VSTank airsoft spring upgrade
Merry Christmas all! I took my brand spankin' new VS Tiger II oout for a spin this unseasonably warm Christmas morn and promptly stripped a nylon gear when a twig got caught in the drive sprocket. No worries though, I replaced the piece with a spare (I am a veteran RC Tanker now you know) and while I was at it thought I had better upgrade the somewhat underwhelming airsoft gun. Thus my post subject. Does anyone have a line on stronger springs and / or good silicon lube for airsoft units? I would like to get this one performing like my VS Tiger I that I bought form TJM a while back. It shoots through several sheets of papaer at 10+ feet whilst the new King Tiger does not. Let me know what you know if you can spare the time.

Hi and Merry Chrismas!
Use only airsoft gun silicone spray lube.
and a spring you may not need one first try putting a little spacer behind the original spring not on the plunger side on the side where the spring hits the casing this will make the stock spring compress more for a little more punch.

RE: VSTank airsoft spring upgrade
here is a spray bottle you realy only need to lube a airsoft gun 1000 shots to 6000 shots though ,,,, i only use a airsoft gun cleaner rod and a paper towel section on the end of it coated with the oil every so often this makes the bb shoot smoother from the barrel but like every 3000 shots i spin up the airsoft gun like half way so the front port is open and i use a long spray tube and stick it right down inside the plunger chamber and give it a fast blast of the spray oil.

RE: VSTank airsoft spring upgrade
Hey Shelonco,
Thanks for the information. I have been toying with the notion of using a stiffer but shorter spring (less preload but greater spring constant).
My thinking is this: (1.) Although longer preloaded springs may produce sufficient force the fact that they tend to twist/bind in the unit may impare thier function.
(2.) A shorter, stiffer spring would still provide the force needed to accelerate the piston forward but would not bind or twist as much.
The force exerted by an (ideal) spring obeys Hooke's law F = kx which basically states that the force exerted by the spring is proportional to the spring constant k and the amount the spring is compressed (or stretched) x. Thereseems like little else can be modified on the VS Tank airsoft units which are generally good out of the box other than spring preload/spring strength and minimising energy sapping friction. I have a VS Tiger I that shoots really hard and a Leopard that is a bit anemic in the shooting department.
What experience have you had modifying your airsodt units? Any other tips?
Thanks for your time, Merry Christmas and a Happy New Year.

RE: VSTank airsoft spring upgrade
Hi if you put a stronger spring don't go to much stronger or it will cause problems.... also when making the spring stronger you should also take a coil or 2 off the little spring on the side of the gun so it pulls the unit back better ( make the sping stronger with less coils) or the BB's won't load some times if left stock.
Also the VS tiger I airsoft unit is a totally different layout than the A6 and abrams type my tiger I type airsoft never failed me once never had a motor go dead like the other units do i think they use a lower gear ratio in the box on the tiger I and it don't strain the motors as much.
If you use a shorter spring you will have to put a nice spacer behind it to take up the space in the unit.... I think the same size spring but a little stronger will be your best bet .... but like i said before i don't think these units can shoot much harder with these mods ... also what i did is used a reamer and went from the back of the chamber and slightly drilled out the rear of the port that the air flows out and made a nice open rounded edge for the air to flow out smoother...don't go to much or you will go through and mess it up... can also use a drill and slightly make the hole in the nipple a little larger but this may not do anything.

These things are so finicky! I stretched the spring on my KV-2 and lubed the piston/plunger and got much better performance but nothing compares the my desert camo Tiger-I when it comes to airsoft power. I think I'll just look for a slightly stiffer spring then and lube it up well. I don't want to ruin it...yet....

RE: VSTank airsoft spring upgrade
yea you never want to stretch a spring as it weakens it.
you should have tried a spacer behind it first because the springs do not compress 100% so a spacer can be put behind the spring for a little more punch.... you will have to try different size spacers and make the gun work out of the tank so you can test easy... because two big of a spacer will cause it to stop and bind because there will not be enough space for the gears to rotate because of a to large of spacer inside .
