For all your attempts to debunk of what is accepted by at the very least, the majority of people on this board as the truth, you have not offered one shred of any evidence nor, a reference to what you purport to be so. You argument carries about the same weight in science as creationism. If you read the physics calculator pages, the text describes in mathematical terms how a paintball will generally perform. It is general in that it does not attempt to account for minute things like temperature, seam orientation (or even their presence), nor the fact that paintballs are not perfect spheres. I have personally observed the effects described by the calculator and feel that it is a fairly accurate description of what happens. So now, put your money where your mouth is. In the Upgrades and Customizing section, describe exactly how spin gives a greater force to a paintball. I am not interested in seeing your empirical 'evidence', I want to see the equations that conclusively define this behavior. If you have a BS in physics, this should be something you can accomplish. Oh and by the way, a aircraft and a helicopter create lift the eact same way. Hence the military classifications "Fixed-Wing Aircraft, and Rotary-Wing Aircraft". Still not clear? Then include this in your post as well. As far as how your gun looks, 6/10. It looks like you painted the barrel with a deferent technique and color set than the rest of the gun. The end of the tank being white, looks a little ghetto but, the grip looks pretty good. Now for all you have mentioned about being in the marines, I have not seen anything from you that doesn't sound like a stereotype.

    We are on a Paintball Forum because I wanted to post a picture of my Toy – because we are on a Web site posting pictures of Toys we use simple language so that all can understand - you want me to get a calculator and spend the day proving that the flatline makes the ball hit harder and go farther. Come on man – it does thanks to back spin. What more? Have trouble sleeping?  www.lerc.nasa.gov

 

    The fact that you want to preach to me about Military Classification is funny because you only play, talk and dream about what I do for a living.

    

Fix & Rotary wing produce lift and use it are the same – true. The way they produce lift and the way it affects each – not the same. Thus my point.

    

Still don’t believe that I’m a marine? - Did I steal your girlfriend? – Sound too much like a stereotype?

 

Well the legends are true – and it doesn’t matter if you think I’m a Marine or not – I’ll still fight for your freedom anyway.  

     

       Keep watching CNN reading your cereal box physics and tell me how the fruit loops taste - because thats as close as you will get.

The backspin does not create acceleration... It doesnt not create lift... What it does is cut through the air.

Why do paintballs slow down? Air resistance. How can you reduce this? Backspin. What the spin does is allow the air to flow over the ball rather than nudge into it and slow it down quickly. Throw a ball with no spin into a pool, spin the ball as you throw it. Much less resistance. Same concept as rifling and a bullet except an inverted technique.

Think of a street as resistance. Ghost-ride a bike with a non-spinning back tire and see how far it goes. Then try it with a bike that has a normaly spinning tire. Same concept but on a more extreme scale. Say the non-spinning bike goes 10ft, while the spinning-25ft. At 5ft, will they hit as hard? ofcourse. The spinnng tire bike at 20ft will hit as hard as the non-spinning if it could make it that far.

Out of a normal paintball's range the Flatline will hit harder because normal paint cant make it that far. But within a normal paintball's range its the same, same muzzle velocity; just less resistance.

Ok - lets use some logic here Gents.  - If the flatline shoots Further, then it would mean that somehow the energy behind it increased - right?  If there was an energy increase then that would mean the paintball would hit harder if you were standing within its Max. Effective Range. Yes, it would. One more thing - I have never engaged anyone on a paintball field more than 50 - 60 feet away. So a 20 to 50 foot increase is good news.

well its a good concept with the gunb but as we all know only vm's can rock the front bottle! And btw a paintball fired from a flatline at around 100 fet will leteraly be slow enough to catch. If you shoot a paintball from a normal barrel it will probably make the 100 ft but it will lose alot of height on its way. They both hit woith the same pressure but the flatline just has longer range since it has more backspin.

UV Halo is correct. The backspin on the ball causes a difference in air pressure on different sides of the ball thus generating lift to compensate for height loss due to gravity. Much like that of a fixed or rotary wing as KillerOne put it.

P.s KillerOne dont try to be smart if you have no idea what you are talking about.

why do you continue this arguement?  can you not see the more you argue the more you are cut-down?

Since the flatline can beat standard barrle's range, it is partly true. If the ball from a stadard barrel cant make it to you while the flatline can hit you, which is going to hit harder? But if its within comparable range I dont see it true, although less resistance would mean longer sustained velocity. Interesting.

Oh my good Lord you guys are a bunch of pansies. First off a flatline does shoot harder than a straight barrel even if both guns are set at 300fps. A shot fired from a gun with a straight barrel and velocity set at 300fps will from the second it leaves the barrel begin to lose its velocity. A spin on a paintball put there by the flatline will hold the velocity longer than a ball with no spin. Besides that your gun looks too bulky, maybe a 9oz, 12oz, or even a 16oz, but not the freakin 20.

It is bulky - but I like. I use to have a remote line, but with the tank in the front and fixed to the A-5 I don't have to worry about my line getting wrapped up on anything.

Experiance tells me simple is better - no line, no trouble.

 

^^^can u explain why?

yalls equation for force was wrong...its actually F=ma .....not F=mV

so, F=ma

and there is a difference. velocity is the change in speed and direction

acceleration is the change in velocity. A=V(sub)f - V(sub)i / t

Vf=final velocity Vi=initial velocity

now what i think that everyone is looking for is the ball's final velocity before it hits the ground(out of the flatline...and out of a normal barrel).

so, ok lets make an example.

lets say two men standing next to eachother are 2 meters tall(about 6.4ft) and both have paintball guns one with a flatline and one with an ordinary barrel.

both paintballs are launched at 300fps, both at the exact same height of 2m and both at an exact horizontal line.

an ordinary barrel will launch a paintball, lets say, 175 feet.  the description of the flatline states that the flatline wil shoot %50 further than ordinary barrels. meaning that the
distance,d,=(1/2)(175) + 175

so, if an ordinary barrel launches a paintball 175 feet, then the flatline will launch a ball 262.5 feet(in this example).

now, lets find out how long it takes each paintball to reach the ground. this will tell us which ball maintains its velocity for the longest period of time, or hit harder at any given point.

first of all, all equations in phisycs are done in units of meters. so lets convert all of out feet to meters.

300fps. lets convert this to meters per second. there are 30.48cm in one foot. so,  30.48cm=1ft multiply both sides of the equation by 300 because the velocity is 300 fps and you get 9,144cm=300ft. so now we have our vaule in some form of meters(centimeters) there are 100 centimeters in one meter. so, 9144cm / 100=xvalue of meters. 9,144/100=91.44meters. so 300fps=91.44mps. thats our first conversion.

our last two conversion are 175ft to meters and 262.5ft to meters. 

first, 175ft.  30.48cm=1ft, multiply both sides of the equation by 175 since our vaule is 175ft, and you get 5,334cm=175ft. next, 5,334cm/100=xmeters. 5,344cm/100=53.34m.  175ft=53.34m

following the same steps, 262.5ft comes out to be 80.01m.  262.5ft=80.01m

now, to find the time, t, that it takes for the ball to reach the ground, you must know the equation for time in relation to the x-axis, or horizontal axis.  it is a fairly simple equation. it is displacement, x,=horizontal velocity, V(sub)x times time, t. x=V(sub)x(t). rearrange it and get  t=x/V(sub)x. plug and chug. t=53.34m/91.44m/s. meters cancel out and you get t=.5828. so, when a ball is launched out of the ordinary barrel it will take the ball .5828 seconds to reach the ground.

next for the flatline.  everybody listen, the reson the ball that comes out of a flatline is because the air is lifting the ball, while at the same time gravity is acting upon it, making it stay at a straight path until the spin wears off.  because of the spin there is less air resistance on the ball from a flatline than there is in an ordinary barrel, meaning that the flatline maintains its velocity longer. to prove it lets go to the equation. t=80.01m/91.44m/s. t=.875. in this example the ball shot out of the flatline stayed in the air .2922 seconds longer than the ball coming out of the ordinary barrel.

due to the backspin that the flatline puts on the ball, less air resistance is applied to the ball, allowing it to maintain its velocity for a longer period of time than the ball from an ordinary barrel.  this means that from the exact moment that both of these balls left each barrel the ball from the ordinary barrel was being slowed down at a higher rate than the ball from the flatline barrel. from this we can conclude that at any point on the balls path, if the targets are the same distance away, the flatline will have harder shots than an ordinary barrel due to backspin and air resistance.

there you go people you got it in words and numbers. if theres any problems with my numbers...which i dont think there is, i know the words are facts and proven and you can just read those.

now we can all stop arguing
