These characteristics are acceptable in a very small size, because something that weighs a few ounces won't sustain much damage and nobody really expects it to handle wind. It also gives them lots of energy to release in a crash. The combination of self-stabilizing design and lots of weight for their size, makes for slow response, weak movement authority and no ability to handle wind. In a toy or "Hobby Grade" coaxial, neither is of much concern.Īgain, only my opinions, and I could be wrong, so don't go by my words alone.Ĭoax helis have marginal performance at best. Loss of a tail rotor equals loss of craft, and tail rotors kill more people than main rotors. In full-size helis, this increases safety for both operator/passenger, and those on the ground. The concept behind coaxial is elimination of the tail rotor. The Heli-Baby is a great example of how many high-quality parts are required to make a competent coaxial with full "helicopter" mobility. I think, once you say "Large Helicopter with 500g payload", you're going to save money going single-rotor. The bigger the mass, the more robust the components must be, and that equals cost. As size and mass increase, so do the disadvantages in the layout. I know I'll get clobbered by the usual suspects for this post, but I'll try to wing it.Ī coaxial is a design best suited to smaller toys.
