In this letter we construct the kink D1-brane super D-helix solution and itsT-dual the D2-brane supertube using the effective action of non-BPS tachyonicD-branes . In the limit of zero angular momentum, both types of solutionscollapse to zero radius, giving rise respectively to a degenerate stringconfiguration corresponding to a particle travelling with the speed of lightand to a static straight string configuration. These solutions share all theproperties of fundamental strings and do not have the pathological behavior ofother solutions previously found in this context. A short discussion on the``generalized gauge transformations'' suggested by Sen is used to justify thevalidity of our approach.Comment: 10 pages, latex, typos corrected and references adde
