I have a question about motor seating. Can it affect velocity? I don't see how it could, but this is what I observed tonight and want to run it by you guys. I'm a noob and out to learn as much as possible so that one day, I don't have to bug you guys with this stuff.
Tonight I took out my newly upgraded C8 for a little target practice in my house. I bought a new target to replace the one I destroyed with this gun on the weekend, and set it up at the end of a long hallway in my house. From my firing position, I was about 30 feet from the target. That extra distance was enough so I wasn't blasting right through the target this time
. The BBs were hitting very hard, but didn't go through.
I shot off a couple of 68 rnd mags in mixed auto and semi-auto and noticed the motor's sound seemed louder and more high pitched than before. I assumed (and correctly so) that it was because my motor was too low. So I started to raise and lower it until it ran as quiet as possible.
I loaded up a 130 round mag, and started firing again. While I can't comfirm this, the sound of the BBs impacting the target
seemed harder then before I adjusted the motor. The way I understand it, The motor drives the gears, and the sector gear drives the piston and tappet plate. When the gear releases the piston, the spring releasing is what creates the compression and in turn, determines the velocity of the BB. The motor shouldn't have anything to do with it the release cycle. Yet, the impact sounds appeared to be louder than before the motor adjustment.
Now, the impacts may also have just sounded louder because I no longer had the motor whining right by my ear. Without the extra high pitch whining noise from the motor near my ear I might have been able to hear the impact sounds more clearly.
So, motor seating affect velocity, or was I mistaken thinking it shot harder?
As a side note, I also realized that those Modify gears have made my gearbox a lot more silent than before. The new spring has definitely made the sound of the shots a lot louder (in a good way), but the gearbox itself is very quiet in comparison. When stock, this gun's internals used to be a lot louder than my M15. Now with the motor correctly seated and the new gears, you can hardly hear the gears and motor over the sound of the shots. I'm quite impressed with these gears and I may just get a set of high speed Modify gears for my JG 416 when I receive it.
