, etc.

Draganta · November 23rd, 2007, 21:20

The tune up kits seem really good bang for your buck... any one have any experience with them?

mateba · November 24th, 2007, 13:23

not personally, but I don't see any harm in defaulting on a SystemA FTK. I have heard negative things about the guarder infinite torque gears, but other than that I like the products they sell. A regional store, Airsoft Atalanta, will choose only guarder gears (unless specified otherwise) for internal repair but i dont know if they use the infinite torque gears. hope it helps.
