Yes, Jabiru use it too. But I'm pretty sure using push-pull cables with no bellcranks would eliminate any differental action of the ailerons. It might be possible to get some of that back by doing something like what Mark Langford did with his ailerons (where the front edge sticks up into the air

I've been thinking about using push-pull cables for the ailerons rather than the conventional arrangement. Seems to me this could do away with the need for bellcranks and the like, but I'm not sure what the downsides might be. I know push pull cables weigh more than standard aileron cable for a g

Just as aside, my Avid Mk4 has push pull control tubes for elevator and ailerons including a complex aileron "mixer" that allows the flaperons to operate as flaps and ailerons at the same time, and to fold the wings back without disconnecting anything. (Although at low speeds the system can delive

Oh, and I forgot push-pull-cables. They can be bad news, and heavy is the least of it. The more curves there in the housings, the more slop you'll have as they take up the space between cable and housing, and the friction is much higher than a pulley system. There's a very good reason why th
