The ImpulseRC Micro Apex 4" Frame Kit takes everything you know and love from the widely popular full-sized Apex and shrinks it down (without compromise) to deliver, by far, the biggest little frame on the market.

The meticulous transformation and extreme attention to detail have created a frame that incorporates years of design experience. Equally comfortable as a sub-250g long-range explorer, or a full-blooded freestyle machine capable of handling the harshest environments.

At the center of mass where the arms meet there is a massive 8mm of carbon fiber, taking the stiffness of a micro-frame to a new dimension so you can enjoy unsurpassed flight characteristics at this prop size.

The Micro Apex incorporates all of the unique innovations pioneered by ImpulseRC and are now widely imitated.
