The FQ777 Spider flies well and with it being stored in it's transmitter makes it very handy. I am not so keen on the feel of the transmitter though and once one of the stick tops popped off during a flight (they are only push on tops).
I found that the Jumper T16 supports the FQ777 protocol and I personally prefer to use this transmitter.
I managed to work out the basic (Ail, Ele, Thr, Rud) mappings quite easily (I guessed it was either going to be TAER or AETR) and by trying a number of channels found the Headless Mode channel. I also googled for information on this and I found a number of conflicting articles. Through a bit of testing I have found that the following channel mappings work for me. I give no guarantee that these will also work on any other Spider 126c as it looks like there are a number of different versions out there.
| Channel | Function | Comments |
|---|---|---|
| 1 | Aileron | |
| 2 | Elevator | |
| 3 | Throttle | |
| 4 | Rudder | See note below |
| 5 | Flip | When flip is enabled, Aileron or Elevator input will perform a flip. Channel 5 should be assigned to a momentary switch so that the Spider does not "lock" in flip mode. |
| 6 | Return to Home | |
| 7 | Headless |
Rudder note; I have added a rudder / throttle mix to channel 3 (15 % rudder) as I noticed that the copter would rise or fall when turning.
I have still to find out how to activate the video and camera modes.
