Hi Angus,

Good idea, but how to do it?
I have bought a servo saver, but the height together with a F3102 servo is taller than the canopy. Besides, the travelling distance is only around 12-14 mm. I wonder if other kind mechanism could achieve the same objective.

若這是 TR2012 韓戰之巫婆獎,那當然是將空間塞滿泡菜啦!

Not new idea: Already used by Vladmir in his F3J:

1 tiny pulley at the end of ballast tube;
2 pull pull wire to slide the snug along the ballast tube
3 use special servo to get 180 deg or more, say programmable servo + program software OR those for robot or sailboat winch (rotates over 1.5 to 2 turns) or landing gear retract.
