Seeker HS Underbone

SEEKER HS (High Speed) Underbone is specialized miniquad frame for professional FPV racing. Developed by Alpha Squad Multirotor Team Pilots from USA and Indonesia since 2017, the Seeker family was introduced to give competitive options for pilots with one goal in mind ; winning races!

This particular frame is the lightest frame we offer in our line ups. Build it with lightweight parts and it will be a durable sprinter. SEEKER HS underbone does not come with the lifetime warranty Aluminium T6 7075 cages like its brother the Seeker HS but uses the same 3K twill fully chamferred carbon fiber and hardwares. Our end goal with Seeker HS Underbone is to offer a serious and premium FPV miniquad racing frame that is ready to face fierce competition without the pricetag of a premium frame.
