I recently bought a 1/4 scale super cub on floats and have a few questions about setting up a float rudder. I bought the stainless steel kit from hangar 9 and have mounted it to the left float. I'm familiar with pull pull cables on my other plane but would like to use a servo for this one. There is a hatch on the float that was glued shut. The previous pilot flew without a float rudder and glued it shut. I carefully removed the hatch door with an exacto knife with no damage and am left with a servo arm I found in there with a clevis on the end just sitting in the float! I am going to remove the glue he put on the exit hole for the rod and re-install it. Now for the questions I have. What type of servo should I buy to put in there? It should not get wet but would like to have a waterproof one in there just incase some water ever gets in the float. I've heard traxxas makes a water proof one that is interchangle with futaba and have also heard the standard bluebird servo is waterproof. The plane is equipped with the Futaba 7C-2.4 Ghz system. Since I'm still learning I'd also like to ask the opinion of how to wire the servo to act in harmony with my air rudder. Do they sell a Y connector or can I go into another plug in the receiver? The plane is using ailerons, rudder, flaps, throttle and elevator. I'd also like to mount a kill switch too and need some suggestions on the best kill switch to use. I can also post pics if any of this doesn't make sense without seeing it. Thanks for any help!
