I'm looking to upgrade my combat machine into a 'DMR' setup. I put it in quotes because It's not going tp be semi auto only, but rather a long range gun. One of the things I'm interested in is having a really quick trigger response. I'm planing to leave the spring alone (shooting about 360 with my TBB), but I would like a quicker trigger response. What's the best way to achieve this? I"ve been doing a small amount of research, and I know that the most important parts are the gears, motor, and wiring. (If I'm wrong here it wouldn't surprise me). Assume I'm using a 9.6v so I don't have to deal with mosfets I've been looking into the following set up: Low resistance wiring a new motor, probably a JG blue (open to suggestions) 16:1 gears Is there anything else i should add or anything i should change? anything you'd recommend? thanks guys

I'm pretty sure using a higher voltage battery would also help.

yeah, I know. I'll edit my original post to mention that.

FET and an 11.1 will certainly help. You could get a precocking fet like the BTC spectre.
Otherwise just get as high speed gears as possible coupled with the most high torque motor. I ran a JG blue with 16:1s and the response was very good, but recently I decided I wanted more, so I made a higher torque motor and got riot 10:1 gears. It's pretty awesome now, but I've also found that trigger pull has a lot to do with it. The pull on AEGs is quite long, so the next thing on my list is to try shortening it a good bit, not to the point of making a hair trigger.

The JG blue actually has more torque than the SHS. AFIK the JG blue has more torque than any other motor on the market. Torque is dependent on magnet strength how many winds/turns of wire there are on the armature (TPA). The more winds, the more torque and less speed, the less winds the less torque and more speed. The JG blue has 22 TPA and the SHS has 16. I took an SHS neo magnet can and put in a dboys/chaoli armature that has either 28 or 32 TPA (I think I wrecked this arm, so I will soon take it apart and count). This type of motor is nicknamed the frankentorque. Needless to say it has an incredible amount of torque, but they are extremely slow unless you combine them with really high speed gears. I have no idea what your ROF/Response will be like with a 9.6, but you can do the math with the equation I mentioned in gimpalong's thread, I'd guess it will be a little bit lower than what the equation turns out, seeing as the equation is meant to be used with lipos. I'd say the first thing to do would be get an 11.1 and a mosfet. Lipos are literally like $10 and mosfets are only about $20. Any of the FETs sold here are good. forums.airsoftmechanics.com/index.php?board=20.0I am particularly interested in the ones sold by nukeduster since they seem even more compact than the one I have, which is made by jonezy. I like the fact that nukeduster's has both wires running through the fet. IMO it is helpful for routing. And yes, the new SHS 13:1s would be a good choice.

Alright, I'll look into those mosfets and lipo's. thanks for your help.

No problem. I should mention that going to the lower ratio gears will give you a higher ROF as you should expect. Just make sure you have the gearbox adequately protected to withstand it. This should include AoE adjustment via sorbo, preferably radiusing the gearbox cylinder windows, and taking precautions against premature engagement.

alright. I'm actually looking to run this in semi auto mostly, but I'll at the very least pick up a sorbo pad.
