huh?

damn you, making me have to go do math...... so for 0.5 seconds of flight time, with a muzzle energy of 1j and hop set for ~20cm of rise above muzzle: a 0.2g bb will lose 0.002406j due to gravitational potential energy and 0.9j due to drag forces a 0.5g bb will lose 0.006015j due to gravitational potential energy and 0.58j due to drag force granted that's a very oversimplified calculation based on simply the flight time (ie not counting energy that would accelerate the bb upwards to get that 20cm of rise), but then the drag model is pretty over-simplified as well. however the point is it's a negligible amount compared to the primary force which is the conventional drag.

except that is very very literally what the magnus effect does to an airsoft bb.....

best i can make out that's probably a good analogy. seems they're switching to a cast rather than machined casing (shouldnt affect performance too much tbh) and moving to machine winding, which i don't know enough about motors to know how big an impact that'll have.

now there's a reference that's making me feel old now.... currently going through the outer worlds, been on my list for a while and picked it up on sale. not gotten too far into it yet but seems to be if fallout did a borderlands pre-prequel, which sits well with me having enjoyed fallout3/NV (haven't got around to 4 yet) and having sunk more time into the borderlands franchise than i'm willing to admit. doing my usual trick of a relaxed easy mode/relatively peaceful playthrough for the sake of enjoying the plot before messing around with specific builds/characters later on. tbh i'm just glad of any game that has more than 2 hours of plot to it in favor of the lazy development option of making a couple of big maps and adding a battle royale mode.

i wouldn't worry about upgrades in the short-term. the reason negative (at the time, he seems to have moved away from them) reccommends the warfet is because the customers he deals with (as a professional tech) generally aren't too into teching on their own guns, and a mosfet that can be hot-swapped between guns easily, or re-programmed very quickly in the field. the titan is a connoisseurs component, and a whilst it's a good bit of kit. but it's not something you want in your gun unless you have the background knowledge to set it up properly (which also means having the rest of the gearbox up to code), and deal with any issues that arise. what i would suggest as others have mentioned is to start off renting for a few games, see if you like the hobby enough to stick it out. once you have your ukara setup you'll be able to order a non 2-toned pew which is a bonus. i'd hang back from dropping too much money until the honeymoon is over, the reality is that generally speaking the supermegahighend pews aren't that much better than cheaper pews because at the end of the day there's only so much precision can be extracted from what boils down to an air powered smoothbore musket. it's also worth considering that you need more than just the gun, there's batteries, chargers, magazines, loaders, ammo, eyepro, good boots (seriously, good boots are worth the effort to figure out), camo (entirely optional but generally preferred for outdoors), load carrying gear, and any optics/flashlights/lasers/bipods/slings you might want to stick on the gun. if you're gonna drop £400 on the hobby then a £400 gun on its own won't be nearly as enjoyable as a £150 gun with £250 worth of various accessories, and i say that having made that exact mistake.

for posterity i'd like to point out that whilst i'll use popcorn memes as a tool for communication i generally preferr my snack foods to taste better than their container...... which is why i now have a bag of maltesers sorrynotsorry

at this point should we maybe rename this thread to the grand unified theory of airsoft? i think so far the only topic we haven't taken a tangent into is the #knownfact that tm recoils don't abide by normal physics oh bugger....

thought i had it for a while there, but now i'm definitely lost again.

yep, definately 2 different conversations going on here..... at this point i'm not even sure what the point that's trying to be made is

presumably by being a man of taste and refinement?

you're literally just describing the three variables in the kinetic energy equation wherein Ek=0.5*Mp*Vp^2 but that's far from the only equation at play if you want to know the answer to how much energy a bb with given starting properties (mass, energy and spin) will have at a certain distance, or indeed as most airsofters really care about how much distance can they get the bb to go.

i'm starting to think there are 2 very different conversations going on here........

ahh yes, that does seem to be the case, as i mentioned it doesn't seem the "drag crisis" which could do something like this, applies to airsoft. Internal mechanics are a whole different kettle of fish. there's a lot of work could be done for example in looking at pressure curves for given energies and barrel lengths/diameters to find out if there's an optimum. so say an Xmm barrel with a Ymm wall clearance to the bb has the most stable airflow around the bb at X energy, what wall clearance would be needed to acheive the same stable airflow for a shorter barrel to acheive the same level of stability? where do the limits lie? and that's before even considering the requirements for achieving this, such as for a given volume of cylinder whether it's better to have a full stroke piston that will start compressing with the piston already at a higher velocity, or a short stroked piston that starts at a lower velocity but has a stronger spring to compensate. there's plenty of anecdotal based information, eg folks saying "x-y" is the optimum barrel length, or "use widebores for X application tightbores for Y application" but i've not seen any hardcore nerd-time testing/simulation on the subject. i suspect any benefit within the extremes is probably small enough that getting a system consistent enough to even notice would be it's own challenge. the real answer of course, is whilst it's fun to think in hypotheticals, those who say "screw that, just get closer" do have a valid point

it is technically possible, depending on the difference in energy, and difference in bb weight used. for example (and i haven't checked these numbers) if you were talking a 0.48g fired at 1j compared to a 0.2g fired at 1.3j then the 0.2g would lose energy faster, and at some distance would pass the 0.48g bb and from that point on the heavier bb would have more energy at range. combine that with the fact that as the 0.2g slows it falls further out of the sweet spot for magnus lift and it magnifies it even further. however if we're talking bigger energy difference, say 0.48g at 0.5j compared to 0.2g at 1.5j then it'd be a different story.

when it comes to airsoft projectiles when you do the math on this it ends up pretty linear: for fixed bb weight, more energy at muzzle also means more energy at every point along its flightpath (including extending said flightpath) for fixed energy, more bb mass means the same energy at the mozzle, but higher energy at every point along its flightpath (including extending said flightpath) any combination of both (more energy and more bb weight) increases both. it is also possible for a given range that a heavier bb fired at a lower energy can land with more authority than a lighter bb fired at a higher energy. there was some discussion a while back about the "drag crisis", most notable for its implementation with the dimples on a golf ball, but best i can make out our bb's are too small and travelling too slowly for this criteria to matter. as for when it hits a target, well generally speaking our bb's don't really deform nor do they penetrate their target, so the energy transfer is pretty much whatever energy the bb has at the time.

that laser mount though

i was talking generically, but having started on the kind of site who is the exact kind of place that spawned this thread, ie testing new starts on site .2's and using regulars weight when said regulars would happily chat away about how they were under the "fps limit" when using heavier ammo i do disagree. as a newcomer it very nearly put me off airsoft, going somewhere with admittedly no better chrono practice but a more honest playerbase had me thinking "holy **** this game isn't supposed to leave you with stinging welts every time?" granted that's not joule creep, just very lazy/ignorant chrono practice, but well within the purview of what could be achieved accidentally. the general point is that spicy hardware makes the hobby unappealing, both to new and experienced players. yes if we were to test all guns equally that would indeed be the case. however regardless of which method is chosen, what needs to happen is for marshalls to know which types of guns are susceptible to problems and give those specific players a bit more time and attention. i've lost track of the number of times i've chrono'd on heavier ammo only to get a "that's a bit low" remark, and the only time i've ever seen an hpa regulator locked was the time i locked my own regulator to show the site marshalls that it was a thing you could do. i agree as a practical matter that absolutely eliminating spicy hardware is an impossible task, at least for as long as airsoft is a game played by humans and chronographs only read projectile velocity, but that doesn't mean we should give up on it. yes, however the point i was trying to make was that we can't hope to catch a determined cheater, you know as well as i how easy it would be to bypass any of the methods be it using site ammo, using player weight or hell even a site that issued only its own guns. the point of asking player weight is it'll catch the people who are honest but ignorant, those who own joule creep susceptible guns but don't understand more than "use heavier ammo it goes further". which as has been pointed out is becoming more and more popular especially hpa.

i'm not saying i disagree with such a subjective assessment.......

to answer one of the questions in the ad about the lack of safety- it's done when using a speed trigger which essentially keeps the trigger pulled almost all the way and means the default safety block won't engage. it's possible to modify the safety to account for this, but it's equally easy to just disconnect the airline if you want to safe the gun. it's a tricky one, price wise it's a bit steep for a jack build, and whilst aesthetically it might not be to many folks tastes it probably is pretty damn good for speedsofter shenanigans.

as has already been mentioned, as a mechanism to catch a determined cheater there's holes in pretty much any method you care to name. the best we can hope for is to catch the honest but ignorant cases, the lazy cheaters and follow that up with decent in-game marshalling to weed out those who slip past. i can't say i agree with the whole "being XYZ over doesn't really hurt any more", if that's the case why not raise the limits? why have limits at all? it's all well and good to play the manly man who doesn't feel pain on the internet, but remember this hobby is supposed to be fun, and not everyone thinks pain is fun, and that is not a character flaw. after all, if the energy of a hit doesn't matter why play airsoft instead of paintball?

i mean that's as valid a reason as any in this hobby, carry on

i recall reading a guide that went something along the lines of "if you aren't concerned for the continuation of the next generation you haven't got it far enough up your leg" however i'd simplify that to the correct way to wear a drop leg holster is to have it so far up your leg it's on your shoulder.
