Electronic Cyclic
Electronics can do a lot, but there is quite a big hurdle to overcome in the fact that dynamics of a model and of a full scale model are quite different.
Things that work on a scaled model may be very difficult to achieve, because 'the mix' required to achieve it drastically changes when we go to different scales : length goes linear, volume cubic etc. So finding a control on a larger/full scale model may be quite more difficult.
