I've been using a version of this from the beginning, but with one exception - Use Teflon tubing and "music wire" because with moderate temperature changes, the plastic push-rods will change length a bit. May not be enough to bother with but I did a lot of RC flying in another like and found my trim changing all over the palce as the day grew hotter or cooler. A good candidate might be a bicycle brake cable - it's the same principle and the inner component is metal. I not only use this method as a position indicator, I also use it as the position feed-back to my flap positon selector circuit/mechanism. With a "balk" at flap zero, I don't have to look out at the wing to be sure of the flap position when executing a go around. I just push the lever to the up stop and know the flaps are going to stop at the "flaps up" stop. Sure takes the load off when at 50 feet, all ready to land and the tower gives you the go-around command!
