We've all been there! Just FYI, they're not as bad as they used to be but if you use a lot of AB the carbon build up in the motor can make the Aster (although more prevalent with the Titan) lose the motor again. They tend to prefer using higher TPA motors.

Two questions - did you re-shim it and what sort of motor is it? Initial impressions are that the motor connector might be damaged or loose, so check that.

Good point, well presented. Does it do it with a 7.4v battery?

When you shimmed the gearbox, did you make sure that the sector gear cam is still reliably being seen by the Aster sensor? It may be a bit borderline.

What have you set up on the Aster? Is there precocking on semi?

Good bot!

I've got a couple like that, they're clearly made of assembled parts but just refuse to come apart.

According to this the end cap should screw off. You may just have to apply some heat to the tube or just y'know....brute force. https://imgur.com/a/iITkH

As has been mentioned above, get in touch with them directly https://www.eshop-aresairsoft.com/index.php?route=information/contact They've always been very helpful when I've bought stuff direct!

I use them in my LMG for the "lots to the everywhere" approach!

No mention of all the money he made from horse jizz then?

So why did you change it? It's probably more to do with the specifics of the barrel and hop rubber than anything else. Joules are joules, FPS is FPS.

Been listening to a lot of angry young men recently...

Ftfy.

Bit of both. In the UK the extremes of temperature aren't actually that extreme so much like you I've had no need to change rubbers purely because of environmental issues but I have seen a couple of my guns that perform poorly first thing on a winters day after having been packed in the car overnight on account of the rubber stiffening up in the cold. I'd personally say that there's FAR more difference in personal preference as far as the UK goes. If you drastically change the power of the gun or the weight of the BBs then you'll probably see more of a difference with grades of rubber than just the difference of a few degrees between an average winter and summer here (climate change notwithstanding of course) but even then it may just be down to longevity. The very anecdotal nature of airsoft "upgrades" is a problem so I (much like yourself) would love to see an actual, evidence based test much like the AATV style of video that does a back to back of the same three rubbers in the same gun on the same day and then repeated in deep midwinter and the height of summer to see just how much variation there actually is. Of course, as soon as you take the results and apply them to your own gun it all goes out the window (at least to some degree) because your gun ISN'T the gun the test was done with (even if it's the same model and manufacturer).

Absolutely correct but the discussion was about comparing three different grades of the same make and type of hop rubber in the same gun on the same day to see how much difference the hardness of the rubber itself actually makes.

The Krytac P90 is has both an electronic fire control unit and a MOSFET. The Perun P90 does not fit in a Krytac P90 (ie not a drop in fit but could probably be fettled in). Also - to address the MOSFET/ETU thing - a MOSFET is strictly just a transistor, not a chip. Unfortunately, much like Hoover, MOSFET has become an accepted term meaning some kind of electronic device fitted to an airsoft gun. Perun's MOSFET is a MOSFET with additional components on a circuit board, the Krytac MOSFET is even more basic in that is just the transistor (so you can truly say that it's just a MOSFET). A "programmable MOSFET" is a massive misnomer, it's a MOSFET with a programmable controller attached which may or may not be an ETU as well (eg Warfet vs ASTER).

It's really not. You've basically captured the essence of how it works in what you've said! The different hardness of rubbers is akin to when Pirelli rock up to an F1 race weekend with a 3 out of 5 selection of tyres (rated as C1 to C5). On a given day at a particular track a race car will have a finite amount of grip on any one type of tyre so let's say that on this particular day with a track temperature of say 40C it's the C3 tyre that gives the best grip. For that same car at the same track with a lower track temperature then a softer tyre will be better (eg the C1) on a hotter day you'd need a harder rubber to get the same grip (eg C5) because the hotter conditions will make the rubber deform more for a given speed/turning force. The same is true for hop rubbers. On an average UK day a 60 degree rubber in a 350FPS gun firing a 0.28 bb will give good hop. In the same gun with the same power and same BBs in a winter game in Norway it won't give enough so you need a softer rubber. Likewise, take the same gun to a summer game in Florida and you'll need a harder rubber. The tricky part is accounting for the variables in the gun itself - spring rate consistency, gearbox stiction, air seal, the stability of the hop unit (flex in the arm, deformation of the tensioner etc) bore quality in the barrel, all of which will have an effect in the consistency of the results. All the "marketing" is different companies trying to resolve the variations because airsofters want something that is reliable and consistent. The reason why there IS no consistency is that every manufacturer works to their own tolerances and goals and airsofters by and large are too dumb/gullible to work that out so you end up with what started out as a perfectly reasonable standard gun "upgraded" with loads of shiny bits from different manufacturers, none of which actually work properly TOGETHER.

First things first - check that it's actually straight in the hop unit.

It's literally like any other launcher. The video actually says that the iron sights are useless at giving enough elevation to get any useful range but that the sight mount will which again, is no different than any other launcher.

OH YES IT IS!

Actually, Ron it's THREE cars welded together.

But that's just what a scammer WOULD say!

One of my buddies has one and I've had to work on it. Decent guns until they break and then there's a bunch of proprietary parts that make life a bit complicated. They only really like their own hop unit and the gearbox is shaped in such a way that they only really fit their gears (which isn't entirely an issue as they are pretty tough). Some programmable mosfets won't fit/work because of the way the gearbox is. The pistol grip can be a bit fragile so make sure not to screw it in too hard if you have to take it off, the PTS EPG is a very good replacement though.
