2 New Estes Micro EP RTF Helicopters For First Time Pilots

Jan 01, 2012 No Comments by

Estes has been in business for many years producing quality products that work, and at affordable prices. These two new micro helicopters are fully assembled and perfect for first-time pilots!  The SF161™ is the pod and boom version and includes counter-rotating blades for stability, a 3.5-channel infrared radio system and 3.7V LiPo flight battery.  The Cobra version has all of this plus LED searchlights and factory-applied military decals.  Estes joins the world of mini RTF helis with ready-to-fly choppers that are easy to operate, stable and affordable. I think you’ll be impressed, and I look forward to your comments on these two new helicopters.
