one thing i noticed about these springs is its not irregularly pitched...meaning, the coil is the same throughout the length of the spring...is this good or bad?...i've came through systema and guarder springs, even element, and they're all irregularly pitched...

Yep thats right its a variable pitched spring like PDI's. The only advantage i can think of a variable pitched to irregular pitched spring is you can never go wrong when installing it, theres no wrong side, walang baliktad. Sa irregular pitched kasi you need to install the spring in a way that the most inactive coils(side in which dikit-dikit yung coils) are on the spring guide side.

Yes, local company, but we will get from the best manufacturers worldwide. Like spring, USA is one of the most popular player worldwide. Batteries, Japan is the most famous worldwide. So TU batteries, only uses Japan cells. Not Korea, China Class A and China Class c battery cells.

Regular pitch is easier to drive for higher Rof. Fps is the same. A good spring depends on the spring wire material. TU uses only American Made Class A spring wire. Second, the tempering is important. A lot contains 2,500 pcs of springs, then heated and treated together in a computerized oven. The more expensive and hi-tech the oven. The more least discrepancy the tensile strength each spring. each TU AEG spring is plus minus 5 percent of the target tensile strength which is above international standards. The international standard is plus minus 15percent. Which means the plant is big to buy such an oven. Third, the tempering temp in the oven should be computered control. If too hot, the spring would be harder, but would not last long. If temp not sufficient, the spring would be too soft. Ex. just like buying a 130, but output is 120 or sometimes l like a 140/150 which happens to inferior products. Lastly, TU is ZInc Plated to avoid the rusting or deterioration of the item which most competitors do not have.

A local company that first introduces the first American made AEG spring worldwide. Mabuhay! Mabubuhay pagsinuportan ninyo. he, he, he...

Thanks everybody for supporting the TU batteries. At least, now you know your buying japanese battery cells inside a TU lipoly. And also, the tootsie 1450mah 15c, chicklet 1450mah 15c, 1800mah 15c(bar), 1800mah (3way split) and the 2000mah 15c (2 way split) are all using our exclusive customized molds.Sizes are designed for Airsoft guns which TU again is the first. You can not see this sizes in Hong Kong and China. Na frustrate ako na di ko makabit mga battery sa handguard. Kasi dati yun Lipoly natin dito for Helicopter lang.

@anotherME:
noob question po yon....
====================

kuha ko na eto.
the spring itself or the materials came from USA but not the TU brand.
i mean kinuha sa US ang spring then nilagyan ng brand na TU
parang OEM...
medyo confusing lang ako sa poster...

Anyway, I am just interested when i saw the poster in frontpage
But before that, may nabasa ako na a TU 150 resulted only a 450 to 460fps using 300mm inner barrel.
Which is suppose to be yield the same fps using guarder or systema spring.

Please clarify po...
