Speed questions

[Stache]

Hi ya'll, I'm going for a high speed and quiet gb set up. I'm going to use a high speed motor with 100:300 high torque gears with a 300 fps spring and an Aim top heck-fire high speed piston. Does anyone have any idea what the rof/ trigger response would be like? Thank you in advance.

It may help to know what type of battery you plan on using as well, you will get very different results from a 9.6 volt and a 11.1 volt from my experience

I'll be using a 11.1v

It is my understanding that you will get a better trigger response from a super high torque motor and high speed gears. ( like 13:1). The reason being that most high speed motors dont have enough torque to get up to max speed very quickly there for it takes a little bit of extra time to start putting out a high rate of fire, you will get a overall higher rate of fire with high speed motor but a slower trigger response compared to what I listed above.

I have a gun that I shoot in semi only with a high torque motor and 13:1 gears with a spring pushing about 300 fps. If I go full auto I get 33 RPS (11.1 battery, not the best battery though) ( I dont go full auto because people dont like getting shot 20+ times and Im not a dick like that either). The trigger response is very quick (3 hundredths of a second).

hope the info helps.

Not that I'm disputing your claim but how did you measure your trigger response?

[Kjones]

1 second divided by 33 rounds per second. = .03 = 3 hundredths of a second.

This helps a lot, thank you very much!

That's not an accurate way of testing. You're measuring cycle rate. That's not taking into account the amount of time it takes for the gears to spool up from a stop. Imagine using that method on a high speed motor with high speed gears. Sure your ROF might be 50 RPS but it takes time to build up to that speed.

If you want a 300fps high speed setup, I would recommend:
-balanced motor(16-18 TPA Neomagnet)
It will be responsive enough, especially with low ratio gears, and offer great ROF with minimal to no spin up time.
-13:1 or even 12:1 gears, SHS has them for approx $20
-m120 spring, and short stroke until desired fps(estimating 3-4 teeth) you will need the sheer strength of the spring to keep up with returning the piston for the higher ROF you want. Possibly a chopped M130 and a tooth ss'd, all depends on your barrel length/volume you need.
-AOE corrected perfectly with sorbo. 40d sorbo with neoprene protective pad
-prefect shimming, greased, etc
-Swiss cheesed metal tooth piston. And once you find your desired FPS, remove the unneeded teeth on the piston as well. To keep up with the speed and prevent PME, you'll need as light of a piston as possible, and I'm sure you'll appreciate the durability.
-low resistance wiring w/MOSFET w/ deans
-bearings will help inch out just a little bit more. Probably not very noticeable, but it will reduce resistance.

The thing with 100:300 gears, is that it will be very effecient, as oppose to 18:1 or stock, but they are usually used with torque setups that usually pull a lot of amps. The torque gears allow longer battery life/more shots on the stressful setup.

But that's just what I would do for what you are aiming to achieve.

I stand with kjones on this, in my personal rifle I use Zci 13:1 gears, a jg blue and an 11.1 Lipo and the trigger response if pronominal

Pronominal? *facepalm*
