| Direct servo installations are becoming more and more popular,in the days when we had to use unweildy pushrods to cope with bulky servo motors it was the only way,now we have high torque servo motors to suit all applications,running lightweight wires through the airframe is very effective much in the same way as they do it with full sized aircraft with servo tabs.
Also the tiny servos done for lightweight radio installations can be easily buried into parts of the airframe very effectively.
At lot of the older ways were necessary at the time,we need to rethink our control systems to get the very best from what is on the market today.
