Скачать или смотреть Inline Servo Speed Reducer - Slower Flaps

A fellow member of the RCgroups.com forum (kiwi_craig) clued me in on the existence of these delay circuits that can be plugged in between a servo and the receiver to significantly slow it down for more realistic operation of flaps, retractable landing gear, speed brakes or whatever your imagine may come up with next.


I purchased 4 for $11 shipped. Also available individually for a little over $4 each: https://usa.banggood.com/5-6V-Steel-R...






For my application, I had to cut off the standard size servo plugs so that I could splice on suitable micro plugs. My original Y-splitter cable had a Spektrum-compatible ZH 1.0 3-pin plug on one end to fit the receiver and a pair of GH 1.25 3-pin plugs on the split "Y" end for the flap servos.


To connect proper to the Y-cord, I soldered GH 1.25 sockets to the servo wires. I had to use that slightly larger size instead of the ZH 1.0 plugs because the smaller ZH 1.0 sockets are only available in PC board surface-mount type and are too difficult to solder wires to. The GH 1.25 plug size is standard on Eachine, Volantex and Xk receivers. Spektrum, Eflite, ParkZone and HobbyZone are all ZH 1.0.


The delay unit seems to do the job. Despite the 5v-6v rating it bears everything seems to do just fine with the 3.7 - 4.0 volts that Spektrum micro receivers, both 1S and 2S versions, send to their servo ports.


There is a one-second delay between switch thrown and control surface operation, so that should be kept in mind when planning to raise or lower something. Now, any aircraft pitching-up or down when flaps are deployed should not be so abrupt and easier to compensate for.






Things are starting to loosen up around here, so I hope to get some planes in the air soon. So sick of being cooped up.


Happy flying....if possible! ;-)
