I want to ask if you know how to solve this problem. I want to use this micro switch with a lever to switch the brushless motor, it would work so that when the switch is not on the motor would be off and when the switch is on I could control the speed of the motor by changing the PWM signals. Basically when I would press the button the motor would run at 100%. I have tried having this switch between the DATA cable at the ETC and the servo tester (PWM controllable) so there is a big response. So as soon as I send a 100% signal to the ETC and the switch is off and then I turn it on the motor will start in 2 seconds which is quite long for my case. It needs as little delay as possible preferably zero. So when the switch is turned on the motor will go from 0% to 100% power. Thanks a lot in advance

 

What are the details of the motor and the PWM controller , information is rather scarce??

 

Motor - T-Motor AT 3530 580kv (4255)

ETC - AT 75A 6S https://store.tmotor.com/h5/#/product?id=904
PWM controller (receiver) - https://www.radiolink.com/r9ds

 

What is the start up mode set to?

 

I have used those types of RC units but only in the strict RC mode, never for other purpose.

 

A micro-switch is not likely to handle the current involved.

 

You have not stated what the problem is,
only your idea of how the problem "might be" solved,
but,
You don't know how to implement your proposed solution,
which seems to be,
using a BLDC-Drone-Motor and Controller to
do an unknown job that it was not originally designed for.

What are You trying to accomplish as an end result ?

In one project, we are building a UAV that deploys its wing after takeoff. The aircraft will eject from a tube. Our goal is that once the wing deploys to the position we want it to (this is what the micro switch is for), we then run the motor and propeller at 100% to keep the plane in the air.
As I wrote I tried putting a switch between the DATA pin between the PWM generator i.e. the receiver and the ETC, but in this case there is a response and the motor starts spinning after 2 seconds from pressing the button. Which is quite a long time.
Sample video with different motor, etc and PWM controller.

 

The ESC for the "Airplane-Mode" Motor/Prop should be Hot and operable at all times,
just like the VTOL Motors/Props.

Your problem is a Software-Automation-Problem.

I would venture a guess that the ArduPilot guys have already done this several times over.

I am vaguely aware of a UK Kit-manufacturer that sells several VTOL Kits which
can fly like a Quad and transition to a Plane seamlessly.

Check-out a YouTube-Channel called "Painless360",
look through the previous playlists on this Channel and You will find ~3 or ~4, or maybe more
interviews/demos with the company that produces these Kits.

Thank you, but do you think it is possible to do this with an existing PWM controller (receiver) and using some cheap electronics. I don't know if it would work that I would use an STDT relay and when the relay is off it would send a 0% power signal and when I turn the relay on it would send 100% power. You could also probably use transistors.

 

Almost anything is "possible",
it just depends on how much You want to abuse yourself,
and how much Money and Time You have to spend.
