I checked again, the arl is in good shape and installed correctly. It's not too tight, just added a shim to get rid of any play

On second thought, maybe my cut off lever or nub on the sector gear may be slightly worn down, and replacing either or both would fix the issue

Its either the cut-off lever (cracked or broken), or you shimmed the sector gear too high. It could be your trigger system.... but i highly doubt it. Inspect the cut-off lever for and slight cracks or breaks. If its not broken double check check and make sure the sector gear isnt too high.

If this problem persists get a sector chip. You can get them for cents. Alot cheaper than a motor or MOSPHET....

Well the cut off lever looks okay, so Ill start with replacing the sector gear and reshimming it.

Do you mean sector gear delayers? If so I have some ordered and on the way already

sector clips only help with feeding issues due to very high rates of fire, they don't do anything for overcycling.
no such thing as a sector gear delayer

Yes and no. I have used them with lots of success when dealing with over-spin while using 7.4v lippo's, and works great. It will give the extra bit of friction needed to stop the gears (wont work using 11.1v). Using a sector clip WILL help with this over-spin especially because the gun is only over-cycling 1/4 cycle too much.
The overspin is probably because of a worn tappet plate, and a sector clip is cheaper than a tappet plate, which is why i suggested the clip over anything else.

What? You're going to have to elaborate on that one a bit for me, don't see it

That's not how you should be solving gun problems lol
The last thing you want to do is ADD friction to your setup.
If you're driving in the city, and your doing 65, it would be like keeping your foot on the gas at 65, and applying constant pressure on your brakes to reduce your speed to 60. You just don't do it.

I'm telling you, just upgrade your motor to one with stronger magnets, then it only adds resistance to the system when there is no power to the motor. Like braking AFTER you take your foot off the gas.

Very good analogy Frank. I didn't know how to reply without sounding like a douche

I'm getting really good at snarkist-analogism :)

LOL. then y is it recommended for high speed setups? It only adds friction to the cycle at the point where you need it (when its trying to stop) . The gun is ever cycling because of too much inertia. By adding a sector clip it will add stopping power because the sector gear and sector chip is in contact with the tappet plate for longer, adding more surface area. ITs not like its rubbing on gears or the side of the mech box... Its only coming into contact with the tappet plate (like its needs too).

Changing the motor is like changing the engine in your car when nothing is wrong with the engine.... Why not fix what the actual problem is.... and over-spin problem. And there is several ways to do this. A .50 cent plastic chip is more reasonable than a whole motor, and isnt replacing parts that is still good and nothing wrong with it (motor). There is no need to EVER replace a motor unless it is fried.

A sector chip does interact with the fin of the tapper plate longer than a smaller diameter post would...and in effect prolongs the portion of the firing cycle where the nozzle is retracted. The sole purpose of the nozzle being retracted is to allow a bb to feed up from a mag.

In high speed setups it's very possible for the nozzle to retract and return forward faster than the spring force of the mag can slip a bb into the feed path...so you'll get blanks.

By retracting the nozzle a bit earlier and letting it go forward a little later in the cycle enough time is created for a bb to get into the feed path

^That
Why fix what ain't broken? You don't have a feeding problem, so why use a solution that fixes a problem you don't have?
And it's not going to add enough friction to stop the gun from over cycling anyway, it doesn't add that much friction. I'm just saying you're looking at solving this problem the wrong way.

And there IS something wrong with the motor. The magnets aren't strong enough, and that's WHY it's over cycling.
Getting an SW-COMP with active braking will cost more than a new motor, and it'll just toast the current motor. You need a good motor to run an SW-COMP anyway.
Take the motor out of your gun, and spin it with your fingers, if it continues to spin, it has no stopping power. If you have trouble even turning it in the first place, it's a powerful motor AND it'll prevent over cycling.

I'm telling you, upgrading the motor will solve the problem 110%

A new motor prolly would fix the problem, just trying to eliminate any other possibilities. The gun never fired this way when I first got it, which is why I thought it was something I did inside the gearbox.

I'll update with new sector gear
