Helitronix has been creating innovative solutions to many common requests from model helicopter pilots since 2003. While they have developed many different products over the years, by far their flagship product is their Helitronix Mixer designed to improve the flight characteristics of flybar-less and multi-rotor helicopters. These are truely world class products that solve real flight issues.

We look forward to see more products from Helitronix.

Multi Rotor Models - The Fundamental Challenge

Multi-rotor model helicopters have been around since the very early days of models helicopters and continue to be supported by many manufacturers. The unfortunate part is those same manufacturers do not always prepare new helicopter pilots for the idiosyncracies of flying without a flybar. Sadly, many magestic scale models become expensive static models. What are we really talking about? The flybar adds significant stability to the rotorhead and enables us to fly comfortably in a predictable environment. Flybar-less rotorheads behave very differently in forward flight and exhibits undesired tendancies especially during descent. More specifically, while descending the model tends to roll to the left or right depending on the rotational direction of your head. Add to that a strong pitch up tendancy when in forward flight just makes flying the model much more difficult.

Prior to products like the Helitronix mixer, it was very common to see expert scale modelers use a scale rotor head on the model for static judging, then change to a flybar rotorhead for the flying portion. The way the points system is structured allows a good pilot to score higher with a non-scale head than a poor flight with the scale rotorhead. This just reinforced an unfortunate duality that scale flybar-less rotorheads were difficult to fly. The exact same arguement can be used when comparing learning to fly with a heading hold gyro versus a rate gyro. In both cases, technology has been effectively applied to make our models easier to fly.
