Tail Pushrod Guide view. Notice the adjustability to allow to adapt for either side of servo mounting.
Tail blade grip view. The Mostro uses tail blade grips with counterweights that lower the forces required by the tail servo to change the pitch.
This lower force makes the movements faster and the servo works significantly cooler.

Swiveling Air Diverter Plate.
An Air Diverter Plate directs the airflow from the Naca Air inlets around the ESC an Motor for cooling efficiency and low drag.
The Mostro Monoblock. This is truly a new approach that we are introducing in the market.
In the design of the Mostro we wanted to have all the mechanics connected by rigid elements without flexible elements
being part of the system unless they needed dampening. The result was the design of what we call the Mostro “Monoblock” ( single block).
In the Monoblock design all elements of the system that affects the gyro sensing are mounted in a rigid superstructure.
No part of it rests on the flexible frames unless it needs dampening.

There’s a second one about 6 inches forward for very high boom rigidity.

Recommended Motor and ESC:
From flying prototypes and testing experience we have found the combination of the Kontronik Pyro 750-50 and the 750-56 depending on what head speed you’re looking for and the Kontronik Kosmik Cool 160 or 200 to be the best power combo we have tried on the Mostro for 12 cell configurations. For applications where very high power is needed we have found that the Pyro 800-48 competition is a power monster. Other configurations and brands will also work great but these are the ones we have tons of experience on with fantastic results.
