Oh, we do that with LEDs and the sequencer already. You can probably find SPM files that I've posted around Radios with it in there. A repeating strobe like on an aircraft.

Thanks. Was just wondering how short a flash I could reliably produce.

Here you go. There are others. Search for me using the word strobe.

Seems like a good opportunity to ask questions and learn something....how would the sequencer do this without any extra hardware? It will give you the ability to automatically control the pulse width of channel but don't you still need a piece of hardware (e.g. an LED controller or a switch) to take that PWM signal and use it to control a strobe?

Yes, you do.

If you were to do that searching on "strobe" you would find I use the E-flite EFLA520 LED controller. It takes the channel position as an on/off command and uses that to control the LEDs.

There is no "no extra hardware" way to accomplish it. You need something to take the 1-2ms pulse and convert it into many ms for the LED to be visible.

Ok, thanks Andy. I followed the search but not far enough!

Yes a simple switch is needed to light the LED. What I meant is that the intelligence to create a single timed, pulsed flash in response to a switch change is provided by the sequencer and not by a hardware strobe or specialized light controller. I want a single short flash and not a repeating strobe (I already do that on my multicopter lights, see my blog for details). My question boiled down to what is the shortest flash I can reliably produce using the sequencer.

There are no specs, tech notes or manuals on that product on the HH web site. Just a picture and a price and a cryptic comment "Product information will be provided as it becomes available"

Greetings,
I purchased a used DX6 SPMR6750, FW 2.01
Thinking it would be a backup to my DX9, however it cannot import the files from the SD card, was I mistaken?

Prep your sd card with SD FORMATTER tool.

Also make sure your DX9 is also on 2.01

In case it's helpful....from post 52805.

Just depends on your requirements.
Something like this might work for what you want albeit with a little more effort than the E-Flite product.

I’m pretty new to Spektrum and I’m having some trouble setting up an electric glider. It’s a DX18 Gen1 and the RX is an AR7350. The configuration is 7 channels, RA, RF, LA, LF, Rud, Elev, Motor. The controls are standard except the flaps/crow is on the left stick and the throttle is on the left slider.

It seems as though whatever function I assign to channel 5 (gear) isn’t fully proportional. Is there a way around this or do I have to buy an 8 or 9 channel RX?

Can you export your model to the SD card and attach the resulting SPM file please?

All channels are fully proportional. I'd like to see how you have your model configured.

Andy
