Review by: Peter Mitchell
I have been waiting on this spring loaded servo helper since I saw it described on Vladimirs website. I used them in my twin boom Plus model, and they have enabled me to add extra torsion return springs to the elevater/rudder which results in a more positive/accurate control surface movement. Very easy to fit, but one pulley needed its outside dia. to be reduced slightly to stop it fouling the inside tail boom which forms the servo mount position.
