Flyzone Seawind - Apprentice SAFE Receiver Installation

Hey folks,

The Flyzone Seawind is an amphibious seaplane with wing lights, flaps, and retracts, and it has taken to the Apprentice SAFE receiver rather well. While the ailerons do not need to be reversed, the elevator and rudder control surfaces do require reversing to satisfy AS3X and SAFE requirements. See pics below for details on installation.

The first step is to remove the canopy by removing the three screws at the top-rear of same, and then removing the two sets of seats which are held in place by magnets. The fuselage looks really large at first, but there are a whole lot of wires which must be managed, organized, and pushed to the rear once everything is successfully tested.

Knowing the elevator and rudder both needed to be reversed, I chose to do it mechanically rather than use servo reversers. The two servos sat side by side with each arm extending away from other servo. I switched the positions of the two servos and changed the arms on each by 180 degrees. This required adjusting the pushrods and sleeves somewhat to keep a smooth curve to their paths, and they did actually cross each other without problem. Hot glue was used to hold the pushrod sleeves in place as seen on pic.

The only need for a servo reverser was to combine retracts and flaps on the Aux2 Channel so both can be used in a coordinated fashion. A "Y" servo extension cable was plugged into the Aux2 port. The flaps lead was plugged into one of the "Y" extensions, then a servo reverser was plugged into the other "Y" extension. The retracts lead was then plugged into the servo reverser.

For the DX8 transmitter, all switches are set to INH, then Trainer is set to Aux1, F-Mode is set to Gear, and Flaps is set to Aux2. On the Servo Screen, Aux1 and Aux2 are both set to Reverse. This allows the Bind Button to activate the Panic function and the F-Mode switch to select between Beginner, Intermediate, and Experienced Modes. The flaps switch will put the flaps and retracts down in Position 0, both up in Position 2, and the flaps midway in Position 1.

After a final check to insure everything is working, the SAFE receiver was hot glued in place on the wood platform, and then the great jumble of wires had to be organized, tied together, and worked back into the rear of the compartment. At that point, canopy can be reattached and seats can be replaced in cabin.

Best wishes,
