I am hoping to present 3 uses of sequencers which are very interesting and not used often. In return, I am looking for information on the steps(not programming it) on how you use it and the setup and switches and what else is needed. In other words, what is the sequence of steps to accomplish it.
Reviewing Spektrum's Draco setup, no problem if you have their setup and radio. I just want to buy the reversing ESC(assume the programming box is needed) and let me see if I can sequence it. Anybody out there explored it doing their own reversing?
What is sequencing?
It is nothing more than putting correct steps that are timed and loop controlled by a switch or servo.
6 years ago, I had a transport and wanted to start the left engine, wait 5 secs, and then start the right engine(to end flight, stop right engine, wait 5 sec and shut off left engine). Programmed it using the sequencer on the DX9.
Second sequencer allows you to:
1) release brake
2) oscillate brake on nose tire so to control speed as you taxi
3)and to takeoff on runway, release brake entirely.
When you land, switch to position 2, taxi, position 1, and brake goes on.
Go to sequencer one and flip the switch, and shut engine down one by one in reverse.
Wowed them at the club field. Brings me back to the days when I taxied(Plane Captain) my plane. Even used prop reversal to back it up and park in spot.
Here is a short video of the action.
I like projects that don't exist. Looking at motor reversing and clamshells for EDF's(really nothing out there, like thrust vectoring) I decided to program a sequencer that would on landing a transport or single EDF, flip a switch that would open 2 clamshells, and have the EDF spin up to the proper speed) to brake, you then flip the switch, engine goes to idle immediately and clamshells retreat. Not possible.
So, can I reverse the EDF motor so it blasts forward to brake in the sequencer?
Concerns:
high rpms, vibrations of blades running in reverse, what kind of reverse thrust?
So, ran test of running 64 EDF in reverse up to 3/4 speed in tube. It works.
So new project for me, need someone who has explored and set up motor reversing other than Spektrum's way.. This concept would be very interesting to play with pusher/puller planes, especially pusher in a dive or steep approach.
