The Impulse RC Micro Apex takes everything you know and love from the wildly popular full-size Apex, then 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.

Impulse RC Apex 4 Inch Frame

The Micro Apex incorporates all of the unique innovations pioneered by ImpulseRC and now widely imitated. From the compressed-X arm geometry, integrated camera tilt, front box-section, and split main plate design, to our custom shoulder bolts and arm locking key. 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.

You can expect zero arm slop or movement, zero vibration or resonance, and of course that proven Impulse RC durability you can always trust. All backed up with our full crash damage warranty that covers all carbon fiber and metal parts for 1 year from the date of purchase.
