SA = Motor On/Off
This switch arms the motor.
SB = Motor speed: High – Mid – Low
This switch selects between 3 different motor speeds.
LS = Variable thermal setting in condition Thermal
Adjustable thermal setting.
SH = Extra thermal setting (not variable) in condition Thermal 2 (non-returning switch) A fixed thermal setting.
SC = Select Condition: Distance <–> Cruise <-> Thermal
Select Flight Condition.
*)
SF = Motor speed: Turbo
(spring-loading returning switch)
Turbo is for max motor speed.
*)
Optional
(I have changed the physical position between SF and SH switches, see last page.)

  • Page 9: Additional Information

    ADDITIONAL INFORMATION Trim T5 as global elevator trim: ( instead): missing on 16SZ, use T3 Trim T2 is used ”as usual” for elevator trim, i.e. it sets elevator trim separate for every flight condition. Trim T5 is used, at the same time, and adjusts the elevator trim for all (wanted) flight conditions. This trim T5 is useful to set the elevator neutral position (when flying) for all flight conditions at the same time.

  • Page 12 How to change switches on Futaba 18sz: https://www.rcgroups.com/forums/showthread.php?2550020-How-to-exchange-switches-on-Futaba-18SZ- %288FG-14FG%29#post33304351 I have changed between SH and SF, ie I want the spring-loaded switch positioned on the left side. Due to the switch PCB:s being designed for upper left or right side, I had to remove the two switches from the PCB, and then re-solder them to the new positions.
