Intro and Flight Footage
5X5 Review Scoring



Avant’s Mostro is no slouch. Built for competition class performance, Avant designed the Mostro to feel at home going head-to-head with the best pro platforms out there but, to our surprise, it can calm down and provide a stable platform for the advancing pilot or the weekend warrior.

With Avant’s Monoblock design and their extremely well-behaved Rigid Core head design, the Mostro e700 is a Ferrari that you can drive cross-country without needing back surgery once you’ve reached your destination. The Rigid Core head smoothes out the typical kinks of DFC design and gives you a silky, smooth feel not typically associated with DFC. Shoot to the stratosphere and try your luck at inverted autos and the Rigid Core head shines once again by keeping that precious inertia in check so you can spot the skids without so much as cracking an egg.

Check out the videos and see what the real deal is with our take on the Mostro. There’s a negative in there, sure, but you weigh out the pros and cons to see if the Mostro e700 is the next bird to grace your hangar!
